cannot import name 'ugettext_lazy' from 'django.utils.translation'

[Corey Bryant]

On Ubuntu Mantic, the dashboard fails to load and the apache error log shows:

It looks like the charm template needs updating to work with Django 4.x in Mantic.

See upstream commit in horizon:

    Address RemovedInDjango40Warning (2)

    django.utils.translation.ugettext(), ugettext_lazy(), ugettext_noop(),
    ungettext(), and ungettext_lazy() are deprecated in favor of the
    functions that they’re aliases for: django.utils.translation.gettext(),
    gettext_lazy(), gettext_noop(), ngettext(), and ngettext_lazy().

== Ubuntu SRU Details ==

[Impact]
magnum dashboard can't be used with Django 4.x.

[Test Case]
Deploy openstack with magnum + magnum-ui. Ensure dashboard is functional and no errors in /var/log/apache/error.log.

[Regression Potential]
This is a pretty simple change to aliased functions and regression testing mentioned above should be good enough to ensure behavior is as expected. Currently the dashboard doesn't work on Mantic where Django is at 4.2.4. This package is backported to the Bobcat cloud archive on Jammy where Django is at 3.2.12 and will need testing there, however should be fine considering these functions were deprecated in Django 3.0.

[Corey Bryant (corey.bryant)]

Hi Steve, I just wanted to make sure you saw the [Test Case] section in https://bugs.launchpad.net/cloud-archive/+bug/2039226/comments/3. I should have probably put that in the Description, just didn't want to polute the upstream bug. Or did you want more details in the [Test Case]? Thanks for taking a look!

leave the extra debugging output out of the description, but the SRU info still belongs there
