Good morning all,

We’re moving from our old xcat installation (2.14.2, CentOS 7)  to a new 
cluster running Ubuntu 22.04 with xcat 2.16.5, and I’m hitting a snag trying to 
build the initial image.   The xcat install itself seems fine –

lsxcatd -v
Version 2.16.5 (git commit b588632f2fa62f34e658f2f0b1d12ad07201f981, built Fri 
Mar  3 09:07:25 EST 2023)

The first problem was that there was no .pkglist file for ubuntu22 in the 
/opt/xcat/share/xcat/netboot/ubuntu directory, so I copied the file for 
ubuntu20 and tried genimage again, but it keeps erroring out.

genimage -o ubuntu22.04.2  -m  ubuntu20.04_compute01
  OS: ubuntu22.04.2
Available Profiles for ubuntu22.04.2:
   cbsu
   compute
   cudafull
   cudaruntime
Which profile do you want to use for ubuntu22.04.2?  [cbsu ] compute
  Profile: compute
OPTIONAL: Which specific network interface will the image boot from? [<blank>]
  No interface specified.  The interface will be determined at network boot 
time.

There’s a rootimg where I expect it, but no ramdisks.  It feels like I’m 
missing something obvious, but neither my notes from a few  years ago or 
anything I can find in the documentation is helping me see what I’m missing ...

Can anyone point me in the right direction?
