[Bug 1861556] Re: g-ir-scanner doesn't work (so can't build gnome packages any more)

[Launchpad Bug Tracker]

This bug was fixed in the package gobject-introspection -
1.62.0-4ubuntu2

---------------
gobject-introspection (1.62.0-4ubuntu2) focal; urgency=medium

  * rules: Pass the private module directory to dh_python3. We only build for
    the default python version. Previously dh_python3 wasn't finding the
    directory containing the private modules, so it didn't know this. This
    meant that no versioned python3 dependencies were generated so we could,
    for example, be migrated without the corresponding version of python3
    migrating. That results in programs which don't run. Once the directory is
    passed, dh_python3 generates dependencies on the right python versions.
    For future transitions gobject-introspection will need to be binNMUed.
    See Debian #950267.
  * Uploading this to a PPA without focal-proposed and then binary copying to
    the real focal-proposed to hopefully let this migrate on its own, to
    unbreak g-ir-scanner in focal release. After this migrates, the plan is to
    do a no-change rebuild normal upload to focal-proposed to get a binary
    with the correct dependencies. (LP: #1861556)
