Public bug reported: I believe this is the same as bug 1386465, but I'm opening a new one to collect apport info.
I upgraded from 14.04 to 16.04 and can no longer start libvirtd. The output of journalctl -xe shows: Nov 30 19:08:10 kat-Dell-System-XPS-L322X sudo[5547]: PAM unable to dlopen(pam_winbind.so): /lib/security/pam_winbind.so: cannot open shared ob Nov 30 19:08:10 kat-Dell-System-XPS-L322X sudo[5547]: PAM adding faulty module: pam_winbind.so Nov 30 19:08:10 kat-Dell-System-XPS-L322X sudo[5547]: tristan : TTY=pts/18 ; PWD=/home/tristan ; USER=root ; COMMAND=/usr/sbin/service libvirt Nov 30 19:08:10 kat-Dell-System-XPS-L322X sudo[5547]: pam_unix(sudo:session): session opened for user root by (uid=0) Nov 30 19:08:11 kat-Dell-System-XPS-L322X systemd[1]: Starting Virtualization daemon... -- Subject: Unit libvirt-bin.service has begun start-up -- Defined-By: systemd -- Support: http://lists.freedesktop.org/mailman/listinfo/systemd-devel -- -- Unit libvirt-bin.service has begun starting up.
