I’m sorry to hear that you’re having a hard time getting the software running. I understand that this can be very frustrating.
As others have said, making yourself the owner of everything can cause numerous issues in the long run and there’s a reason why most distributions DON’T make you root.
Why are you using Linux in the first place? I think sonarr and jackett both run on Windows as well.
Don’t let the frustration get the best of you. If you really want to run those tools yourself, then dive into it (and all the technical issues that are part of it), but if you only want to have access to the functionality, you might want to look into a service that takes care of all the technical burden.
