- I can't find the "GNOME Tweaks" app/tool using Ubuntu 20.04 Software app.
- I can't install GNOME Tweaks using terminal
- Any help is greatly appreciated.
Gnome Tweaks is part of the "universe" repository, so you'll want to make sure that's enabled:
sudo add-apt-repository universe
From there, update
sudo apt update
Then you can install Gnome Tweaks:
sudo apt install gnome-tweak-tool
From there, you can find it in your application menu:
Hope this helps.
