Comment 3 for bug 572080

I had a look into the log files and it seems several packages failed installing/updating because they tried to create a new user, and the /etc/passwd was locked (by a stale /etc/passwd.lock file, which I had to remove manually.) So the question is, which update left behind a /etc/passwd.lock file blocking the rest of the updates (festival, net-snmp, and more?) ?
