Issues installing Virtualmin

Hi,

I'm trying to install Virtualmin on Debian 8 Jessie. I seem to be receiving a weird error.

I've added to my sources.list: deb http://software.virtualmin.com/gpl/debian/ virtualmin-jessie main deb http://software.virtualmin.com/gpl/debian/ virtualmin-universal main

It attempts to install Usermin and then says Usermin doesn't seem to be installed or it needs to be the Debian version of Usermin. Does anyone have any suggestions what I could look for to fix this issue? Should I maybe try install.sh instead?

sudo apt-get install usermin webmin virtualmin-base
