root cause found: r-languageserver fail to install bash spawn exit 

Couldn't get past the initial install because I have a `~/.Rprofile` that defines my own repo location. 

Local workaround is to comment out this line in your ~/.Rprofile if you have it:

```
local({
  # options(repos=getOption('repos', 'https://ftp.osuosl.org/pub/cran/'))
})
```
Install doesn't bail out at the start. 

I'll submit a PR for a fix.
