>From your log: 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
Due to the above issue the service can't restart - and that in turn breaks the upgrade. In a default installation that is linked to the snakeoil key (the default works, but is not safe to be replaced key). root@g:~# ll /etc/dovecot/private/dovecot.key lrwxrwxrwx 1 root root 38 Jan 11 13:51 /etc/dovecot/private/dovecot.key -> /etc/ssl/private/ssl-cert-snakeoil.key The above default is true for Focal (20.04) as well as Groovy (20.10) - so the difference on your system seems to be some manual configuration. Once you fix that up and the service can (re)start the upgrade will be good as well. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1910818 Title: package dovecot-core 1:2.3.11.3+dfsg1-2ubuntu0.1 failed to install/upgrade: installed dovecot-core package post-installation script subprocess returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dovecot/+bug/1910818/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
