Maybe it's related to this problem: KVM + Xenial Server. libvirt-bin won't configure http://askubuntu.com/questions/762924/kvm-xenial-server-libvirt-bin-wont-configure#763935
I had to do something similar to get libvirt-bin started again: $ sudo systemctl stop apparmor.service $ sudo apt-get install --reinstall qemu-kvm libvirt-bin $ sudo systemctl start apparmor.service $ sudo systemctl restart libvirt-bin and then: $ sudo apt-get install --reinstall uvtool uvtool-libvirt Now it all seems to be working again. -- 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
