RStudio user interface not working for R 3.6 using runtime.txt

[aplamada]

Bug description

The project has just a runtime.txt with the content

$ cat runtime.txt 
r-3.6-2022-01-01

How to reproduce

1. Build a container using repo2docker

$ jupyter-repo2docker  --user-name jovyan --user-id 1000 .

2. Try to use the RStudio user interface

Expected behaviour

RStudio should appear.
It works fine with r-4.1, or using conda.

Actual behaviour

I get an error.

Your personal set up

• OS: macOS
• Docker version: 20.10.13, build a224086
• repo2docker version 2022.02.0

I think the problem is independent of OS or Docker version.

@manics hmm, I don't fully remember :| I think maybe #1041 was manifesting in reverse wrt the graphics engine? Closest guess.

[aplamada]

@manics and @yuvipanda Thanks for your input. Regarding the if statement - I found something mentioned on #1099.
I am trying to fix it in #1148.

[yuvipanda]

@ryanlovett do you remember why we split which versions of RStudio are available in different R versions?

Thanks for working on this, @aplamada!

[ryanlovett]

@yuvipanda In the case of #1041, RStudio would still launch. For this issue, it'd be interesting to see the output of the rserver command when run manually.

(perhaps simpervisor's start can be passed params to preserve stdout/stderr)
