Nextcloud (or docker for that matter) are rather complex.

Permission problems are every day life in linux, you always have to sudo or - if you change that - someone else can vaporize your server and steal all your data. Linux is infinitely more secure because it is a nightmare to use casually with a complex setup. Some windows script kiddie is gonna die inside your directories and never be found again.

Writing a script that you need to make executable first? Chowning files that are made by docker? Having to use a specific user inside docker (in case of nextcloud especially)?

All these things are incredibly frustrating but given the sheer complexity of nextcloud, it’s actually working rather good imo. So does linux.

I‘m not shitting on linux, docker or nc. I love them all but saying they’re not working just says they’re not plug and play yet. Other examples: most things snap are a mystery for me. Freakin permissions.
