Package: dovecot-core Version: 1:2.2.27-3+deb9u2 The unattended upgrades removed my dovecot.conf file. Examining this, I stumbled over this:
stagemail:/etc/dovecot# dpkg -P dovecot-common (Reading database ... 55196 files and directories currently installed.) Purging configuration files for dovecot-common (1:1.2.15-7) ... ucfr: Association belongs to dovecot-core, not dovecot-common ucfr: Aborting dpkg: error processing package dovecot-common (--purge): subprocess installed post-removal script returned error exit status 5 Errors were encountered while processing: dovecot-common Regards Harri
