Thanks for filing this bug in Ubuntu. It's not clear why the postfix postinst script failed. I suggest you look in /var/log/mail.log and /var/log/mail.err to see if there is more helpful information there.
Since there is not enough information in this bug report to diagnose the problem, I'll mark it as incomplete. ** Changed in: postfix (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Server, which is subscribed to postfix in Ubuntu. https://bugs.launchpad.net/bugs/1850183 Title: package postfix (not installed) failed to install/upgrade: il sottoprocesso nuovo pacchetto postfix script pre-installation è stato terminato dal segnale (Terminato) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/postfix/+bug/1850183/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
