I have an older System 76 laptop running 18.04 in a lvm across 2 disks (1 TB and 2 TB). I have backed up all the data, and would like to install 22.04 just on the 1 TB SSD, and then replace the 2 TB with a 4 TB and the backed up data (/home/mark).

I downloaded 22.04 desktop iso, verified it, installed it on a USB drive, and booted the USB drive. 22.04 comes up and I can "try" it. When I try to install it, I get as far as the 5th screen, Installation Type, where I select the 1 TB drive and hit continue. Nothing happens after that. I had selected normal installation, download updates, and erase disk. I know nothing is happening because after waiting 10 minutes on that screen, I can still boot into the old 18.04 installation, so the 1 TB drive has not changed. I did this multiple times with different iso downloads, different USB drives, and created the bootable USB on different computers.

Could this have anything to do with the lvm currently installed across the two drives? Should I go into the "try" part of the USB drive, open gparted, and reformat the two internal drives, then start the installation again?

All I have connected to the computer is power, an Ethernet cable (verified to be working), the USB boot drive, and a USB mouse (the internal trackpad is broken).

Thanks!

Mark
