Hello Kai, Thank you for taking the time to file a bug report.
While checking the attached logs, I noticed that the dpkg logs contain Mai 31 08:12:31 kai-desktop dovecot[220659]: doveconf: Fatal: Error in configuration file /etc/dovecot/conf.d/10-ssl.conf line 13: ssl_key: Can't open file /etc/dovecot/private/dovecot.key: No such file or directory That file is a symlink to /etc/ssl/private/ssl-cert-snakeoil.key, which is generated by the ssl-cert package Have you modified/removed /etc/ssl/private/ssl-cert-snakeoil.key or the ssl-cert package from your system? Since there is not enough information in your report to begin triage or to differentiate between a local configuration problem and a bug in Ubuntu, I am marking this bug as "Incomplete". We would be grateful if you would: provide a more complete description of the problem, explain why you believe this is a bug in Ubuntu rather than a problem specific to your system, and then change the bug status back to "New". For local configuration issues, you can find assistance here: http://www.ubuntu.com/support/community ** Changed in: dovecot (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1930189 Title: package dovecot-core 1:2.3.11.3+dfsg1-2ubuntu0.1 failed to install/upgrade: »installiertes dovecot-core-Skript des Paketes post- installation«-Unterprozess gab den Fehlerwert 1 zurück To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dovecot/+bug/1930189/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
