Comment 49 for bug 1789177

The autopkgtest failures [1] on this seem unrelated as they are failing to importoslo.versionedobjects and there is no oslo found. This same failure occurs on python-oslo.versionedobjects without using the new python-oslo.messaging from proposed and a later (Groovy) version of python-oslo.versionedobjects has updated debian/tests/python-import to handle the import differently; specifically, the Bionic version is:

set -e

for py in $(py3versions -r 2>/dev/null) ; do
    cd "$AUTOPKGTEST_TMP"
    echo "Testing with $py:"
    $py -c "import oslo.versionedobjects; print(oslo.versionedobjects)"
done

and the Groovy version is:

#!/bin/sh

set -e

MODULE_NAME=$(python3 setup.py --name | sed 's/\./_/g')

for py in $(py3versions -r 2>/dev/null) ; do
    cd "$AUTOPKGTEST_TMP"
    echo "Testing with $py:"
    $py -c "import $MODULE_NAME; print($MODULE_NAME)"
done

The big difference to call out is that the groovy version replaces the dot ('.') after oslo with an underscore for the module import.
