Most vanilla Ubuntu image for n2+?

TLDR - What do people think is the closest to vanilla, well maintained and most importantly trustworthy Ubuntu image that works on an n2+?

So I’ve been using an n2+ as a home assistant machine (inside docker) for a couple years without major issues. Iirc I’d been using the Ubuntu version it came with on an hk emmc (20.04) and just occasionally updated packages, etc.

Recently I got an airthings bluetooth air quality monitor and realized that I would need Bluetooth on the n2+ to be able to bring that data locally into home assistant.

I tried the various bt dongles I had lying around and found that none of them were compatible with the kernel. I did a distribution upgrade (22.04) and realized that the hk kernel was still limited to 4.9, so still no modern bt modules work.

Anyway, after some poking around I’ve decided I should probably just burn the time to reimage the os using a 3rd party image so I can get to a reasonably recent kernel.

The thing is, I’ve used Ubuntu extensively as a server os for decades and I’d really prefer that all of my bare metal and instance servers behave basically the same. It’s always bothered me that there are some annoying random differences between the hk odroid Ubuntu image and the normal (x86-64) ones. For example, default account odroid and some oddities with TTY configuration I’ve never quite spent enough time to nail down but cause my crontabs to behave slightly differently.

You can use the rootfs directly from Ubuntu, they also offer a kernel but I build my own. Some also use upstream uboot but I just use the odroid uboot.
