Somethings wrong with update-manager so i ran apt-get update and it returned this.

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

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

Any ideas?

I found a post where someone suggested this command.
sudo gpg --keyserver hkp://subkeys.pgp.net --recv-key 437D05B5
But that didn't work. It returned this.

gpg: requesting key 437D05B5 from hkp server subkeys.pgp.net
gpg: key 437D05B5: "Ubuntu Archive Automatic Signing Key <ftpmaster@ubuntu.com>" not changed
gpg: Total number processed: 1
gpg: unchanged: 1

I'm sure its a new version of that key i need or something like that. How or where do I download it from?

Have you tried sudo apt-key update ?
