What is your setup? Because I'm using Fedora and installed Unity because I was curious and deleted it after having problems (I don't remember the error though).

Used it on Ubuntu and Mint, 18 & 19.

Installed via Unity Hub downloaded as an appimage.

Well, I don't think a lot of people is going to dispute that ;]
