I get these errors when trying to install any version (this ones for 47.3.33 for instance): 

Processor failed, invalid outputs:
    /home/user/.local/share/FreesmLauncher/instances/1.20.1/minecraft/libraries/net/minecraft/server/1.20.1-20230612.114412/server-1.20.1-20230612.114412-slim.jar
      Expected: 9e06bdd77ca6d95b2cced0bf372245f753eeb16a
      Actual:   f1e5a0cc3c9f7c58f26524a43c5badc06ca0bac4

      Expected: 13522e3278befd103064d91a199451df4cd2633f

I've tried sklauncher and freesm launcher and they throw the same error, tried installing it with the official forge installer too but same error. Also tried different versions of java: 17, 21, 24.
Forge for previous versions install fine, I'm on Linux CachyOS.

1. Did you try to remove your system cache or something?

2. Also check jar hash before installing (if it's ok): 

sha1sum jar_name.jar > jar_name.jar.sha1
sha1sum -c jar_name.jar.sha1

Do this a few times with some interval. This can find out if your hash can be different somehow (garbage files inside). 

Also try using sha224sum / sha256sum / sha384sum / sha512sum / shasum.

And do you have any debug mode during installation?

 

UPDATED: and it can be just fixing by chmod'ing jar file. Check its -lZ

I checked the hash like you said and it came back as OK each time, also may I ask what you mean by debug mode during installation?

There was an error during installation


Also I gave the .jar file full permissions too.

You can also try to unpack your jar. Find .../forge/fml/mc-version.cfg and ../forge/fml/conf/mcp.cfg config files. If they exist then what server_md5 value are there?

If you mean inside the installer.jar those folders and files don't exist. At least I'm not finding them.

      Game crash while loading mods

      By HiImScott · Posted

      I tried updating the mods in my modpack which caused incompatibilities so i have tried to revert them back to their older versions i was using before. In the logs it doesnt show me any clear incompatibilities except for tfmg & entity texture features, but when i try to remove those it still doesn't work. I have tried removing the forge-client.toml file which was a suggestion i found on  a few other posts. This is the log file i get. [inline log removed] Any help would be appreciated. Thanks in advance

      Weird crash logs happening for no reason.

      By Brigtato02 · Posted

      I don't use KubeJS, never even heard of it. But after doing what "Ugdhar" suggested earlier in this post with the "config/Mekanism/generator-storage.toml", I tried going into an individual save's serverconfig folder, and just deleting everything except the parcool folder (I have that mod installed.) Then, a bit of loading and temporary freezing later, seems to have worked. Even when quitting to menu and loading back in, or also when quitting to menu, exiting to desktop, and re-launching MC, choose a save and loading it.

      [Mekanism] Broken tags in Mekanism recipes detected, please check server logs for details. You will be missing some recipes and machines may not accept expected inputs. Do you use KubeJS? It is some kind of bug with it and not fixed A workaround is setting "allowAsyncStreams" to false in the KubeJS common config file https://github.com/KubeJS-Mods/KubeJS/issues/1016   For the rest of your issues, keep deleting these files - now it is the jei-server.toml file If the file is not in config, check the worldsave serverconfig folder These files usually break after updating mods, game crashes or force closing the game
