I logged into the dist-upgrade tester VM for main-all, and tried to install lxc:
Setting up lxc (0.7.5-3ubuntu20) ...
AppArmor parser error for /etc/apparmor.d/usr.bin.lxc-start in /etc/apparmor.d/usr.bin.lxc-start at line 40: Invalid capability syslog.
* Starting Linux Containers
dnsmasq: failed to bind listening socket for fe80::ac5d:58ff:fe84:5af4: Address already in use
* Failed to set up LXC network
invoke-rc.d: initscript lxc, action "start" failed.
dpkg: error processing lxc (--configure):
subprocess installed post-installation script returned error exit status 2
So this is a different failure, and maybe even not in lxc itself. I think this should also be handled more gracefully.
I'm still trying to reproduce the original error, so that I can set -x the init.d script.
