I am not a technician, and the person who installed the package is disappeared. What could have been happened? Do I need to re-install it? I have no enough technical knwoledge to work on Ubuntu system, so I am looking for some professional help.
As an update, I received this comment on GitHub (https://github.com/instructure/canvas-lms/issues/2168#issuecomment-1459403837). As I said however I have no sufficient knowledge in how to work with servers, hence I am looking for somebody to hire for a consulting. The person who installed the app died few months ago and I have no idea how to see if Passenger is working correctly or not (following what said in the link above)
