Am working in Django and was trying to serve media files and was encountering an error with accessing the system folder serving media files. Being (much) less familiar with terminal-related commands, I searched SO for a solution. I ended up executing the "good" code in this SO answer. This part, specifically:
sudo groupadd varwwwusers
sudo adduser www-data varwwwusers
sudo chgrp -R varwwwusers /var/www/
sudo chmod -R 770 /var/www/
This somehow messed up my whole system. I can't even start gunicorn now, I'm getting OSError: [Errno 13] Permission denied: '/apps/djangoProjectFolder'
in my terminal output when I try to do so.
I'm basically clueless at this point. Would like to learn what I did wrong, and how I can undo this situation.
