RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

When running packstack installation in a base Centos7 system, following error appears:

Version-Release number of selected component (if applicable):


How reproducible:

allways

Steps to Reproduce:
1. Enable RDO repositories in a RHEL 7.4 system.

cd /etc/yum.repos.d/
wget http://trunk.rdoproject.org/centos7/delorean-deps.repo
wget http://trunk.rdoproject.org/centos7/current-passed-ci/delorean-repo

2. install packstack

yum install -y openstack-packstack

3. run packstack allinone option

packstack --allinone

Actual results:

Installation fails with error:

  File "/usr/lib64/python2.7/site-packages/cryptography/hazmat/backends/__init__.py", line 7, in <module>
    import pkg_resources
ImportError: No module named pkg_resources



Expected results:

packstack command should run fine


Additional info:

File /usr/lib64/python2.7/site-packages/cryptography/hazmat/backends/__init__.py
is importing pkg_resource provided by python-setuptools but it's not included as dependency. I think that's a missing Requires.
Comment 4 Alan Pevec 2018-04-13 23:26:03 UTC 
Version-Release number of selected component: python2-cryptography-1.7.2-1.el7_4.1

FWIW pkg_resource was removed since upstream version 1.9
https://github.com/pyca/cryptography/commit/51032351297b9bf7d783b7138ac0c142d8e38918#diff-a2fa29b78aa32458ce597e791c8ac549
Comment 5 Christian Heimes 2019-02-26 16:47:16 UTC 
The problem has been resolved in RHEL 7.5 by https://access.redhat.com/errata/RHBA-2018:0720 . python-cryptography now correctly depends on python-setuptools.
