Red Hat Satellite engineering is moving the tracking of its product development work on Satellite 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 "Satellite project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs will be migrated starting at the end of May. 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 "Satellite project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/SAT-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.

Comment 2 Brad Buckingham 2017-11-30 22:32:44 UTC 
This appears to be an issue on 6.2 as well; therefore, while could be a bug in Satellite, it appears to be being triggered by a change in the CDN content.
Comment 3 David Davis 2017-11-30 22:52:39 UTC 
It looks like this line is throwing the exception:

https://github.com/pulp/pulp_rpm/blob/10cb4e59b0ff80904e4704a73ff5e3fdb4762860/plugins/pulp_rpm/plugins/importers/yum/repomd/updateinfo.py#L88

This code has existed since 2012. I'm guessing the cause is the updateinfo.xml file has a 'reference' in pkglist without an href.
Comment 4 David Davis 2017-11-30 23:24:33 UTC 
Looks like the culprit is RHSA-2017:3315.
Comment 6 David Davis 2017-12-01 01:30:45 UTC 
Content Delivery team reports the problem has been fixed and I was able to successfully sync 'Red Hat Enterprise Linux 7 Server RPMs x86_64 7Server'.
Comment 7 Mike McCune 2017-12-01 02:11:33 UTC 
Propose we close this as NOTABUG as it was an issue with the CDN
Comment 8 David Davis 2017-12-01 13:41:24 UTC 
Tested the sync against Satellite version 6.3.0 beta.
Comment 9 David Davis 2017-12-01 14:10:28 UTC 
Looks like release engineering has a bug open that should prevent this from happening again:

https://bugzilla.redhat.com/show_bug.cgi?id=1466322

I opened a bug in upstream Pulp to make it more resilient and/or provide better logging when parsing repo metadata:
