SSH schlechte Besitzerberechtigungen
This started popping up immediately after I created another user with Administrator privileges,
and that account began inheriting access to my .ssh folder.
You do not need to change your permissions whatsoever.
Just go to .ssh, right-click Properties, Security Tab, Advanced.
DISABLE INHERITANCE, then click on the Administrator user (the one that is not you) and Remove them. Apply. Done.
