[Bug 1861537] Re: installer crashes when it is "creating partitions" or "calculating files to skip copying"

[Chris]

Ok, thanks for reading this. I would like to point out that it doesn't happen when trying to install a few other distro's, like vanilla Ubuntu or Fedora. I have checked the integrity of the USB flash drive, and all seems well there, and I have also checked the integrity of my drive that I am installing to (works fine of course, and have check nvnme-cli just to read some of the stats).
  
  The only thing that I would think that it would be, is that the ISO is bad somehow... but I actually re-downloaded it when I did, because of this same error, thinking that downloading a new iso would work. 

  This same error occurs when I try to install KDE Neon, Kubuntu and
Xubuntu, but not vanilla Ubuntu.

Just to get the ISO out of the question, I will download a new one,
using torrents and retry, and then come back.

Title:
  installer crashes when it is "creating partitions" or "calculating
  files to skip copying"

Status in ubiquity package in Ubuntu:
  Invalid

Bug description:
  I believe that the installer crashes at the points listed in the
  title, but I cannot be for sure. But those are the things that it is
  saying at the time it crashes.

  If it is not listed, I am trying to install to a single NVMe drive,
  and it is the only one. I am able to install Ubuntu (vanilla), but
  Xubuntu and Kubuntu and KDE Neon do this same exact thing, with the
  same exact error.

  Xubuntu 19.10
