[Bug 1931146] Re: installer crash on manual partitioning when using encryption

[JT Moree]

This may be a duplicate of an eight year old bug
https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1510731.  The
workaround is to use the gtk_ui

1. Install ubiquity-frontend-gtk;
2. run "ubiquity gtk_ui"

options are not exactly the same but close enough to get install with
LUKS root.

!!!! Be aware that another bug causes the installer to RECREATE existing
LUKS partitions even if you CANCEL the install. DO NOT use ubiquity to
manage crypto partitions for an install of Kubuntu/Ubuntu on existing
LUKS partitions.  Instead, use luksOpen yourself before running
ubiquity.

Title:
  installer crash on manual partitioning when using encryption

Status in ubiquity package in Ubuntu:
  New

Bug description:
  I am attempting a fresh install on a dual boot setup.  currently using
  windows 10 and Kubuntu 20.04. I am also using LUKS but the installer
  doesn't really seem to support it--even the old manual setup-- so I
  might have to downgrade to 20.10.

  I have existing partitions so I choose manual but when I attempt to
  assign partitions and tell the system to format it crashes.  In this
  case I  was assigning /boot as a plain partition with nothing special
  and when clicking OK it crashes.  I don't even get to the Install Now
  button.  it crashes editing the /boot partition.
