SOLVED: Linux user access issues

[Fate]

Well first I would remove any mention of a torrent client in your first post. (Maybe take a minute or two as well to read the forum rules)

To your issue, create a group (lets call it datamod for example)
put your user, jellyfin, any other app that should write to your media files in that group

Then run:
chgrp datamod /home/HappyCharizard/ -R

Then allow the grp to change stuff:
chmod 770 /home/HappyCharizard/ -R

Edit: eh seems TDP is even faster editing than I'm typing...


Thinking about this TDP is right, using your home directory will probably work but is a bad idea.
Move your data to /media/ /opt/  or something
