I'd also like to install on Ubuntu 7.0.4. In fact if I can't install on 7.0.4 I won't be using Virtualmin which would be sad.
I understand that the automatic install won't work, but the manual install instructions seem to be missing some steps.
I'd raise this as a support request, but I can't find instructions on how to do that either.
I'm a reasonably experienced Linux admin and perfectly happy using apt-get from the command line or compiling from source if necessary.
Is there any way I can install Virtualmin pro onto Feisty or should I give up now?
