After Upgrading to Fedora 32 on multiple machines, ElixirLS won't start

[hamptokr]

Environment

• Elixir & Erlang versions (elixir --version): Elixir 1.9.2 (compiled with Erlang/OTP 22)
• Operating system: Fedora 32
• Editor or IDE name (e.g. Emacs/VSCode): VSCode
• LSP Client name: ElixirLS: Elixir support and debugger
  • If using VSCode, are you using "ElixirLS: Elixir support and debugger"?

Troubleshooting

• Restart your editor (which will restart ElixirLS) sometimes fixes issues
• Stop your editor, remove the entire .elixir_ls directory, then restart your editor
  • NOTE: This will cause you to have to re-run the dialyzer build for your project

The .elixir_ls directory never gets created, I assume because the ElixirLS application never starts.

Logs

Creating a new project with mix new empty has the same issue.

How did you install elixir and erlang? This looks like errors that people have seen with a partial installation of erlang.

[hamptokr]

On Fedora 31 I used sudo dnf install elixir. The problem arose when I upgraded to Fedora 32. I tried re-installing but same issue. I am able to run phoenix apps and other elixir based tools just fine, but ElixirLS just crashes.

[hamptokr]

The following packages get installed with that command

erlang-mnesia-22.3.2-1.fc32.x86_64
erlang-runtime_tools-22.3.2-1.fc32.x86_64
erlang-parsetools-22.3.2-1.fc32.x86_64
erlang-asn1-22.3.2-1.fc32.x86_64
erlang-public_key-22.3.2-1.fc32.x86_64
erlang-inets-22.3.2-1.fc32.x86_64
erlang-ssl-22.3.2-1.fc32.x86_64
erlang-tools-22.3.2-1.fc32.x86_64
erlang-sasl-22.3.2-1.fc32.x86_64
elixir-1.9.2-2.fc32.x86_64

[axelson]

Are there any other erlang packages available?

[axelson]

Especially any that mention dialyzer.

[hamptokr]

I have the dialyzer package installed as well:
Package erlang-dialyzer-22.3.2-1.fc32.x86_64 is already installed.

[hamptokr]

Uninstalling the fedora packaged elixir and using kiex to install elixir 1.10.3, fixed the issue. Not sure if we want to leave this issue open? It did not work with elixir 1.9.2 on fedora 32.

[chapmanjacobd]

If you do sudo dnf install erlang then it will add all the packages that ElixirLS needs

Added a troubleshooting note to the README. Thanks for the report!
