Hope all is well....
I have tried to use this very command, but having issues with it not working.
sudo usermod -g daemon bitnamiftp
What I am trying to do is similiar to this ticket. Meaning when a file or something is downloaded within the site it is downloaded onto the site as bitnami:daemon.
the error I receive is:
sermod: user 'bitnamiftp' does not exist
Any chance you know what is going on?
