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.
