Unable to install Forge 1.20.1 on Linux via installer - java.io.EOFException

[Nuclear_Man_D]

I solved this already, but basically I was getting java.io.EOFException while installing Forge.

From the (scarce) other forum postings on this, I needed to either clear the temp directory or delete some folder in `.minecraft/libraries`.  The other forum posts were for Windows, so I have no idea what temp folder they mean exactly, I doubt it is `/tmp`.  If someone can clarify where the download cache is for the Forge installer on Linux, that would be really nice.

 

Solution:

In terminal, `cd` to your `.minecraft` folder, likely this command is what you want: `cd ~/.minecraft`.
Run `find -name '*1.20.1*'`, or replace 1.20.1 with the version you're installing.  This shows where the damaged files might be which cause this error.
Very carefully, determine which folders are safe to delete with `rm -rf`.  The commands I ran were:

rm -rf ./versions/1.20.1*
rm -rf ./libraries/de/oceanlabs/mcp/mcp_config/1.20.1*
rm -rf ./libraries/net/minecraftforge/fmlcore/1.20.1-47.3.22
rm -rf ./libraries/net/minecraftforge/forge/1.20.1-47.3.22
rm -rf ./libraries/net/minecraftforge/mclanguage/1.20.1-47.3.22

After this I reran the install and it worked fine.
