Module virtualmin not valid

Hello

Using a B grade OS like openSUSE I have to perform a manual and boring installation :stuck_out_tongue:

After a succesfull installation of webmin I tried to install the module virtualmin using the module setting in webmin

I got this response:

Downloading http://software.virtualmin.com/gpl/universal (253 bytes) …
Downloading http://software.virtualmin.com/gpl/universal/ …
… download complete.
Failed to install module from http://software.virtualmin.com/gpl/universal : Not a valid module file : tar: This does not look like a tar archive tar: Skipping to next header tar: Exiting with failure status due to previous errors

Any hint?
