My courier-pop and courier-imap servers won't start. I'm using an old Ubuntu 6.06 box. I did an
apt-get update and
apt-get upgrade 2 days ago, which may have messed things up (there were a few errors). In any case,
/usr/sbin/pop3d no longer exists. This is a file that the courier-pop startup script calls.
I always back-up the machine fully before doing an update and when I extracted the backup to see if I could restore that file from there, the backed-up-copy is present but it has 0 file size and no permissions. I'm stuck. I didn't realize an update / upgrade could corrupt things.
