How to update virtualmin gpl?

I used yum update and it listed webmin, but not virtualmin. What do I need to do? Webmin is updated correctly.

Do you have correct configuration for the repositories? (There is also a yum repository, which I don’t think includes Virtualmin-related packages.)

I have virtualmin.repo in /etc/yum.repos.d/ if that’s what you mean

[root@server yum.repos.d]# yum list updates
Loading "fastestmirror" plugin
Loading mirror speeds from cached hostfile

Or since I have installed webmin first, do I need to download the latest module again? Can I just overwrite that using the "Add" screen?

So, you don’t need to do anything but a yum update. If you don’t see a new Virtualmin version, that’s because you already have the latest (3.66). It’s definitely in the virtualmin-universal repo.

Note that if you’re trying to get it by name, the Virtualmin module is named “wbm-virtual-server”, not “virtualmin”. But a simple “yum update” would find all of the available updates to installed packages. If you didn’t install Virtualmin via an RPM, though, yum would obviously not know you have Virtualmin installed and wouldn’t offer to update it.
