Which means there was an important error message somewhere above this, a
message you did not include in this email.  It may be the same as the
one apt gets when it tries to recover, or it may be different.

Whoa.  What happened there?

  $ ls -l /etc/passwd*
  $ cat /proc/mounts

Of course everyone knows that vim is the best text editor in the world. Anyone
who tells you differently is either wrong, lying, or criminally insane. (Or an
emacs user, in which case they are wrong, lying and criminally insane).
