I see apparmor DENIED messages: [132257.005761] audit: type=1400 audit(1501333532.752:74): apparmor="DENIED" operation="create" profile="/usr/sbin/libvirtd" pid=32586 comm="libvirtd" family="netlink" sock_type="raw" protocol=0 requested_mask="create" denied_mask="create"
And errors from libvirt trying to connect which match the refusals from apparmor: Jul 29 09:05:14 hostname libvirtd[32055]: cannot connect to netlink socket with protocol 0: Permission denied I tried reproducing this issue on a fresh xenial VM, but libvirt with apparmor worked just fine. I tried the original version from xenial, and the update. The profile is in enforcing mode, and all I get are STATUS messages in syslog. Have you modified any apparmor file in /etc/apparmor.d by any chance? One last thing to try is to upgrade from trusty to xenial, and then install libvirt-bin. ** Changed in: libvirt (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/1707400 Title: package libvirt-bin 1.3.1-1ubuntu10.11 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/1707400/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
