Title:
  Sudo owner changed to user #2001 after update

Status in sudo package in Ubuntu:
  New

Bug description:
  This is a configuration bug that affects the hirsute-proposed version
  of sudo. This bug causes sudo when re-configuring, to assign to an
  unused user id that is neither the end user nor root. The result is
  that sudo will refuse to run, returning an error message that is
  displayed below:

  sudo: /usr/bin/sudo must be owned by uid 0 and have the setuid bit set

  The reconfiguration is the last process that occurs in a normal update
  though because sudo will not be usable at this time, the su command
  with root password must be used instead for accessing root privileges.

  If you have already upgraded from hirsute-release to hirsute-proposed
  and you are affected by this bug, please reinstall, and in release do
  sudo passwd root and then configure the password for the root account
  and then once update use su for the time being. Once the bug is fixed
  however please for security reasons delete the root account and use
  sudo for root privelages.
