Permission denied when trying to start custom app

I’m running RHEL8 with OOD 2.0.1 using OHPC 2.1.

I’ve got the xfce desktop up and running with OOD so that’s good.

I’m trying to get RStudio running. I’ve got another cluster with CentOS 7 and OOD 1.6 with RStudio working. I’ve copied the app files from there and made the modifications for the match up to this new cluster.

I’m getting this in the output file:

Setting VNC password...
Starting VNC server...

I’ve checked the permissions on that script.sh file and the foo user owns it. Can anyone help guide me through troubleshooting this?

script.sh is the script you’ve provided in your application. (template/script.sh.erb).

I’d check line 185 of that resulting script as that line seems to be the issue.

So script.sh is actually only 34 lines.

#!/usr/bin/env bash

LOL - sorry, this is much easier than I’m making it.

Set the original file template/script.sh.erb to executable. The file is being copied as is, so if it starts as 644 it’ll be copied as 644. It needs to be 755 (or 750 if you prefer).
