I think the problem is a dangling symlink: /etc/systemd/system/nut-client.service -> /lib/systemd/system/nut-monitor.service
You can try this, but it doesn't fix the underlying problem it it just makes it so the package scripts don't fail. I was able to remove nut-client by running this command before removing it: sudo touch /lib/systemd/system/nut-monitor.service -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to nut in Ubuntu. https://bugs.launchpad.net/bugs/1444944 Title: package nut-client 2.7.1-1ubuntu3 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nut/+bug/1444944/+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
