I am receiving this error when I attempt to install via the manager, but I am able to install via Terminal. That said I am getting an option to install for either System or User, which I haven’t previously seen. I’m sure this is probably something pretty basic, but I’m fairly Linux illiterate… beyond knowing I can mess things up by fiddling without knowing what I’m doing.
I am on Nobara 37, Gnome 43.2, Wayland. I’d love a hand with this, thanks!
Edit: Thanks for the detailed answers! Issue resolved.
