Thank you for taking the time to report this bug and helping to make Ubuntu better.
It looks like libvirtd was not running at the time of an upgrade, and this caused uvtool-libvirt's postinst to fail. So this is a libvirt bug, not a uvtool bug. Reassigning. We've seen a few cases of libvirtd failing to start. I wonder if this is related? ** Package changed: uvtool (Ubuntu) => libvirt (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1641801 Title: package uvtool-libvirt (not installed) 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/libvirt/+bug/1641801/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
