Bug description:
  [Impact]

   * lsblk no longer prints a partition's parent
     kernel device name (the wholedisk).
     (i.e., 'lsblk -no PKNAME /dev/partition')

   * Another impact is the 'removable media' check
     always return zero for partitions.
     (i.e., 'lsblk -no RM /dev/partition')

   * The regression was introduced on v2.34, only
     Eoan (v2.34) and later are affected.
     Disco (v2.33) and earlier are not affected.

   * The regression is fixed in v2.35, in commit
     e3bb9bfb76c1 ("lsblk: force to print PKNAME
     for partition"); fixes RM for partition too.

  [Test Case]

   * $ lsblk -no PKNAME /dev/vda1 # partition

   * Expected output: vda # wholedisk

   * Current output: (nothing)

   * $ lsblk -no RM /dev/sdb1 # partition in removable disk

   * Expected output: 1 # removable media

   * Current output: 0 # not removable media

  [Regression Potential]

   * Columns that depend on a partition device's
     parent device (i.e., seen as 'wholedisk')
     could in theory show incorrect values if
     another bug is present in v2.34 for that.

   * Other usages of 'parent' pointer in the
     function have been examined and reported
     (e.g. issue w/ removable media column),
     and others found to not have issues
     (e.g. --merge option, to group multiple
     parents of a device, as in RAID.)

  [Other Info]

   * The impacts to the curtin source package
     have been addressed in other way, it no
     longer requires util-linux, comment #14.

   * util-linux github issue:
     https://github.com/karelzak/util-linux/issues/813

  [Original Bug Description]

  During an install of the daily live image for 20.04 Ubuntu Server, the
  installer first crashed and restarted itself, then failed to install
  the system.

  Attached are the logs left on the install USB key.
