PolyMC VS multimc-pkgbuild

No, not really. No one was in charge at the beginning. It was a community project with multiple people having the administrative role at the same time. LennyMcLennington was one of the contributers, but not really an important one. But he removed the administrative rights from the actually important people. Devs like flowln and Scrumplex played a much bigger role. Even after half a year being the only developer at the PolyMC-Project Lenny still heasn't caught up with what other conributers had done in a few months before.

Could I suggest trying a different launcher such as PolyMC? You can get this on deck in Linux linkand sign into your microsoft account to access Java. This version also has the benefit of you being able to get modpacks.

It's still open source, the repo hasn't moved. https://github.com/PolyMC/PolyMC/

The issue is: the main developer freaked out, made a post ranting about political bs, kicked everyone from the GitHub project and now it's been 2 months since it hasn't been updated. The developers who used to contribute to "PolyMC" moved from the "PolyMC" project to the "PrismLauncher" one after the drama.

There was no prompting or provocation towards lenny at all. The code of conduct existed for ages before lenny deleted it on oct 17 2022: https://github.com/PolyMC/PolyMC/commits/358f080c76dbdfc65f32e08448a5e38b78d2bab0/CODE_OF_CONDUCT.md

for polymc literally yes git commit (got deleted but title is there)

First, it's gio that handles trash in SteamOS. Second, after digging into PolyMC's code, it also leverages trash. Was added roughly 7 months ago in this commit: https://github.com/PolyMC/PolyMC/commit/02f30de1c11fa53e61c199032a3280afe618e3b2

Are you using arch or a derivative of it? If so, did you install multimc from the AUR? If so, try uninstalling it, and installing from github. In your steam library, the target for multimc should be "/opt/multimc/run.sh" and should start in "/opt/multimc/".

Depends what you want. multimc-bin will be maintained (for now at least) but I'd keep an eye on how this situation develops and you will lose the self update feature if you use that. If the dev decides to push this more the AUR package might be removed for one reason or another but it probably won't. You can also just download the binaries from the site and you can even use the old PKGBUILD from the dev.
