I'm using unity on Ubuntu 20.04.1 LTS and got the same warning

I'm also trying to install the Unity Tweak Tool (NOT Gnome Tweaks) for the purpose of enabling proper workspaces, and I too also get the same error.

It would appear not long ago, the Unity Tweak Tool DID work in 20.04, at least back in May 2020 anyway: https://www.youtube.com/watch?v=UoPvVf1d5PQ

Ummmm.... If this is the wrong package then shouldn't there be a simple check when the app fires? Sorry I haven't taken the time to Google how to accomplish this in python but it's a doable task.
