Comment 4 for bug 1875496

For future developers:

TRIAGE:

This may be a bug in layer-basic. The race is the dependent code not unpacked before it gets called.

Simple re-create steps:

charm pull cs:designate-38
cd designate
juju deploy ./tests/bundles/bionic_train.yaml
(wait for cloud to settle)

git clone https://github.com/openstack/charm-designate/
mv charm-designate designate
tox -e build
cd build/builds/designate
juju upgrade-charm --switch .

The charm will be in a hook error as described above.
