I've got a problem with apt on my debian box. Since the beginning of July I've been unable to update packages, apparently because some key expired. I've found several websites that tried to help me, but none of the solutions provided worked. Therefore I am asking here.

When I run "apt-get update" I get this error:

# apt-get update
Get:1 ftp://85.17.159.15 etch Release.gpg [1032B]
Get:2 http://security.debian.org etch/updates Release.gpg [835B]

W: You may want to run apt-get update to correct these problems

I tried downloading and installing a new key but it did not solve the problem. Any clues?

  • Could you please post your source.list? Why are you using IP addresses directly?

try this :

gpg --keyserver pgpkeys.mit.edu --recv-key  9AA38DCD55BE302B
gpg -a --export 9AA38DCD55BE302B | sudo apt-key add -

That's a recent Debian system in order to avoid sources corruption

  • +1. You could also use 'apt-key add' to add new keys later.
