I had to use flatpack to install Bottles, I'm on Porteus because it's the only distrib I found that would fit on a 15 year old 512MB USB stick and then in the RAM directly... Let just say it wasn't a seamless experience but I'm glad I managed to run Cinema4D R20 or MPC Software with Bottles without too many bugs. Anyway Bottles is just fantastic, I tried Wine before but it never worked properly, but having to install a package manager (flatpack) on top of another one (slackpkg) just felt absurd...
What about appimage instead, like Krita? To me it's sounds like the best way to distribute a linux app in 202X...
Managing to make things run on Linux gives a sense of accomplissement, at the same time, I can understand why most people won't move to Linux anytime soon given all the complexity involved... or it's just me and there was an easier way to install flatpack at first place?
