[Bug 997282] Re: sudo doesn't uninstall completely

[Jonathan Carter]

Sitting next to Bdale (the package maintainer of sudo/sudo-ldap) here at
Debconf. I showed him the bug and he committed it to
http://git.gag.com/?p=debian/sudo;a=summary in around 2 minutes. :)

It might not make it into Wheezy unless there's another critical bug for
the package, however, I'll test it and upload it to Quantal in the
meantime and then look at backporting it. Assigning the bug to me.

  As stated in the error message adding -f to update-rc.d in /var/lib/dpkg/info/sudo.postrm does fix the problem.
  Here's the diff:

  < 	update-rc.d sudo remove >/dev/null

  > 	update-rc.d -f sudo remove >/dev/null
