[Launchpad Bug Tracker]

This bug was fixed in the package probert - 0.0.20

---------------
probert (0.0.20) groovy; urgency=medium

  [ Ryan Harper ]
  * Run wrap-and-sort on debian dir
  * debian/control: Change probert-storage Architecture to any to allow
    binary arch dependencies
  * Add dasd files to probert-common and probert-storage install files
  * multipath: use non-whitespace to split output
  * Makefile: use python3 and be virtenv friendly
  * lvm: don't use vgscan --mknodes

  [ Michael Hudson-Doyle ]
  * cope with block devices with no MAJOR in udev
  * introduce and use a sane_block_devices helper that checks for MAJOR
  * fix tests, thanks ryan
  * have dry run mode supply some fake scan results

  [ Tsunghan Liu (Robert Liu) ]
  * Support CAN interfaces (LP: #1890397)

  [ Paride Legovini ]
  * d/control:
    - drop Build-Depends on pyflakes (not needed) (LP: #1879731)
    - drop Build-Depends on pep8 (not actually used)
    - set Rules-Requires-Root: no
    - bump the dh compat level to 13 via debhelper-compat
    - bump Standards-Version to 4.5.0 (no changes needed)
    - fix the bin packages short descriptions
    - drop the XSBC-Original-Maintainer field
  * d/rules:
    - drop the PYBUILD environment variables (not needed)
    - drop explicit dh_missing --fail-missing (default in compat >=12)
    - include pkg-info.mk instead of parsing d/changelog
    - build with DEB_BUILD_MAINT_OPTIONS = hardening=+all
    - drop the get-orig-source target
  * d/copyright: use the versioned format URI
