[xml/sgml-pkgs] Bug#973283: libxml2 autopkgtest-virt-lxc failure on arm64 by python2 dependency

[Ryutaroh Matsumoto]

Source: libxml2
Version: 2.9.10+dfsg-6.1
Severity: normal

Usertags: py2removal

Dear Maintainer,

autopkgtest-virt-lxc fails on arm64 as follows.
(I used Raspberry Pi 4B running latest Debian testing).

Broken autopkgtest-satdep:arm64 Depends on python-libxml2:arm64 < none @un H >
  Removing autopkgtest-satdep:arm64 because I can't find python-libxml2:arm64
E: Unable to locate package python-libxml2
build                FAIL badpkg
blame: libxml2
badpkg: Test dependencies are unsatisfiable. A common reason is that your testbed is out of date with respect to the archive, and you need to use a current testbed or run apt-get update or use -U.

Complete log of autopkgtest is attached as zip file.

Best regards, Ryutaroh Matsumoto

The below is a template message of python2 removal:

Python2 becomes end-of-live upstream, and Debian aims to remove
Python2 from the distribution, as discussed in
https://lists.debian.org/debian-python/2019/07/msg00080.html

Your package either build-depends, depends on Python2, or uses Python2
in the autopkg tests.  Please stop using Python2, and fix this issue
by one of the following actions.

- Convert your Package to Python3. This is the preferred option.  In
  case you are providing a Python module foo, please consider dropping
  the python-foo package, and only build a python3-foo package.  Please
  don't drop Python2 modules, which still have reverse dependencies,
  just document them.
  
  This is the preferred option.

- If the package is dead upstream, cannot be converted or maintained
  in Debian, it should be removed from the distribution.  If the
  package still has reverse dependencies, raise the severity to
  "serious" and document the reverse dependencies with the BTS affects
  command.  If the package has no reverse dependencies, confirm that
  the package can be removed, reassign this issue to ftp.debian.org,
  make sure that the bug priority is set to normal and retitle the
  issue to "RM: PKG -- removal triggered by the Python2 removal".

- If the package has still many users (popcon >= 300), or is needed to
  build another package which cannot be removed, document that by
  adding the "py2keep" user tag (not replacing the py2remove tag),
  using the debian-python at lists.debian.org user.  Also any
  dependencies on an unversioned python package (python, python-dev)
  must not be used, same with the python shebang.  These have to be
  replaced by python2/python2.7 dependencies and shebang.

  This is the least preferred option.

If the conversion or removal needs action on another package first,
please document the blocking by using the BTS affects command, like

  affects <bug number of blocking py2removal bug> + src:gwyddion

If there is no py2removal bug for that reverse-dependency, please file
a bug on this package (similar to this bug report).

If there are questions, please refer to the wiki page for the removal:
https://wiki.debian.org/Python/2Removal, or ask for help on IRC
#debian-python, or the debian-python at lists.debian.org mailing list.
