I attempted to install Fedora Workstation 40 for aarch64 systems on my Raspberry Pi 5, and it failed to install. It barely booted, then stopped at a “recovery” shell prompt. Not much else I can add to that. Fedora Workstation installs and works just fine on x86_64 systems, as I have it installed both on hardware and as a virtual machine. Works exactly as advertised. But I think that the Fedora developers really need to get with some Raspberry Pi 5 owners and hammer out a better version to work on that platform. Right now, as far as I’m concerned, Ubuntu 24.04 for Raspberry Pi is the best distribution you can install on the Raspberry Pi 5.
