Troubleshoot RStudio Server Installation - verify-installation incorrectly reports server is running

I've installed RStudio Server for Ubuntu 20.04, rstudio-server-1.4.1106-amd64.deb; however, it isn't working correctly and I am not getting any useful errors to troubleshoot my issue. I have configured my rserver.conf as follows

# /etc/rstudio/rserver.conf
rsession-which-r=/usr/local/bin/R-devel/bin/R  # I want to use a devel version that I've install here

I've verified that it's listening on the correct port using netstat -natp. When I stop the server and try verify-installation, I get a message that it's still running:

jwokaty@supermicro:~$ sudo rstudio-server stop
jwokaty@supermicro:~$ sudo rstudio-server status

I've also set up logging, but I don't seem to be getting any error messages.

# /etc/rstudio/logging.conf



I get a timeout when I attempt to visit my server on the given port. I would appreciation suggestions to troubleshoot my issue.

Howdy!! And welcome to RStudio Community @jwokaty !

Unfortunately, this is due to an intermittent bug we have where the rserver process does not clean itself up properly. The way to fix it is to look for running rserver processes:

ps -ef | grep rserver

And then kill the offending processes:

# or more extreme
kill -9 <PID OF PROCESS>

I hope that helps! Please let us know if you keep running into trouble! We will do what we can to see if there is a way to reproduce this issue and prevent this type of thing from happening!
