Thank you for taking the time to report this issue and helping to make Ubuntu better.

This installation looks like it was caused by hardware problems (device sda). There are messages such as

I've marked this bug as incomplete (due hardware issues), if you believe I'm in error please leave a comment as to why, and you can return the status to "New".

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). If you're unfamiliar with these, I suggest seeking looking up refer to https://discourse.ubuntu.com/t/finding-help/709
