I just got into this same issue. My system is; NAME="Ubuntu" VERSION="16.04.1 LTS (Xenial Xerus)" So, before i install the libvirt-bin, I remember I just messed up my locale settings. I didn't notice that and then I tried to setup virtualization. But it kept failed and finally fond this bug tread. Even any of the work around didn't solve the issue. So accidentally I checked my locate settings by $ localectl. It was like this. System Locale: TIME=en_US VC Keymap: n/a X11 Layout: us X11 Model: pc105 I then changed it to as below. System Locale: LANG=en_US.UTF-8 VC Keymap: n/a X11 Layout: us X11 Model: pc105 great, problem solved. Hope this may help. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to apparmor in Ubuntu. https://bugs.launchpad.net/bugs/1594902 Title: Failed to upgrade to libvirt-bin 1.3.1-1ubuntu10.1 on Ubuntu 16.04 64-bit Status in apparmor package in Ubuntu: Confirmed Status in libvirt package in Ubuntu: Confirmed Bug description: Output from 'apt-get upgrade': Setting up libvirt-bin (1.3.1-1ubuntu10.1) ... initctl: Unable to connect to Upstart: Failed to connect to socket /com/ubuntu/upstart: Connection refused insserv: warning: script 'screen-cleanup' missing LSB tags and overrides insserv: Default-Start undefined, assuming empty start runlevel(s) for script `screen-cleanup' insserv: Default-Stop undefined, assuming empty stop runlevel(s) for script `screen-cleanup' initctl: Unable to connect to Upstart: Failed to connect to socket /com/ubuntu/upstart: Connection refused insserv: warning: script 'binfmt-support' missing LSB tags and overrides insserv: Default-Start undefined, assuming empty start runlevel(s) for script `binfmt-support' insserv: Default-Stop undefined, assuming empty stop runlevel(s) for script `binfmt-support' initctl: Unable to connect to Upstart: Failed to connect to socket /com/ubuntu/upstart: Connection refused insserv: warning: script 'screen-cleanup' missing LSB tags and overrides insserv: Default-Start undefined, assuming empty start runlevel(s) for script `screen-cleanup' insserv: Default-Stop undefined, assuming empty stop runlevel(s) for script `screen-cleanup' initctl: Unable to connect to Upstart: Failed to connect to socket /com/ubuntu/upstart: Connection refused insserv: warning: script 'binfmt-support' missing LSB tags and overrides insserv: Default-Start undefined, assuming empty start runlevel(s) for script `binfmt-support' insserv: Default-Stop undefined, assuming empty stop runlevel(s) for script `binfmt-support' initctl: Unable to connect to Upstart: Failed to connect to socket /com/ubuntu/upstart: Connection refused insserv: warning: script 'screen-cleanup' missing LSB tags and overrides insserv: Default-Start undefined, assuming empty start runlevel(s) for script `screen-cleanup' insserv: Default-Stop undefined, assuming empty stop runlevel(s) for script `screen-cleanup' initctl: Unable to connect to Upstart: Failed to connect to socket /com/ubuntu/upstart: Connection refused insserv: warning: script 'binfmt-support' missing LSB tags and overrides insserv: Default-Start undefined, assuming empty start runlevel(s) for script `binfmt-support' insserv: Default-Stop undefined, assuming empty stop runlevel(s) for script `binfmt-support' Job for libvirt-bin.service failed because the control process exited with error code.
