Sorry, just noticed I used some old aur package https://aur.archlinux.org/packages/minecraft/

Of course. This is official minecraft launcher for arch linux installed by AUR package: https://aur.archlinux.org/packages/minecraft-launcher. You can see link for AUR package on minecraft.net https://www.minecraft.net/pl-pl/download/alternative/ EDIT: english version https://www.minecraft.net/en-us/download/alternative/

I have just found silly workaround for this problem. I opened local http server and I let it serve the $HOME/.minecraft/libraries/net/minecraftforge/forge/1.14.4-28.0.81/forge-1.14.4-28.0.81.jar file. When it is available over http protocol I edited json like this: { "name": "net.minecraftforge:forge:1.14.4-28.0.81", "downloads": { "artifact": { "path": "net/minecraftforge/forge/1.14.4-28.0.81/forge-1.14.4-28.0.81.jar", "url": "http://127.0.0.1/forge-1.14.4-28.0.81.jar", "sha1": "a6b8a678385678706ad499ef04f5bc1bdbbed9ea", "size": 162736 } } } Forge is working fine now. Looks like windows launcher is looking for local libraries when empty url is given. Linux launcher require correct url path here. Are you able to fix this?

I have below error after installing some new version of forge: [11:14:02 INFO]: Minecraft Launcher 1.6.89-j (through bootstrap 100) started on linux...
