errors instaling virt-manager on 11.10

[Marius Gedminas]

Somehow your replies got quoted alongside my questions, which makes the
reply hard to read.  I've tried to untangle the quoting levels.

Note: I explicitly asked for /etc/passwd* with a * at the end, because I
think useradd uses a lock file named /etc/passwd.lock, and I wanted to
see if it existed.

Ok, so it's not mounted read-only because of errors.  (Didn't think it
was likely, just wanted to be sure.)

Ok, that's the same error:

So, is there a file named /etc/passwd.lock?  If you remove it and try

  sudo dpkg --configure -a

will libvirt-bin be able to add that system user it's trying to add?
