Error installing forge-1.16.1-32.0.7


Recommended Posts



used Minecraft 1.16.1 and forge-1.16.1-32.0.7-installer.jar on Ubuntu 20.04.

Tried different openjdk versions from 8-14, none worked.

Minecraft was running once, stopped via console, this was a fresh install.


My install command : java -jar forge-1.16.1-32.0.7-installer.jar --installServer


the part where it fails : 


 Data  io/netty/internal/
  Processor failed, invalid outputs:
      Expected: 6cbe49c4d26497791d1d511c2d3b7d1fa46fa2e9
      Actual:   3f1b64c684df16a25e6c44079b06ac12131db572

EDIT: Still fails with forge-1.16.1-32.0.14-installer

I think its because a file/ directory is missing. The file "META-INF"  is in the forge installation file but on the installation  program, all files appears except "META-INF" . (On forge 1.15.2 it appears juste above "Data io/netty/internal"). I don't know if its important but my forge 1.16.1 installation doesn't work, even with the update 32.0.15.

(Sorry if my english sucks i'm french )

Forge for 1.16.1 is in BETA. This means crashes and bugs are expected to occur while the Forge dev team is still fixing what got broken during the update.

While 1.16.1 is now in active development and support, it will be a few days/weeks until a stable/recommended release for Forge 1.16.x.

If you are wanting to test and find bugs, by all means please do so and report them to the issues tracker. But, if you're just wanting to play modded 1.16, please wait until Forge is out of beta once again, and until a recommended Forge version is released.

Ok. But it happend also to other people in forge 1.15.2 so its not only in my forge. Ill have to wait till other people will reply. But thx anyway.

I was having the same problem. Continuously crashing on start, I just switched forge version from LATEST to 1.15.2 and that solves the problem because it loads that specific version which doesn't have the bug.

The latest build (32.0.19) should have the fixes that you guys need.

If you have any more issues, let us know.

Yup, I just redeployed the container (running minecraft on  Docker) and changed the version back to LATEST, it pulled version forge-1.16.1-32.0.19.jar and that fixed the problem right up.


Thanks a lot Curle!

    • Came here for the same reason. But for me it's the client. After following your instructions with the jar, I ended up with the following error.
