unfortunatly UKI is not working because we try to install apt-get download linux-modules-extra-6.16.0-16-generic ci and it's missing from the system. If I do a quick check I see that the only extra modules package is linux-modules-extra-6.14.0-1002-realtime which of course doesn't map with the hwe kernel in the system and break kairos init.

from listing the modules after installing the 24.04 hwe kernel I do see some nvdimm, @Itxaka would this be enough?
