WineHQ + GitHub Desktop on Ubuntu?
Solution 1:
As a workaround USE THE PREVIOUS VERSION:
To install the previous version (which works and tested bionic ubuntu 18.04 LTS/19.10 eoan/20.04 focal) remove the version you tried to install then do the below (from terminal):
Updated July 2021 for github desktop 2.6.
sudo wget https://github.com/shiftkey/desktop/releases/download/release-2.6.3-linux1/GitHubDesktop-linux-2.6.3-linux1.deb
