This is why I'm suggesting Pre-Depends: sudo for libvirt-bin. I
think that libvirt-bin.postinst is being run before the newly
created user has been added to the sudo group.

Note that though I marked this high priority, it has been pointed
out to me that tasksel is deemed somewhat obsolete so perhaps the
prio should be lowered.
