Thank you for tracking this down. I did make the change in -33.
Yes, I made the change to remove dangling symlinks on uninstall. I
didn't realize this was called on upgrades, so I've moved the logic
inside the "purge" case.
I propose to make the following change to anacron.postrm:
#!/bin/sh
set -e
if [ "$1" = "purge" ]; then
# here for historical reasons
rm -f /var/log/anacron /var/log/anacron.[0-9]*
rm -rf /var/spool/anacron
# Close bug #993348
rm /etc/systemd/system/multi-user.target.wants/anacron.service
rm /etc/systemd/system/timers.target.wants/anacron.timer
fi

Do you agree with this change?
