Problemillas con extensión ElixirLS: {‘no such file or directory’, ‘edoc.app’}
Hoy he reinstalado VS code y la extensión ElixirLS, y me saltaba este error:
05:05:15.760 [info] Application elixir_ls_utils exited: :stopped

Se arregló instalando:
sudo dnf install elixir-doc
Parece que en muchas distribuciones de Linux erlang viene muy separado.
Aunque no parece relacionado con este error en concreto, mientras investigaba parece que eran necesarios estos otros:
sudo dnf install erlang-dialyzer sudo dnf install erlang-debugger
Como siempre, podemos ver lo que tenemos instalado y lo que hay disponible:
j sudo dnf list installed "erlang*"
[sudo] password for j:
