You can build your own LTS image relatively easy and free of charge

The process is not straightforward, especially if you want to customize the image.

And I have been unable to build a cloud-init image.

But the ISO is buildable from the LTS branch and it works well.

It's been a while since I tried it, but I remember this roughly being my experience as well.

I'm usually all for up to date software, but on my networking equipment??? I don't really want to beta test that stuff, but that's what they seem to want to make me do.
