[SOLVED] GPG error

[MJWitter]

I was wondering if anyone can give me a hand:

I have been updating from Intrepid Beta through to Final and all has been smooth sailing, except for the last few days I have been getting the following 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://security.ubuntu.com intrepid-security Release: The following signatures were invalid: BADSIG 40976EAF437D05B5 Ubuntu Archive Automatic Signing Key <ftpmaster@ubuntu.com>

W: Failed to fetch http://security.ubuntu.com/ubuntu/di...curity/Release

W: Some index files failed to download, they have been ignored, or old ones used instead.
W: You may want to run apt-get update to correct these problems

Now running apt-get update is what gives the error, so repeating it doesn't help matters.

Anyone have any ideas? (Sources.list below)

Is this just not a case of moving from beta to final, so they have moved the security file versioning, and you are hunting for the final, failing to get the key, and falling back to beta? My guess would be that the error lies in the authenification zone rather than the sources, as you only have what looks like the new version, but the system is trying to marry it up with the old key and then getting upset.
Just a hunch though.

Daveth,

You are probably correct... would you mind explaining the proper method to delete the old key and get the new one?

Thanks!

Neither worked for me!

But, this did:

ALT + F2

sudo apt-get update -o Acquire::http::No-Cache=true

This also worked for me!
