This bug was fixed in the package ubuntu-dev-tools - 0.178

---------------
ubuntu-dev-tools (0.178) unstable; urgency=medium

  [ Dan Streetman ]
  * pullpkg: also catch and deal with InvalidPullValueError. LP: #1908770

  [ Mattia Rizzolo ]
  * d/control: Bump Standards-Version to 4.5.1, no changes needed.
  * ubuntu-archive-assistant/mir: Fix a SyntaxWarning.
  * backportpackage:
    + Add a -e/--message option to change the default "No-change"
      in "No-change backport to DIST".
      Thanks to Unit 193 for the initial patch.

  [ You-Sheng Yang ]
  * Add a dependency on tzdata, used by mk-sbuild.

  [ Logan Rosen ]
  * import-bug-from-debian:
    + Limit bug description length to 50k chars to support Launchpad's limits.
      LP: #1193941

  [ Dimitri John Ledkov ]
  * pullpkg.py: fix --mirror option parsing.
  * config.py: add UBUNTU_INTERNAL_MIRROR option, for launchpad internal
    mirror.
  * archive.py: use Regular, Ports, and Internal mirrors by default. Thus
    enabling pull-lp-debs to work with ports architectures, and inside
    launchpad builds too.

  [ Michael R. Crusoe ]
  * pbuilder-dist:
    + Use `arch-test` to determine whether the current system can run binaries
      of the requested architecture, instead of hardcoding an ever-growing
      list of whether something requires qemu or not. Add the "arch-test"
      package to Recommends to that effect.

This bug was fixed in the package ubuntu-dev-tools - 0.193ubuntu4~20.04.2

---------------
ubuntu-dev-tools (0.193ubuntu4~20.04.2) focal; urgency=medium

  * ubuntutools/misc.py: back out a change that's incompatible with python
    3.8 to fix a build failure.

ubuntu-dev-tools (0.193ubuntu4~20.04.1) focal; urgency=medium

  * Backport current ubuntu-dev-tools to focal. LP: #2021910.
    - downgrade debhelper-compat dependency to 12 from 13 for focal
      compatibility.
    - this fixes compatibility with newer debootstrap which drops using
      per-Ubuntu-series symlinks for the bootstrap script. LP: #2020530.

ubuntu-dev-tools (0.193ubuntu4) mantic; urgency=medium

  * Remove references to ftpmaster.internal. When this name is resolvable
    but firewalled, syncpackage hangs; and these are tools for developers,
    not for running in an automated context in the DCs where
    ftpmaster.internal is reachable.

    unconditionally. LP: #2017177.

ubuntu-dev-tools (0.193ubuntu1) lunar; urgency=medium

  * Set apt preferences for the -proposed pocket in mk-sbuild so that
    it works as expected for lunar and forward.

  * Don't run linters at build time, or in autopkgtests. (Closes: #1031436).

ubuntu-dev-tools (0.192) unstable; urgency=medium

  [ Benjamin Drung ]
  * sponsor-patch:
    + Ignore exit code 1 of debdiff call.
    + Use --skip-patches instead of --no-preparation with dpkg-source -x.
  * Demote bzr/brz from Recommends to Suggests, as nowadays git is the way.
    Closes: #940531
  * Use PEP440 compliant version in setup.py (LP: #1991606)

  * Replace deprecated optparse with argparse
  * requestbackport: Remove useless loop from locate_package
  * reverse-depends: Restore field titles format
  * test: Fix deprecated return value for test case
  * Fix all errors and warnings found by pylint and implement most refactorings
    and conventions. Run pylint during package build again.
  * Bump Standards-Version to 4.6.2
  * Drop unneeded X-Python3-Version from d/control

  [ Masahiro Yamada ]
  * mk-sbuild:
    + Handle the new location of the Debian bullseye security archive.
      Closes: #1001832; LP: #1955116

  [ Mattia Rizzolo ]
  * requestbackport:
    + Apply patch from Krytarik Raido and Unit 193 to update the template and
