Package: dovecot-core Version: 1:2.3.4.1-5+deb10u6 Debian 10.10 Dovecot fails to start if cloud packages are removed. The service has "After=local-fs.target network-online.target". Probably the network-online.target is gone, the service started too early, before ip addresses are assigned.
Errors: dovecot[320]: Error: bind(n.n.n.n, 993) failed: Cannot assign requested address dovecot[320]: Error: service(imap-login): listen(n.n.n.n, 993) failed: Cannot assign requested address dovecot[320]: Error: bind(n:n:n:n:n:n:n:n, 993) failed: Cannot assign requested address dovecot[320]: Error: service(imap-login): listen(n:n:n:n:n:n:n:n, 993) failed: Cannot assign requested address dovecot[320]: Fatal: Failed to start listeners dovecot.service is defined here: /etc/systemd/system/multi-user.target.wants/dovecot.service Below [unit]: After=local-fs.target network-online.target This can be fixed by using: After=local-fs.target network.target Or by appending " network.target": After=local-fs.target network-online.target network.target This may work with or without cloud (not tested with cloud). It fixes the problem when cloud functions have been removed. Activate change: systemctl daemon-reload
