Title:
  shrinking previous file systems makes them corrupted

Status in e2fsprogs package in Ubuntu:
  New

Bug description:
  Booted in UEFI mode, running test example 'Install (auto-resize) in
  Kubuntu Desktop amd64 in Bionic Daily' the previous file system was
  shrunk in order to create space for the current one. But it was
  corrupted and must be fixed.

  Workaround: sudo e2fsck -f /dev/sda2

  The same thing happened when booted  in UEFI mode, running test
  example 'Install (manual partitioning) in Kubuntu Desktop amd64 in
  Bionic Daily'

  Workaround: sudo e2fsck -f /dev/sda3

  (This current operating system's file system was fixed and made
  bootable again.)
