При обновлении Ubuntu выскочила ошибка:
W: GPG error: http://ppa.launchpad.net lucid Release
Данная ошибка возникает при отсутствии GPG ключа, полный вывод ошибки выглядит примерно так:
W: GPG error: http://ppa.launchpad.net lucid Release: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY wsqwer42f43rd
W: GPG error: http://ppa.launchpad.net lucid Release: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY wsqwer42f43rd
W: You may want to run apt-get update to correct these problems
Для автоматического поиска и импорта ключей можно использовать launchpad-getkeys из WebUpd8 PPA:
sudo add-apt-repository ppa:nilarimogard/webupd8 sudo apt-get update sudo apt-get install launchpad-getkeys
чтобы импортировать отсутствующие ключи GPG для PPA, выполните команду:
sudo launchpad-getkeys
When I run the sudo apt-get update, it results in the following
Reading package lists... Done
W: GPG error: http://ppa.launchpad.net lucid Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY A1715D88E1DF1F24
W: GPG error: http://ppa.launchpad.net lucid Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 551CE2FB4CBEDD5A
W: GPG error: http://ppa.launchpad.net lucid Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 1E9377A2BA9EF27F
By googling I came to know the key is missing, and it can be obtained by running the following command with the corresponding hexadecimal numbers
saikirangvr@ubuntu:~$ sudo gpg --keyserver subkeys.pgp.net --recv 551CE2FB4CBEDD5A
But I was not able to fix this as this gave me the error
gpg: WARNING: unsafe ownership on configuration file `/home/saikirangvr/.gnupg/gpg.conf'
gpg: external program calls are disabled due to unsafe options file permissions
gpg: keyserver communications error: general error
gpg: keyserver receive failed: general error
I tried many times but I was unable to fix. I was behind a proxy server in my college and I have configured the Ubuntu well to use behind the proxy.
After using
sudo chown -R saikirangvr:saikirangvr /home/saikirangvr/.gnupg
the problem of unsafe ownership was gone, and it gave the following….
sai@ubuntu:~/gpgpu-sim/ispass2009-benchmarks$ gpg --keyserver keyserver.ubuntu.com --recv 1E9377A2BA9EF27F

sai@ubuntu:~$ sudo launchpad-getkeys
Please wait... launchpad-getkeys is running an update so
it can detect the missing GPG keys
Trying to import all the missing keys

launchpad-getkeys has finished importing all missing GPG keys.
Try running sudo apt-get update - you shouldn't see any key
errors anymore
What is the problem. *Is there any other method to solve this like through GUI *…….
When i run sudo apt-get update, i get the following error
W: GPG error:.
http://ppa.launchpad.net lucid
Release: The following signatures
couldn't be verified because the
public key is not available: NO_PUBKEY
9BDB3D89CE49EC21
I tried searching for it, but wasn’t able to find anything helpful. What is the reason for this, and how can i fix this?
Edit1: I am using Linux mint 9.
Edit2: On sudo add-apt-repository ppa:mozillateam/firefox-stable/ubuntu, I was getting gpgkeys: HTTP fetch error 7: couldn't connect to host, so i did according to this post. When I run sudo apt-get update, it gives no errors. But, firefox 5 is still not installed. In my update manager when I try to install, it says «Fix broken packages first». In Synaptic manager there is an option of «Fix broken Packages», but it does nothing. What is going wrong here?
Edit3: Update is used to resynchronize the package index files from their sources, and Upgrade is used to install latest versions. So, I was forgetting about upgrade!
Thanks!

Edit your /etc/apt/sources.list, and comment out the offending line (add «#» at the beginning of the line). The line you are looking for should have «ppa» in it. Save the file. Pls — note which ppa was mentioned there.
If in sources.list there is no ppa mentioned, check the files in /etc/apt/sources.list.d/ for a file which has «ppa» mentioned in there». Move this file to somewhere (so you have backup).
Then do:
sudo add-apt-repository ppa:any-ppa-that-I-need
This will add the ppa back to sources, but will fetch and install the pgp key as well.

The most direct method is to use apt itself:
$ apt-key update
The Ubuntu Forums have a couple things to say about this using more roundabout methods, if apt doesn’t do it properly.
ok. I figured it out.
do this:
wget
http://packages.freecontrib.org/ubuntu/plf/12B83718.gpgand then open up synaptic and go to
settings>repos>authentication and
«import file key» browse the key and
click ok.and then sudo aptitude update
And this:
sudo wget http://ftp-master.debian.org/ziyi_key_2006.asc -O — | sudo apt-key add —
This is the link to my Google search — there’s quite a bit much there to put in a single response.

Thanks to ChrisJean.com I fixed this entirely in about 10 minutes.
First, collect a list of the GPG errors, by
cd /etc/apt/sources/list/d
sudo apt-get update > listoferrors
Do sudo nano listoferrors and strip out everything but the 16 character hexadecimal strings, and a space between each, then add at the beginning
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys
so the hex strings, with a space between each, follow that apt-key command.
Copy the entire string and paste it into a terminal window with Ctrl-Shift-V. You end up with something like
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 0123456789ABCDEF FEDCBA9876543210 11A11B11C11D11E1
Run it. It goes out, retrieves the correct keys, and puts them in place.
Then, another sudo apt-get update runs without flaw.
Close and delete the listoferrors file.

When you get GPG errors when running apt-get update on your Ubuntu machine, you have to import the the appropriate keys.
W: GPG error: http://ppa.launchpad.net lucid Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 4DEF31B9A9E345C0
W: GPG error: http://ppa.launchpad.net lucid Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 0F678A01569113AE
W: GPG error: http://ppa.launchpad.net lucid Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 7889D725DA6DEEAA
W: GPG error: http://ppa.launchpad.net lucid Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 8CA7A6E8E4FA953A
Just run the following command :
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys KEYID
where KEYID is number shown in error message which is bold & underlined
& you can do the same for every missing key.
