[Hoary] apt-get

[Magnus Therning]

For a while now I've been getting the following warning whenever I do an
'apt-get update':

W: GPG error: http://security.ubuntu.com hoary-security Release: The following signatures were invalid: BADSIG 40976EAF437D05B5 Ubuntu Archive Automatic Signing Key <ftpmaster at ubuntu.com>
W: GPG error: http://archive.ubuntu.com hoary Release: The following signatures were invalid: BADSIG 40976EAF437D05B5 Ubuntu Archive Automatic Signing Key <ftpmaster at ubuntu.com>
W: You may want to run apt-get update to correct these problems

A second 'apt-get update' finishes without the warning.

Why does this happen?
Can I do something to make it go away?
