I am trying to install the viva theme for my Debian install. I am having some issues. I am told to use the gnome tweak tool to select the theme. When I run the gnome tweak tool there is a yellow exclamation mark next to the theme selector portion. Through googling i've been told i'm missing extensions. When I try to add repo's detailed by various sources, then install the extensions mentioned, I am greeted with package not found messages.
This is the theme i'm interested in-
One of the troubles i'm having is alot of the posts I find in google refer to Ubuntu and i'm not quite sure that applies to my ditro. Not sure if that is having an effect or not.
I've tried these solutions,
No dice, package not found and the .deb files don't install, it says there were errors but it doesn't give me anymore information, the .deb files are also for ubuntu it would appear so that can't help.
Any advice and pointers to the right info is greatly appreciated! I am new to tweaking gnome and whatnot so i'm not quite sure what to do, keep running into the same walls.
