Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

I updated my sources.list with

deb squeeze main
deb-src squeeze main

And called

 gpg --keyserver --recv-keys 1C4CBDCDCD2EFD2A

The Result was, that it seemed to import something, so the key was found on this sever!?

Nevertheless now I get the error:

GPG error: squeeze Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 1C4CBDCDCD2EFD2A

  1. How can I disable/ignore the keychecking in apt in general?

  2. What is the adviced way to fix the problem itself. Is there some way to search the key somewhere elese? How would I do that?

Could someone please DELETE the question? I missed the steps to import the key into apt!!! Please do NOT answer the question... –  manamix Feb 5 '12 at 10:59

Just leave it there, maybe someone else has the same problem and will find their solution here. –  knittl Feb 6 '12 at 8:09

You have to add the key to apt using apt-key:

gpg -a --output /tmp/pub.asc --export 1C4CBDCDCD2EFD2A
sudo apt-key add /tmp/pub.asc && rm /tmp/pub.asc

The key is also directly available from the Percona website. Import it as following:

wget -O - | gpg --import
gpg --armor --export 1C4CBDCDCD2EFD2A | apt-key add -

Edit: Percona is going to change their SSH key before the end of this year. See instructions on their website
