I've found that the biggest thing getting in my way of making things 'just work' is not being able to sude dnf install anything. Every time I try, I just get the prohibitive 'Fedora Atomic images utilize rpm-ostree instead' message. Is there a workaround to this? I've had a very difficult time installing anything that doesn't just come in a flatpak.
I know very little about Linux as a whole and have recently switched, so please be as basic as possible and assume I know nothing.
