I don't see any errors about being able to read the disk, or that ubiquity even crashed. What I do see is your log spammed full of lines like this: May 26 20:55:51 ubuntu systemd-udevd[16997]: Process 'hid2hci --method=dell --devpath=/devices/pci0000:00/0000:00:1a.0/usb3/3-1/3-1.2/3-1.2:1.0' failed with exit code 1. May 26 20:55:51 ubuntu upowerd[1500]: unhandled action 'unbind' on /sys/devices/pci0000:00/0000:00:1a.0/usb3/3-1/3-1.2/3-1.2:1.0
