___________________________________ summary ____________________________________
ERROR: py27: commands failed
Appears that a new version of stestr (3.0.0) was release Mar. 26 and does not support py27.
https://pypi.org/project/stestr/#history
https://pypi.org/project/stestr/3.0.0/
stestr v2.x.x release series will be the last series that supports Python 2. Support for Python 2.7 was dropped in stestr release 3.0.0.
We'll need to use an earlier version for py27 tests.
I hit this in starlingx/fault but this may impact other starlingx repos that use py27 and stestr.
Note: many of the starlingX repos use upper constraints from stein, which caps at 2.2.0
