Hello,

Discussed with infra(#opendev)

Issue started after: https://review.opendev.org/c/openstack/project-config/+/872476/2

we stopped installing python-dev nd python-xml, either of which would have pulled in python2.7

~~~
<clarkb> I think we have ~3 options: A) revert/or readd python2-dev installs B) ask projects to fix their broken bindep.txts (something we've asked for for years at this point) or C) update -py27 jobs to explicitly install python2 for you

We also merged https://review.opendev.org/873020 about twenty
minutes ago, so as of 22:12:13 any jobs inheriting from
openstack-tox-py27 will automatically install the python and
python-dev (old Python 2.7) packages.

But definitely still put Python interpreters in your bindep.txt
files, they're useful if for no other reason than to indicate to
anyone looking at the file that your project needs those.

I have proposed a fix for the above issue: https://review.opendev.org/c/openstack/openstack-zuul-jobs/+/873056.

[Sandeep Yadav (sandeepyadav93)]

This issue got fixed after infra included the installation of py27 in pre-steps [1] and fix [2]. But it's good to mention it in bindep.txt[3] as well.

[OpenStack Infra (hudson-openstack)]

This issue was fixed in the openstack/tripleo-heat-templates train-eol release.
