Houston, we have a problem.

I installed the new 1TB and 8TB SSDs and attempted to install Ubuntu 24.04
from the live USB stick I have been using so far. I went through the manual
installation steps, put the OS on the 1 TB drive and setup the 8TB drive,
and the installation crashed. The drives are brand new. I submitted a bug
report to Ubuntu - https://bugs.launchpad.net/subiquity/+bug/2121085. Not
sure if you can access that report to see if you know what happened. Any
suggestions? I will try it again and take screenshots of the
partition tables. Maybe I messed that up.
