Hi, the logs don't indicate a lot, I can only see that it failed to restart service libvirtd. In general if a service fails to start as-is due to any bug/configuration change then an upgrade will fail as it has to restart the service.
The block of virsh/virt-manager just seem like libvirtd being down, witch matches your fail to restart it. You'd have to check a few thing on your installation independent to the upgrade to ensure it is running fine which usually is then unblocking the upgrade. 1. does a "systemctl restart libvirtd" work (repetively) 2. if it does get more data on why 2a. what does "journalctl -xef" while doing so report 2b. consider enabling libvirtd debugging [1] and check the log 3. try to config your system so that libvirt restarts reliably 4. then re-kick the update of the package [1]: https://libvirt.org/logging.html -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1776087 Title: package libvirt-daemon-system 4.0.0-1ubuntu8.1 failed to install/upgrade: installed libvirt-daemon-system package post- installation script subprocess returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1776087/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
