Am I the only one where EA App, Epic Games Store and Ubisoft Connect don’t install games properly?
Probably not, but you may have missed the posts where updates to those platforms means that only the Git version of Lutris currently works for Ubisoft, and although the EA App also changed, a working recent WINE version to install it is essential.
If absolutely nothing is installing, then you should post your logs - you’re probably getting permission errors.
