Bug description

I can't install LSP servers from raw.githubusercontent.com (e.g. lsp-java & lsp-metals). I get error:

"LSP :: Server metals install process failed with the following error message: (error Attempt to accept output from process raw.githubusercontent.com locked to thread #<thread 0x9fe8a0>)."

Steps to reproduce

In .emacs: (add-hook 'scala-mode-hook #'lsp)

In Emacs (scala-mode + lsp-metals + lsp installed):

• M-x list-packages
• U
• x

In terminal:

• rm -fr ~/.emacs.d/{.cache/*, auto-save-list/,semanticdb/*}
• emacs test.scala

In Emacs:

• M-x lsp-install-server
• metals

LSP :: Server metals install process failed with the following error message: (error Attempt to accept output from process raw.githubusercontent.com locked to thread #<thread 0x9fe8a0>).

Expected behavior

metals should install flawlessly.

Which Language Server did you use?

lsp-metals / lsp-java

OS

Linux

Sorry tried again multiple times and ended up working...

Seems the only difference this time is that I refused to install the server when automatically asked at opening of the .scala file, then manually asked for the installation using M-x lsp-install-server

Not sure if the problem was on my side, on Emacs side or on GitHub side...

I saw that bug as part of multiple installations, we will have to investigate it. Most likely we will remove threads from the install process.

was running into this in emacs 27.1 / ubuntu 22.04 as well. Running lsp-install multiple times didn't do anything for me, but I quit and re-started emacs and after that i was able to install it successfully. No explanation for why but it did work for me.
