Ошибка при установке unity через unity hub - ErrorsMaster.ru - большая энциклопедия ошибок и их решений

У меня тоже такое было. Не помню что, но 1 из этих пунктов мне помогло
1. Переустановил Unity Hub
2. Добавил через Locate папку с версией
3. Попробовать открыть в папке версию и возможно она добавится туда.

Вообще, у меня была проблема с Unity Hub и когда часто пытаешься скачивать версии, то потом происходят доп проблемы(перестали версии скачиватся вообще ). Я удалил Unity hub, почистил кеш системы и установил опять

Error messages in the Package Manager window

The Package Manager displays error indicators in the Package Manager window when it encounters problems.

System-wide issues

Network connection issues

Error messages appear in the status bar when the Package Manager has detected an issue that isn’t related to a specific package. For example, if the Package Manager can’t access the package registry server, it displays this message in the status bar:

Network error message
Error refreshing assets (or Error refreshing packages)

If your network can’t reach the package registry server, it’s probably because there is a connection problem with the network. When you or your system administrator diagnose and fix the network error, the status bar clears.

If your network connection is working, but you aren’t signed into your Unity account, the Package Manager doesn’t display any Asset Store packages. When you try to use the My Assets context, the Package Manager displays an error in the status bar:

Logged out of Unity account
Click the Sign in button inside the list view to sign into your Unity account through the Unity Hub.

Package-specific issues

If a specific package has a problem when loading or installing (for example, when determining which package versions to load), the error icon () appears in the package list next to the compromised package (A). To find out what the problem is, open the compromised package’s details view to see the detailed error message (B):

Dependency error message

Package Manager missing or window doesn’t open

The Package Manager window might get moved offscreen or hidden by another window. When this happens, it looks like the Package Manager window failed to open. In this case, you can try to reset the window layout (Window > Layouts > Default) and reopen the Package Manager window again.

If the Package Manager window still doesn’t appear, check your Unity Console windowA Unity Editor window that shows errors, warnings and other messages generated by Unity, or your own scripts. More info
See in Glossary:

Failed to resolve packages: The file [<project-path>/Packages/manifest.json] is not valid JSON:
  Unexpected token '}' at 44:1
  }

This error message indicates that your manifest.json file is malformed. It also tells you the line number where the Package Manager failed to parse the file, so you can fix the JSON. There are a number of online validators that you can use to try to correct the problem. Once you save the corrected file, Unity reloads the Package Manager window.

If you upgraded from an early version of the Unity Editor, there may be other problems with your package manifestEach package has a manifest, which provides information about the package to the Package Manager. The manifest contains information such as the name of the package, its version, a description for users, dependencies on other packages (if any), and other details. More info
See in Glossary file:

As of 2019.3, your manifest.json file should not contain any references to the com.unity.package-manager-ui package. You can either reset your project’s package configuration or remove the following line from the manifest’s dependencies list:
```
    "com.unity.package-manager-ui": "2.1.1",
```
Check to see if your project manifestEach Unity project has a project manifest, which acts as an entry point for the Package Manager. This file must be available in the <project>/Packages directory. The Package Manager uses it to configure many things, including a list of dependencies for that project, as well as any package repository to query for packages. More info
See in Glossary uses “exclude” as a package version. This is an obsolete value for the dependencies property. If you find any lines like these, remove the entire line. Package Manager only installs packages that are explicitly included as a dependency in your project, so once you remove that entry, Package Manager ignores the package and doesn’t install it.

If the Package Manager still fails to load, follow the procedure under Resetting your project’s package configuration.

Problems after upgrading Unity to new version

When you upgrade a project to a newer Unity version, the Package Manager automatically updates incompatible packages to newer compatible versions. However, if your package doesn’t compile, the Package Manager displays error messages in the Console.

To correct these messages, read the error messages and fix any problems you can. For example, a package might be missing a dependency on another package or version. In that case, you can try and install the package yourself.

You can also try the following sequence of solutions until you find something that works:

Back up and then delete the Packages folder under your project.
Back up and then delete the package sources in your project’s Packages folder, leaving only the manifest.json file. Then try to reload the project.
Create a new empty project. If the Package Manager window loads successfully, replace the Library/PackageCache/com.unity.package-manager-ui@<version> folder in the failing project with the same folder from the newly created project.
As a last resort, you can reset your project to the default packageUnity automatically pre-installs a select number of default packages (for example, the Analytics Library, Unity Timeline, etc.) when you create a new project. This differs from a bundled package because you don’t need to install it and it differs from a built-in package because it extends Unity’s features rather than being able to enable or disable them.
See in Glossary configuration and add back packages one at a time until it works.

Resetting your project’s package configuration

If a project has too many package issues, you can reset your project back to the default package configuration for the Editor’s version of Unity. This operation resets all packages in your project. This might not fix the source of the problem, but it can help you figure out what the problem is.

Note: You can’t undo resetting your package configuration, so make sure you back up the manifest.json file first or make sure your project is under source control. You can also take extra precautions by cloning your project and testing out the operation on the clone before proceeding.

To return to the default package configuration, select Reset Packages to defaults from the Help menu.

Help > Reset Packages to defaults

Resetting a clone of your project

You can also test the return to the default packages before you perform the final change:

Clone your project by copy-pasting your project folder and renaming it so that it is easy to find (for example, if your project is called MyProject then you could use something like clone_MyProject).
Load your newly cloned project.
From the Help menu, select Reset Packages to defaults.

Depending on the size of your project, this might take a few minutes.
Check that it successfully reset the packages. If so, you can perform the operation safely on the original project.

Package installation fails

If you are trying to install a new package from the registry and it is not working, it might be due to permission problems.

You must have full permissions on the cache folder:

Windows: C:UsersyournameAppDataLocalUnitycache
macOS: ~/Library/Unity/cache
Linux: ~/.config/unity3d/cache

It might be a problem with the network. Check your firewall and proxy settings.

Sometimes institutional environments, such as schools, government offices, or network-protected workplaces set up proxy servers to control traffic between the network and the Internet, and use their own server certificates which are not recognized by Unity or the Package Manager. Talk to your network administrator.

Unable to add package from Git URL

See Repository not found.

No ‘git’ executable was found

If you try to install a package from a git URL, a message similar to this appears:

Cannot perform upm operation: Unable to add package
[https://github.example.com/myuser/myrepository.git]:
No 'git' executable was found. Please install Git on your system and restart Unity [NotFound]
UnityEditor.EditorApplication:Internal_CallUpdateFunctions()

git-lfs: command not found

If you are trying to download a package that uses Git LFS (Large File Storage), you might see this error message:

Error when executing git command. git-lfs filter-process: command not found.

This indicates that Git LFS is probably not installed on your machine. To make sure, you could test it on the command line:

git lfs --version

If you see something like this, Git LFS is installed:

git-lfs/2.8.0 (GitHub; darwin amd64; go 1.12.7)

Otherwise, you can install it by following the Bitbucket GitHub instructions.

Repository not found

If you specify a location that does not exist, a message similar to this one appears in the Unity Console:

Cannot perform upm operation: Unable to add package [https://mycompany.github.com/gitproject/com.mycompany.mypackage.git]:
  Error when executing git command. fatal: repository 'https://mycompany.github.com/gitproject/com.mycompany.mypackage.git/' not found
 [NotFound]
UnityEditor.EditorApplication:Internal_CallUpdateFunctions() (at /Users/builduser/buildslave/unity/build/Editor/Mono/EditorApplication.cs:310)

Check your spelling. To make sure you are using the correct URL, go to the repository’s page and copy the URL from the Clone button:

Where to copy the URL on GitHub (A) and GitLab (B)

Click the button to the right of the URL on GitHub (A) or GitLab (B) to copy the URL to your clipboard.

If the location of the repository is correct, there may be another problem with the URL:

If you are targeting a specific revision, make sure your revision comes last. For example:
https://github.example.com/myuser/myrepository1.git#revision
If you are targeting a revision and the package is not at the root, make sure the path query parameter precedes the revision anchor. For example:
https://github.example.com/myuser/myrepository.git?path=/example/folder#v1.2.3

Could not read Username: terminal prompts disabled

If you are trying to install a package from a private repository that requires authentication, a message similar to this one appears in the Unity Console:

Cannot perform upm operation: Unable to add package [https://mycompany.github.com/gitproject/com.mycompany.mypackage.git]:
  Error when executing git command. fatal: could not read Username for 'https://mycompany.github.com': terminal prompts disabled
 [NotFound]
UnityEditor.EditorApplication:Internal_CallUpdateFunctions() (at /Users/builduser/buildslave/unity/build/Editor/Mono/EditorApplication.cs:310)

This message is likely due to the fact that Package Manager does not provide an interactive terminal or dialog where you can enter your username and password for HTTP, or your passphrase to unlock your SSH key:

With HTTP(S), every time you log onto BitBucket, GitHub or GitLab you need to enter your username and password in a terminal or a dialog box. However, the Package Manager does not provide an interactive terminal or dialog where you can enter your username and password for HTTP(S).

To bypass this, use one of the workarounds suggested in Solutions for HTTPS.
SSH uses a pair of public and private SSH keys. You can add your public SSH key to Bitbucket, GitHub or GitLab and then access repositories without having to enter a username and password.

However, if you have set up a passphrase to keep your SSH key safe, you still have to enter that passphrase in a terminal or a dialog box in order to authorize your key. In that case, you can use an SSH agent that can unlock your SSH key to authenticate with the Package Manager on your behalf.

Solutions for HTTPS

The Package Manager does not provide an interactive terminal or dialog where you can enter your HTTP(S) username and password. To bypass this, use one of these workarounds:

Use a credential manager (Git Credential Manager for Windows or OSXKeyChain). Credential managers handle sending the password without having to use a terminal or a command prompt.
Use git-credentials from a terminal or command prompt. Then launch the Hub from the same terminal so that Unity has access to the cached or stored credentials.
Use SSH to authenticate instead. If you set up your SSH key without a passphrase, the Package Manager doesn’t have to decrypt it in order to authenticate with the Git server. If you decide to use a passphrase for added security, you can still get around the authentication problem by using the ssh-agent on either macOS or Windows.

Solutions for SSH

If you are using the SSH protocol to install a package by Git URL, you might get an authentication error from Git. This typically happens when you set up a private SSH key on your local machine that is protected by a passphrase.

The solution to this problem is to set up an SSH agent that can unlock your SSH key to authenticate with the Package Manager on your behalf. Follow the instructions in the section that corresponds to your operating system:

Setting up OpenSSH for Windows
Adding SSH keys to your SSH Agent for macOS

Setting up OpenSSH for Windows

The native Windows OpenSSH version of the ssh-agent works better than the version available by default with Git for Windows. This procedure explains how to set up the OpenSSH client and add your key to its ssh-agent. If you are using Git for Windows, you can also prioritize the native Windows OpenSSH over the Git for Windows SSH agent:

Make sure the OpenSSH Client is installed by searching for it in the Windows Settings Optional features window (Start > Settings, then search for “Optional features”). This applies to Windows 10+.
Check your %PATH% environment variable to make sure the native Windows OpenSSH location appears (for example, C:WINDOWSSystem32OpenSSH).

Note: If you are already using Git for Windows, make sure the native Windows OpenSSH location appears before the Git for Windows SSH location in your %PATH% variable. This ensures that Windows uses the native Windows OpenSSH agent over the Git for Windows SSH agent.
In a PowerShell terminal, start the ssh-agent process and make sure it starts automatically:
```
# Set the ssh-agent service to start automatically and manually start it now
Get-Service ssh-agent | Set-Service -StartupType Automatic
# Run the ssh-agent process to start the ssh-agent service
ssh-agent
```
Import your key into the ssh-agent by running ssh-add on the command line and then following the instructions. By default, the agent adds the %USERPROFILE%.sshid_rsa key and prompts you for the password.
```
# Import the key
ssh-add
```
To use a different key, you can specify it as an argument:
```
# Set the ssh-agent service to start automatically and manually start it now
ssh-add <your-secure-ssh-key-name>
```
If you can’t remember the name of your key, you can ask the agent to list them:
```
ssh-add -l
```
If you installed Git for Windows, reset the %GIT-SSH% environment variable to make sure that Git always uses the native Windows OpenSSH version of the ssh-agent:
```
[Environment]::SetEnvironmentVariable("GIT_SSH", "$((Get-Command ssh).Source)", [System.EnvironmentVariableTarget]::User)
```

Adding SSH keys to your SSH Agent for macOS

Use the ssh-add command to add your SSH keys to the ssh-agent running on your macOS system. The command parameter you use depends on your version of macOS:

Prior to macOS 12, use:

ssh-add -K ~/.ssh/<your-secure-ssh-key-name>

Starting with macOS 12, use:

ssh-add --apple-use-keychain ~/.ssh/<your-secure-ssh-key-name>

After you run this command, the terminal asks for the password to unlock your SSH key and then adds it to the macOS keychain. However, once you restart your system, every key stored in the ssh-agent is reset.

To prevent re-entering your password after restarting your system, open the ~/.ssh/config file (or create one if you don’t find it), and add the following:

Host *
    UseKeychain yes
    AddKeysToAgent yes
    IdentityFile ~/.ssh/<your-secure-ssh-key-name>

Restart your machine to apply these changes.

Can’t update Git version

If you are trying to update your Git dependencyThe Package Manager retrieves Git dependencies from a Git repository directly rather than from a package registry. Git dependencies use a Git URL reference instead of a version, and there’s no guarantee about the package quality, stability, validity, or even whether the version stated in its package.json file respects Semantic Versioning rules with regards to officially published releases of this package. More info
See in Glossary to a newer version from the repository, but it’s not working, it’s probably because your Git dependency is locked. If you want to update your Git dependency to a newer version from the repository, use the Add package from git URL button and enter a Git URL. For more information, see Locked Git dependencies.

‘Failed to parse Http response’ in My Assets context

If you see the following message in the Console window when trying to download an Asset Store package, there might be a problem with your Asset Store cache:

[PackageManager] Error Failed to parse response. UnityEditor.AsyncHTTPClient![:D](https://forum.unity.com/styles/default/xenforo/clear.png)one(State, Int32)

To solve this problem, delete all downloaded assets from the Asset Store package directory and then try downloading the assets again.

Warning: If your project contains a lot of asset data, this might take a lot of time and bandwidth to re-download everything.

Missing ‘My Registries’ in the Package Manager window

Not all registry providers are compatible with Unity’s Package Manager. If the package registry server you added does not implement the /-/v1/search or /-/all endpoints, your scoped registry is not compatible with Unity’s Package Manager, and doesn’t appear in the My Registries context in the Package Manager window.

Missing MonoBehaviour errors

While building, if there are a lot of errors about Missing Behavior, the UnityLinker might be mistakenly stripping out a component that it thinks is unreferenced. It often does this because the stripping level is too aggressive. For example, if you have a prefabAn asset type that allows you to store a GameObject complete with components and properties. The prefab acts as a template from which you can create new object instances in the scene. More info
See in Glossary in an AssetBundle that references the SpriteShape component in the 2D SpriteShape package, the object might be missing and might generate compiler warnings.

To fix this, you can either lower the stripping level for the UnityLinker or declare the package’s assemblies inside the link.xml file in order to preserve them from being stripped:

<linker>
    <assembly fullname="Unity.2D.SpriteShape.Runtime" preserve="all"/>
    <assembly fullname="Unity.2D.Common.Runtime" preserve="all"/>
 </linker>

For more information on stripping levels and the UnityLinker, see Managed code stripping.

Loading error for hostfxr.dll on Windows

If the Console reports that the hostfxr.dll library was found, but Unity failed to load it from C:<path_to_app>hostfxr.dll, you can fix this error on Windows 7 or Windows Server 2008 R2 by installing both KB2999226 and KB2533623 patches.

I’m looking into learning to use Unity, so I’ve downloaded the Unity Hub as it seems to be the way Unity is forcing us to download their versions from now on. The problem with this is that, every time I try to download any version of Unity through the Hub, I get a message once the download bar has completed along the lines of:

«Incomplete or corrupt download».

I’ve tried downloading plenty of different official versions, with various plugins, even without any add ons to start with, but I always get the same message.

I contacted Unity support, but they’re insisting that it’s my internet connection and I should download versions from the archives. Surely this can’t be the case, as I can download everything else without any issues.

Has anyone else come across this issue and are there any solutions out there?

So I installed Unity Hub to install unity when I clicked to install Unity after fell minutes it just says «Something Went Wrong» so I tried to install unity separately and after I install it says «installation failed» under the editor, I tried everything reinstalls Unity Hub, reinstall Unity, delete files manually, open as Admins, Go through forums, and even tried to get an older version of Unity Hub. If anyone knows how to solve this please answer this post.

Also here is my latest log:

It might be a problem with the network. Check your firewall and proxy settings.

Packages not recognized

If you see a lot of compilation errors, this might indicate that Unity is not recognizing the packages in your existing project. In this case, you might be missing a .NET component.

For Windows:

Download and install Visual Studio 2017 version 15.9.0 or higher with the .NET Core cross-platform development workload selected under Other Toolsets.
Download and install the .NET SDK v2.2.101 component.

For MacOS:

Download and install the .NET SDK v2.2.101 component.
Install any recommended updates in Visual Studio

Use homebrew to brew and install mono:

brew update
brew install mono # optional
brew upgrade mono

If necessary, delete the Library/obj/temp folder under your project and restart Unity.
If you are still experiencing difficulties, try rebooting your computer as well.

  Error when executing git command. fatal: repository 'https://mycompany.github.com/gitproject/com.mycompany.mypackage.git/' not found
 [NotFound]
UnityEditor.EditorApplication:Internal_CallUpdateFunctions() (at /Users/builduser/buildslave/unity/build/Editor/Mono/EditorApplication.cs:310)

Check your spelling. To make sure you are using the correct URL, go to the repository’s page and copy the URL from the Clone button:

Where to copy the URL on GitHub (A) and GitLab (B)

Click the button to the right of the URL on GitHub (A) or GitLab (B) to copy the URL to your clipboard.

If the location of the repository is correct, there may be another problem with the URL:

If you are targeting a specific revision, make sure your revision comes last. For example:
https://github.example.com/myuser/myrepository1.git#revision
If you are targeting a revision and the package is not at the root, make sure the path query parameter precedes the revision anchor. For example:
https://github.example.com/myuser/myrepository.git?path=/example/folder#v1.2.3

Could not read Username: terminal prompts disabled

If you are trying to install a package from a private repository that requires authentication, a message similar to this one appears in the Unity Console:

Cannot perform upm operation: Unable to add package [https://mycompany.github.com/gitproject/com.mycompany.mypackage.git]:
  Error when executing git command. fatal: could not read Username for 'https://mycompany.github.com': terminal prompts disabled
 [NotFound]

With HTTP(S), every time you log onto BitBucket, GitHub or GitLab you need to enter your username and password in a terminal or a dialog box. However, the Package Manager does not provide an interactive terminal or dialog where you can enter your username and password for HTTP(S).

To bypass this, use one of the workarounds suggested in Solutions for HTTPS.
SSH uses a pair of public and private SSH keys. You can add your public SSH key to Bitbucket, GitHub or GitLab and then access repositories without having to enter a username and password.

However, if you have set up a passphrase to keep your SSH key safe, you still have to enter that passphrase in a terminal or a dialog box in order to authorize your key. In that case, you can use an SSH agent that can unlock your SSH key to authenticate with the Package Manager on your behalf.

Solutions for HTTPS

The Package Manager does not provide an interactive terminal or dialog where you can enter your HTTP(S) username and password. To bypass this, use one of these workarounds:

Use a credential manager (Git Credential Manager for Windows or OSXKeyChain). Credential managers handle sending the password without having to use a terminal or a command prompt.
Use git-credentials from a terminal or command prompt. Then launch the Hub from the same terminal so that Unity has access to the cached or stored credentials.
Use SSH to authenticate instead. If you set up your SSH key without a passphrase, the Package Manager doesn’t have to decrypt it in order to authenticate with the Git server. If you decide to use a passphrase for added security, you can still get around the authentication problem by using the ssh-agent on either macOS or Windows.

Solutions for SSH

Setting up OpenSSH for Windows
Adding SSH keys to your SSH Agent for macOS

Setting up OpenSSH for Windows

Make sure the OpenSSH Client is installed by searching for it in the Windows Settings Optional features window (Start > Settings, then search for “Optional features”). This applies to Windows 10+.
Check your %PATH% environment variable to make sure the native Windows OpenSSH location appears (for example, C:WINDOWSSystem32OpenSSH).

Note: If you are already using Git for Windows, make sure the native Windows OpenSSH location appears before the Git for Windows SSH location in your %PATH% variable. This ensures that Windows uses the native Windows OpenSSH agent over the Git for Windows SSH agent.

In a PowerShell terminal, start the ssh-agent process and make sure it starts automatically:

# Set the ssh-agent service to start automatically and manually start it now
Get-Service ssh-agent | Set-Service -StartupType Automatic
# Run the ssh-agent process to start the ssh-agent service
ssh-agent

Import your key into the ssh-agent by running ssh-add on the command line and then following the instructions. By default, the agent adds the %USERPROFILE%.sshid_rsa key and prompts you for the password.
```
# Import the key
ssh-add
```
To use a different key, you can specify it as an argument:
```
# Set the ssh-agent service to start automatically and manually start it now
ssh-add <your-secure-ssh-key-name>
```
If you can’t remember the name of your key, you can ask the agent to list them:
```
ssh-add -l
```
If you installed Git for Windows, reset the %GIT-SSH% environment variable to make sure that Git always uses the native Windows OpenSSH version of the ssh-agent:
```
[Environment]::SetEnvironmentVariable("GIT_SSH", "$((Get-Command ssh).Source)", [System.EnvironmentVariableTarget]::User)
```

Adding SSH keys to your SSH Agent for macOS

Use the ssh-add command to add your SSH keys to the ssh-agent running on your macOS system. The command parameter you use depends on your version of macOS:

Prior to macOS 12, use:

ssh-add -K ~/.ssh/<your-secure-ssh-key-name>

Starting with macOS 12, use:

ssh-add --apple-use-keychain ~/.ssh/<your-secure-ssh-key-name>

To prevent re-entering your password after restarting your system, open the ~/.ssh/config file (or create one if you don’t find it), and add the following:

Host *
    UseKeychain yes
    AddKeysToAgent yes
    IdentityFile ~/.ssh/<your-secure-ssh-key-name>

Restart your machine to apply these changes.

‘Failed to parse Http response’ in My Assets context

If you see the following message in the Console window when trying to download an Asset Store package, there might be a problem with your Asset Store cache:

[PackageManager] Error Failed to parse response. UnityEditor.AsyncHTTPClient![:D](https://forum.unity.com/styles/default/xenforo/clear.png)one(State, Int32)

To solve this problem, delete all downloaded assets from the Asset Store package directory and then try downloading the assets again.

Warning: If your project contains a lot of asset data, this might take a lot of time and bandwidth to re-download everything.

Missing ‘My Registries’ in the Package Manager window

Missing MonoBehaviour errors

To fix this, you can either lower the stripping level for the UnityLinker or declare the package’s assemblies inside the link.xml file in order to preserve them from being stripped:

<linker>
    <assembly fullname="Unity.2D.SpriteShape.Runtime" preserve="all"/>
    <assembly fullname="Unity.2D.Common.Runtime" preserve="all"/>
 </linker>
