[Bug 1920656] Re: loading Lubuntu 18.04 crashed when I removed the flash drive prematurely

[Chris Guiver]

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

This installation looks like it was caused by a corrupted file system,
or device problems (sdb & sdb5). I notice in the logs

Your description also provides for it being a user-created error
condition.

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), and possibly the integrity of your partition table
(https://help.ubuntu.com/community/Smartmontools). If you're unfamiliar
with these, I suggest seeking support, options available can be seen at

Title:
  loading Lubuntu 18.04 crashed when I removed the flash drive
  prematurely

Status in ubiquity package in Ubuntu:
  Incomplete

Bug description:
  I had wanted to create a start-up disk on a Flash Drive, but what I
  thought was the process of installation on my hard drive was actually
  being installed on the Flash Drive. I removed the Flash Drive before
  the process was complete. That was when the Crash Notice appeared.
