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.

Description Jason Woods 2022-04-07 12:27:51 UTC 
Description of problem:

Since release of python-s3transfer-0.1.13-1.el7_9.2.noarch some utilities, such as certbot from EPEL, no longer function, as well as some internal applications.

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

python-s3transfer-0.1.13-1.el7_9.2.noarch

How reproducible:

Always

Steps to Reproduce:
1. Update to python-s3transfer-0.1.13-1.el7_9.2.noarch
2. Run following:

$ python
>>> import boto3
>>> import urllib3
>>> urllib3.__file

3. Also run the following:

$ python
>>> import urllib3
>>> import boto3

Actual results:

1.

    from urllib3.util.ssl_ import (
ImportError: cannot import name PROTOCOL_TLS

Expected results:

Previous version, python-s3transfer-0.1.13-1.el7.0.1.noarch, would return working, as follows. Note that the urllib3 is not replaced from fence-agents and is working.

Additional info:

Seems like new version has bundled new urllib3 of version 1.26.8 - much higher than the system one of 1.20.2 - but if the system one is already imported before boto3, which is case in my apps and certbot, then it ends up with 1.20.2 which seems to break boto3
Comment 3 Jason Woods 2022-04-07 12:48:07 UTC

Comment 4 Jered Floyd 2022-04-19 03:50:28 UTC 
Duplicating my comment from rhbz#2050751, this also breaks the package "awscli-1.14.28-5.el7_5.1.noarch":

# aws --version

Comment 9 Henning Schmiedehausen 2022-07-11 00:46:08 UTC 
confirmed when using python-s3transfer-0.1.13-1.el7_9.2.noarch and certbot-1.11.0-2.el7 (which uses python 2.7)
