Title:
  The effects of anacron cannot be disabled

Status in anacron package in Ubuntu:
  Confirmed
Status in anacron source package in Focal:
  Confirmed
Status in anacron source package in Jammy:
  New

Bug description:
  If anacron is installed its effects *cannot* be disabled.

  You can run:
      systemctl disable anacron anacron.timer

  but that will not help. That stops anacron running, but it does *not*
  prevent the run-parts entries in /etc/crontab from running, as they
  only check for the presence of /usr/sbin/anacron, *not* whether
  anacron is actually enabled.

  The test should really be something like:
      systemctl -q is-enabled anacron

  (although that still prints an error message if anacron isn't
  installed - despite the -q. Errors, even intended ones, seem to be
  unavoidable).

  The result is that if you have a desktop system that is permanently
  on, you need to remove anacron - but the next dist-update will put it
  back in place.
