I updated some of my servers to version 5.03 last night.
While most of the updates work perfectly right away, I had some problems during upgrading to this version. - 2 servers didn't (re)start Apache after the update (Debian Wheezy & an Ubuntu 14.04) - One of the servers didn't finish the update. (Debian Squeeze, I know I have to update it soon)
Of course, problem 1 was simple to repair. I could start Apache2 without problems.
I restarted server 3 (the one that didn't finish) after 8 hours of waiting. After using "dpkg --configure -a", I got the following:
Setting up webmin-virtual-server (5.03.gpl) ...
virtual-server/postinstall.pl failed : virtual-server::module_install failed : useradmin::lock_user_files failed : Failed to lock file <tt>/etc/passwd</tt> after 5 minutes. Last error was : at web-lib-funcs.pl line 1427.
Now, I can't access the controlpanel. When I access the server on port 1000, the page keeps on loading and I don't get any response. In the processlist I see an process '/usr/share/webmin/authentic-theme/index.cgi' running on 100% on a core.
I tried changing the theme by editing the config file (/etc/webmin/config) but it didn't solve the problem: also that page keeps loading.
I can't find any errors in /var/log/syslog etc., and I can't find other logs that need to be checked.
What can I do? Thank you in advance for your responses!
