How to update virtualmin - module not shown

Hello,

ich have running:

  • Debian Wheezy
  • Webmin 1.820
  • Virtualmin 4.00.gpl

I do not know how Webmin and Virtualmin were installed since another admin did that. I found webmin_1.630_all.deb with a timestamp from 2013 so I guess that was used to install.
Virtualmin works fine.
Virtualmin is shown in Webmin under “Servers”. I do not have tabs at the top.
Virtualmin does not get updatet as all the other modules.
dpkg -l ‘webmin*’ doesnt show any virtualmin.
“virtualmin” on commandline works.

How do I update virtualmin now?
What information is missing?

Thanks

I simply resolved this by installing virtualmin as deb-Package from webmin.com
http://www.webmin.com/vdownload.html

Then I installed via
dpkg -i webmin-virtual-server_5.04.gpl_all.deb
and it worked
