Validated against Xenial and Artful, while IBMCloud doesn't have any publicly available artful images, we've contrived an example upgrade from public xenial instance to artful to ensure it doesn't break.

=== END SRU Validation Xenial ===


=== BEGIN SRU Validation Artful ===
IBM Cloud only provides Ubuntu at LTS versions, so there is no
artful image that we can launch. Thus, this test is a bit contrived
and the bug is quite unlikely to affect a user there.
