Bug#657561: apt-get chokes on bad files, needs manual intervention to fix the situation

[Kjetil Torgrim Homme <kjetilho@ifi.uio.no>]

I'm chiming in, although I observed this on Ubuntu Precise (apt
0.8.16~exp12ubuntu10.21):

        W: GPG error: http://repo.i.bitbit.net precise Release: The
        following signatures were invalid: BADSIG 40976EAF437D05B5
        Ubuntu Archive Automatic Signing Key <ftpmaster@ubuntu.com>

the reason for this was:

        root@backend:/var/lib/apt/lists# ls -l *Release*
        [...]
        -rw-r--r-- 1 root root     0 Jul 20 13:46 repo.i.bitbit.net_ubuntu_dists_precise_Release

IMHO "apt-get update" should delete files it thinks are corrupt and
retry the download before reporting the problem.  alternatively "apt-get
clean" could be more aggressive.
