ubuntu:22.04 should work just fine though.
Those are the official Ubuntu images which are different from the community images.

It may be a bad cache or index file at the time, doing lxc image info ubuntu:22.04 would be useful to see if the issue still persists or was resolved. If that commands work, then it means it’s the cache being bad, which can be flushed manually to resolve this.

My bad, I always defer to images: (and copy them locally)
What Stéphan suggested works from here.

not a related post, when I clicked the new topic under LXD, got a message that ‘you are not allowed to create topics in this category’, why?

LXD is no longer part of the Linux Containers project, as a result, this forum is no longer the place for support on it.

Hey. Is this command: ubuntu:22.04 is equivalent to this: ubuntu/22.04/cloud ?

Yeah, those images are roughly equivalent, ubuntu/22.04/cloud is missing snapd and a few other small things, but it is an Ubuntu image with cloud-init enabled similar to ubuntu:22.04.
