I see you removed dovecot on 24th February again - likely to get rid of those messages.
Maybe you also need to remove "mail-stack-delivery".
Do they still show up?

The logs do not hold a lot on the error itself: https://launchpadlibrarian.net/308890872/DpkgTerminalLog.txt

Maybe checking (or providing here) the output of "systemctl status dovecot.service" might help.
OTOH if you have successfully removed it that should say "service not found".
