Same problem here. Both with my upgraded from Dapper 64-bit desktop and also running the Live Install CD has the same problem.
Frode's suggestion of running from the CL works though. Shadow exists on the Live Install CD though [EMAIL PROTECTED]:~$ ls -l /etc/shadow -rw-r----- 1 root shadow 827 2007-01-07 03:44 /etc/shadow -- User Management Module doesn't load https://launchpad.net/bugs/67013 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
