Hi Sonny, the issue is that after an upgrade services have to be restarted - this fails in your case. The logs that are submitted are not helping to point at any particular issue, but the TL;DR is that the configuration of postgresql has to be fixed so the service can restart.
If you have no custom postgresql-10 config I'd recommend to get back to the default which usually works fine. You can check which are modified with $ sudo dpkg --verify And then restore some as needed by moving them away as a backup followed by $ sudo apt-get -o Dpkg::Options::="--force-confmiss" install --reinstall <package-name> ** Changed in: postgresql-10 (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/1787987 Title: package postgresql-10 10.5-0ubuntu0.18.04 failed to install/upgrade: installed postgresql-10 package post-installation script subprocess returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/postgresql-10/+bug/1787987/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
