Installation issue

I am guessing there is something obvious I missed.

1. I am on Ubuntu and installed the needed package
2. I installed remotes::install_github("REditorSupport/languageserver" in R

When I ran :LspInstall r_server_language I got this:

    ◍ r_language_server (failed)

Start by reproducing :LspInstall r_server_language on Ubuntu with the reported R version and inspect the getcwd/current working directory errors in the installation output. Trace the installation path involving languageserversetup and REditorSupport/languageserver; done means the command installs the server successfully or the issue documents a confirmed, reproducible fix.
