[Bug 1746992] Re: [SRU] gnocchi-api in Bionic uses python3, and libapache2-mod-wsgi-py3 conflicts with the python 2 version

[James Page]

This bug was fixed in the package gnocchi - 4.2.4-0ubuntu3~cloud0
---------------

 gnocchi (4.2.4-0ubuntu3~cloud0) bionic-rocky; urgency=medium
 .
   * New update for the Ubuntu Cloud Archive.
 .
 gnocchi (4.2.4-0ubuntu3) cosmic; urgency=medium
 .
   * Enable alternative python2 dependencies for gnocchi-api (LP: #1746992):
     - d/control: gnocchi-api depends on libapache2-mod-wsgi-py3 by default and
       libapache2-mod-wsgi as an alternative. gnocchi-api also depends on
       gnocchi-common, which depends on python3-gnocchi by default and
       python-gnocchi as an alternative.
     - d/control: move all other python run-time dependencies to
       python(3)-gnocchi packages.
     - d/control: Add Conflicts to python(3)-gnocchi binary to ensure both
       can't be installed at the same time.
     - d/control, d/tests/*: Enable autopkgtest-pkg-python testsuite and drop
       obsolete XS-Testsuite: autopkgtest header.
     - d/tests/*: Add Python 2/3 autopkgtests for gnocchi daemons and shebangs.

Bug description:
  Since the two wsgi modules are conflicting, installing gnocchi-api
  breaks other OpenStack services.

  [Impact]
  Installation of gnocchi-api (which is currently py3 only) on the same machine as other OpenStack services that are py2 only causes conflicts. libapache2-mod-wsgi-py3 and libapache2-mod-wsgi conflict with each other.

  [Test Case]
  Ensure cinder-api (py2 only atm) and gnocchi-api (with new py2 alternatives) can be installed on the same machine.

  [Regression Potential]
  Low. This doesn't make any changes to the existing py3 version of gnocchi-api. It only adds alternatives that enable a py2 version of gnocchi-api.
