Hello, I've tried it today, and found some minor isses:

If glib2 already is installed it will conflict with the ubuntu one, so I've added some lines to remove it.

There is something wrong with the compilation of TEST packages, so I've added the --nocheck flag. I know this is not the right fix, but I'm also not sure about how to fix the packages generation. This is just something to make it work until someone doesn't find the right fix.

I've made the fixes available here:
