The autobuild log of the failure is available here:

The failure seems to be in the "samba-nt4" suite, whose build logs are available here:

    python/samba/tests: make sure samba.tests can be imported without SamDB
    We are using samba.tests Python module file as a catch-all
    for all types of helpers. Some of these helpers are only usable with
    Samba AD DC targets.
    When SamDB is not available in a non-Samba AD DC target, provide a
    dummy replacement that simply returns None. This allows to complete
    initialization for non-Samba AD DC target tests which do not use
    connect_samdb() helper.
