Problem
When you try to access ubuntu extras you might see following GPG error
W: An 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 16126D3A3E5C1192
W: Failed to fetch http://extras.ubuntu.com/ubuntu/dists/maverick/Release
Solution
Open the terminal and run the following commands
gpg –keyserver keyserver.ubuntu.com –recv 3E5C1192
gpg –export –armor 3E5C1192 | sudo apt-key add -
sudo apt-get update
Incoming search terms:

sudo apt-get update

Could be done this way, too:
sudo apt-key adv –keyserver keyserver.ubuntu.com –recv 3E5C1192 && sudo apt-get update

Thanks xeros, your tip worked
sorry dajomu, xeros worked for me so didn’t get to try yours

@dajomu – This worked for me, thanks!

For some reason this site shows a long dash (-) instead of the two ordinary ones (–) that should be used when typing these commands, so copy and paste does not work. You should check what settings or fonts or something you use here.

@damajou, thanks, your fix worked for me

@dajomu, tried your solution first, sorry, did not work. @xeros, tried your solution as plan B and it worked.
Thanks for the help.

See https://bugs.launchpad.net/ubuntu/+source/ubuntu-extras-keyring/+bug/650525 – the key for the repo seems to have changed to be one other than in the ubuntu-extras-keyring package. Bug report has the latest key in it.
