Thank you for taking the time to report this issue and helping to make Ubuntu better.
This installation looks like it was caused by a corrupted file system, or device problems. I notice in the logs (there are loads of errors, this is just a snippet) Apr 24 09:38:38 ubuntu kernel: [ 2530.275499] sd 0:0:0:0: [sda] tag#5 Sense Key : Medium Error [current] Apr 24 09:38:38 ubuntu kernel: [ 2530.275505] sd 0:0:0:0: [sda] tag#5 Add.

I suggest you validate the health of your hardware (esp. disk by checking it's SMART status using `smartctl`, `gnome-disks` or whichever tool you prefer), and possibly the integrity of your partition table (https://help.ubuntu.com/community/Smartmontools).
