Ubuntu update backfiring, says it is out of date while it is not

[CMDRSweeper]

My Ubuntu got updated today, with a new kernel appearently, however the problems started with the fact that my "X amount of days / hours since you last updated" stayed at 18 days (Laptop have been powered off for that amount of time.)
So I got a warning triangle up by the clock concerning this update problem as well, with a quick google I found an old thread from 2008 and tried a few of the tricks, reverting between the servers to reload the packages if I am correct, and that fails with the following outputed error:


W: A error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://extras.ubuntu.com maverick Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY DB141E2302FDF932

W: Failed to fetch http://extras.ubuntu.com/ubuntu/dists/maverick/Release

W: Some index files failed to download, they have been ignored, or old ones used instead.

Any idea how to fix this annoyance?

This error has nothing to do with date, it has to do with not having the gpg key for the extras repository. Run the command below to acquire it:

sudo gpg --keyserver hkp://wwwkeys.eu.pgp.net --recv-keys 02FDF932 && gpg --armor --export 02FDF932 | apt-key add -

Did not work appearently :S

cmdrsweeper@sweeperlaplinux:~$ sudo gpg --keyserver hkp://wwwkeys.eu.pgp.net --recv-keys 02FDF932 && gpg --armor --export 02FDF932 | apt-key add -

It did import the key, just couldn't use it due to permission issues. Hmmm!
I always do this as root and have no issues, try without sudo.
I changed my post, it failed to create temp files which I originally was looking for attributes, files that don't exist.
I'm done for now.

The last part of the command should be
sudo apt-key add -

So the command would be

sudo gpg --keyserver hkp://wwwkeys.eu.pgp.net --recv-keys 02FDF932 && gpg --armor --export 02FDF932 | sudo apt-key add -


Good Luck

Ah solved it, what I basically had to do was run the command you initially gave me as root.
By using the "sudo su" command first then removing sudo from your command and I got to do what I wanted to.

Not sure what I did, if I even enabled that repo in Ubuntu, can't tell right now as that machine is tied up. I have three pre-written 'fetch key commands' in notes and just copy and past the appropriate one when needed, same command for all, just change the 8 digit ID to match the key apt says your missing.

Anyway, I'm migrating to Debian Live as I can design my own rather than use a pre-configured live distribution that requires too much persistence space to get it the way you like on a USB key. Plus a live Debian boots as fast as a Ubuntu hard drive install, Ubuntu live USB using the image is nothing short of retarded at bootup. So I have to include the keys to the repositories I plan on adding to the live USB image, the two keys I know I'll need to include are:

dmo-archive-keyring
debian-multimedia-keyring

Both of which can be installed from package manager in a running system. Have a look in your package manager for something like that, in synaptic, use "keyring" in the quick search field.
