We create pre-built Ubuntu Core images for several testing platforms. These images are a way to explore Ubuntu Core. Canonical produces official images for the following platforms.
We recommend first users try pre-built Ubuntu Core images in Raspberry Pi or Intel NUC, as these range of devices are easy to use and widely accessible.
Once you have downloaded the respective image, follow one of the next options:
Install Ubuntu Core using Raspberry Pi Imager
Use a graphical tool to simplify the process of flashing the Ubuntu Core to a storage medium. This method works on Windows, macOS, and Linux, and is accessible for users of all skill levels.
Install Ubuntu Core with the dd command
Use the dd command to write the Ubuntu Core image to the storage medium. This approach offers more precision and control over the flashing process but requires a higher skill level.

Hello, not sure if this is the right place. I’m trying to install Ubuntu Core in my Raspberry PI Zero 2W with the pre-built image of version 22 arm64. After burning the image to a SD card via Raspberry PI Imager, as it is recommended in the guide, I boot my PI with it but it’ll never finish the initial setup.
I’ve read in some forum that if I connected a keyboard and pressed ESC I’d see the logs for startup. Indeed, I see them, and I see this error message before they hang:
taskrunner.go:289: [change 2 “Setup system for run mode” task] failed: cannot install system: cannot mount “/dev/mmcblk0p4” at “/run/snapd/gadget-install/dev-mmcblk0p4”: invalid argument
It came right after some “created new partition /dev/mmcblk0...” logs.
I’ve tried both by downloading the 20, 22 and 24 images from the referred website and straight from the Imager software, result would be the same. Only the line number of the error changes. I haven’t found anything about this error elsewhere. Do you have any suggestions?
