I’m not able to create a new container with rockylinux/10 or almalinux/10.
root@rapper:~# incus launch images:rockylinux/10 r10
Launching r10
root@rapper:~# incus ls r10

Same happens when I create a container with almalinux/10.
It works OK for rockylinux/9 or almalinux/9.
My Incus server is 7.2, host OS is Ubuntu 24.04, storage driver is zfs.

Can you check incus console --show-log r10?

Ah. Interesting
root@rapper:~# incus console --show-log r10
Fatal glibc error: CPU does not support x86-64-v3
Same for almalinux

Yeah, RHEL 10 and derivatives have moved to an x86-64-v3 baseline, so any machine older than 2013 or so will not be able to run it.

This is on a system with a Intel(R) Pentium(R) Gold G6405 CPU @ 4.10GHz, which I’m hoping it supports that instruction set.
If I’m correct I have to wait until I have upgraded Ubuntu 24 LTS→26 LTS [1]. In august I can do a do-release-upgrade. I’ll report back when that’s done.

I looked up your CPU and it seems it doesn’t support avx or avx2, seems you won’t be happy with any v3 distro.

Indeed, you’re right

Bummer. I only bought this system 18 months ago. No wonder that it was “cheap”, ha ha.

Anyway, I’ll have to stick with rocklinux/9 then.
