I am trying to add auditing and logging of rstudio console commands in my rstudio server that is installed on an Ubuntu machine. But whatever I add in the /etc/rstudio/rserver.conf file (I tried two different settings) and then restart the server by sudo rstudio-server restart the following error is thrown,
IO error reading /etc/rstudio/rserver.conf: unrecognised option 'audit-r-console'
