PolyMC VS GDLauncher

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

I used to use GDLauncher, but I would not recommend installing a launcher that lets issues like this one go by for almost a year without being fixed: https://github.com/gorilla-devs/GDLauncher/issues/1288

Skip all that manual install crap - https://prismlauncher.org/wiki/ or https://support.curseforge.com/en/support/solutions/articles/9000196904-creating-a-custom-profile or https://github.com/gorilla-devs/GDLauncher/wiki

Another way to make it easy, a bit less easy than the prior but a bit more customization - https://github.com/gorilla-devs/GDLauncher/wiki

The latest GDLauncher beta added an option to allow users to manually download problematic mods. You can get it here (click the Assets dropdown) or wait a few days for it to be released as a stable version.

I would have recommended GDLauncher until this happened to me last week: https://github.com/gorilla-devs/GDLauncher/issues/1288

Maybe give a different launcher a try, I use GDLauncher to run modpacks

maybe you could try GDlauncher it allows you to

Personally i use GdLauncher since it's really simple to use, it also automatically installs open jdk for you, something that basically makes the game run better than normal java, and can still manually download mods that have third-party downloads disabled.

Which other launchers could I use instead? – The shunted devs have established PlaceholderMC as a temporary official replacement. There's also ATLauncher, GDLauncher, and PolyMC itself was a fork of MultiMC.
