[Bug 1824457] [NEW] Grub problem forced re-install, resulting in crash (see http://paste.ubuntu.com/p/RjjrVvBwSs/)

[Howard Oates]

Public bug reported:

In the reinstall, I selected 'manual' for disk setup, set /dev/sda7 to
format as ext4 at /, then selected /dev/sda8 to be set as /home/ with
ext4 type. After returning to the partition layout screen I decided I
should wipe what is in the /home partition in case something there is
causing the grub problem. At the point I clicked on the 'format' check
box the system crashed and requested I file a bug report.

No syslog or partman files can be seen in /var/log/installer/

I booted from a USB stick written with with the kubuntu 18.4.2 LTS iso
downloaded from  https://kubuntu.org/getkubuntu and written to USB using
ddrescue from the command line.
