Bugzilla: 2354980 – Unable to install Fedora CoreOS on Raspberry Pi 3B+ using arm-image-installer
After trying CoreOS in virtual machines I thought I’d put it on my Raspberry Pi 3B+. I expected the installation procedure to be the same, that I could use arm-image-installer to install CoreOS on the MicroSD card. This didn’t work however as I got an error during the installation.
- I downloaded the latest Fedora CoreOS release for aarch64: fedora-coreos-41.20250302.3.2-metal.aarch64.raw.xz
- I inserted the microSD card and tried to install it using the same command that I’ve used for Fedora Server:
sudo arm-image-installer --image=/home/mikaeldui/Downloads/fedora-coreos-41.20250302.3.2-metal.aarch64.raw.xz --target=rpi3 --media=/dev/mmcblk0 --addkey=/home/mikaeldui/.ssh/id_ed25519.pub --resizefs - Everything went well until I got this error:
mount: /tmp/fw: wrong fs type, bad option, bad superblock on /dev/mmcblk0p1, missing codepage or helper program, or other error.
dmesg(1) may have more information after failed mount system call.
Error: mount /dev/mmcblk0p1 /tmp/fw failed
There’s a guide for installing CoreOS on a Raspberry Pi 4, but I have a Raspberry Pi 3B+: Provisioning Fedora CoreOS on the Raspberry Pi 4 :: Fedora Docs
