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.

Patch to fix whiteout.py and blacklist.py

Description of problem:

If you use a repo during installation (even if you dont install any packages from this repo) where groups.xml is gzipped, the whiteout.py and blacklist.py yum plugins cause anaconda to crash, as they do not handle compressed metadata.

Yum in general handles this fine - it's just these two plugins that fail.

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

anaconda-13.21.195-1.el6

How reproducible:

Always


Steps to Reproduce:
1. Create a valid repo using compressed metadata that contains package groups.
2. Verify that groups.xml is gzipped
3. Use this repo within anaconda
  
Actual results:

Anaconda produces an error with a stack trace.


Expected results:

Anaconda works fine.


Additional info:

I've attached a patch for whiteout.py - blacklist.py needs the same changes applied.

This Bugzilla has been reviewed by Red Hat and is not planned on being addressed in Red Hat Enterprise Linux 6, and will be closed. If this bug is critical to production systems, please contact your Red Hat support representative and provide sufficient business justification.
