Hello,
Gnome Tweak Tool is not working. When I install it via the terminal, it shows up nowhere afterwards. I did find it once in the software centre and installed it from there, but it wouldn’t work. The changes I made on the app wouldn’t apply. The shell extension does not work either. I add it to Chrome but the following message shows up on the website : “Unable to locate GNOME Shell settings or version. Make sure it is installed and running.”. How can I fix the problem? Are there any alternatives to change the desktop theme? (Had the same problem with Unity Tweak Tool btw)
