missing PUBKEY error

[jimwhitend]

I added and removed some third party software sources and now Update Manager return this error below. What to do? Thanks.

Run the following command, replacing the <key> with the last 8 alphanumeric characters in the error message:

gpg --keyserver keyserver.ubuntu.com --recv-keys <key> && gpg --export --armor <key> | sudo apt-key add -

In your messages, since the keys are the same, you can run this:

gpg --keyserver keyserver.ubuntu.com --recv-keys 437D05B5  && gpg --export --armor 437D05B5 | sudo apt-key add -

Please mark the thread solved via the Thread Tools link near the upper right of the original post when you no longer need assistance.

open a terminal and type:

sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 437D05B5
sudo apt-get update

I've got network problems that I don't have a clue how to solve. The above commands yield this:
jim@jim-ubuntu:~$ gpg --keyserver keyserver.ubuntu.com --recv-keys 437D05B5 && gpg --export --armor 437D05B5 | sudo apt-key add -
gpg: requesting key 437D05B5 from hkp server keyserver.ubuntu.com
gpg: keyserver timed out
gpg: keyserver receive failed: keyserver error
jim@jim-ubuntu:~$ sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 437D05B5

Can you point me to a method to troubleshoot, or a forum that might be helpful? Thanks.

jimwhitend,

I tried importing the key but it appears the server isn't working. I was able to successfully import it via this one, although it took about a minute to complete.

gpg --keyserver subkeys.pgp.net --recv-keys 437D05B5

ok, so i've had this problem once before on my netbook, and i was able to fix it using the info on this forum. Now i've installed the same distribution (easy peasy 1.5) on a VM on my desktop, so i can try out some major changes before i commit, and I
m running across the same issues, but this time I've hit all wall, these are some of the errors I get:

on

$ sudo aptitude update

everythings normal until:

Hit http://us.archive.ubuntu.com jaunty Release
Err http://us.archive.ubuntu.com jaunty Release

and at the end

W: A error occurred during the signature verification. The repository is not updated and the previous index files will be used.GPG error: http://us.archive.ubuntu.com jaunty Release: The following signatures were invalid: BADSIG 40976EAF437D05B5 Ubuntu Archive Automatic Signing Key <ftpmaster@ubuntu.com>



and when i run some of the commands given in in this thread, i get weird things

$ sudo apt-key adv --recv-keys --keyserver subkeys.pgp.net 437D05B5

beloved88,

I just tried adding the key with the command from post 3. It took about a minute but it was imported successfully.

Try opening synaptic and go to Settings, Repositories, Authentication tab. If you have a 437D0... key delete it and run the command again.

[beloved88]

ok, it doesn't work, and I got mad and closed the terminal before posting the results, but it was the same. Did I mention this was a VM clone of my netbook on my desktop? Could i copy the repositories list and keys from my netbook to the VM?
