Any Solutions to making Automathemely work? (I'd like to be able to keep it and using it.)

Start by reproducing the failed Automathemely removal on the reported Linux Mint and Cinnamon versions, using the dpkg and sudo output in the issue as the symptoms to investigate. Trace the package's removal behavior and verify that uninstalling it completes without the reported sudo, crontab, systemd, or dpkg errors.
