I've added a background image to /usr/share/backgrounds, but I'm not sure how to set it as the default wallpaper. I'm using Ubuntu with the Cinnamon desktop environment, and I'd like some guidance on this. Any help is appreciated, but please don't come at me with the usual "why are you doing this if you're new?"

If you're just looking for a quick fix, try right-clicking on your desktop and see if there's an option to directly set the wallpaper from there.
Another approach is to find the configuration file that sets the wallpaper and modify it. You can keep a copy of that adjustments in /etc/skel, so all new user accounts will start with the edited config.
You might want to try placing your image in /usr/local/share/backgrounds instead. The /usr/* directories are typically reserved for system package management, so that's probably why it's not working as expected.
Just putting an image in /usr/share/backgrounds won't automatically make it the default wallpaper. You need to change the settings in your desktop environment to select that image as your wallpaper.
