Non-Raspberry PI Hardware

What gotchas can I expect if I migrate to Ubuntu on Intel (Celeron) hardware?

Ubuntu 22.04 is very fresh. Docker has a track record of being weirdly slow to support new OS releases, even if the software is perfectly compatible. You may need to override your /etc/apt/sources.list.d/docker.list file to still use focal (20.04).

The switch in processor architecture (ARM → AMD64) should not cause any issues. We support both out of the box, and snapshots do not include processor-specific data.

Thanks. I’ll probably do 20.04 to be safe.

Are there any issues with changing the hostname after install?

None that I can think of. We don’t do anything special with the hostname, and the mandatory post-change reboot reset any system services that may be impacted.
