[Bug 1935969] Re: Ubuntu 20.04.2 LTS installer crash when letting the system determine size of additional LV

[Michael Hudson-Doyle]

Are you enabling encryption in the guided screen? This sort of bug means
we are mis-estimating how large the VG is going to be and we've had a
few bugs like this in the past but I thought they were mostly fixed. The
.crash file from /var/crash would be great help in figuring out what is
going on.

Title:
  Ubuntu 20.04.2 LTS installer crash when letting the system determine
  size of additional LV

Status in subiquity package in Ubuntu:
  New

Bug description:
  Tested on VMware ESXi 6.5/6.7

  Trying to install a VM using the graphical installer and using i.e. a
  60GB disk, letting the system autoprovision the required partitions
  naturally creates a VG on the entire disk, and an LV of roughly 50% of
  the VG size. If you then create a secondary LV on the same VG and do
  not fill in the size of the LV, the system should claim all remaining
  space. However, this causes the installer to crash, not instantly, but
  a few seconds after having confirmed the partition layout (when you
  are on the user creation part of the install).

  Lowering the size of the additional LV by as little as ~500MB solves
  the issue and the installer runs just fine through everything.
