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.

Updating against a satellite with RHN enabled, as well as an HTTP repo of RHEL6 files. Running without '--changelog' seems to do the trick, but anyway - traceback is not nice.

Comment 2 James Antill 2010-12-15 16:06:21 UTC
  File "/usr/lib/python2.6/site-packages/yum/update_md.py", line 312, in
__init__
    self.add(repo)
  File "/usr/lib/python2.6/site-packages/yum/update_md.py", line 398, in add
    for event, elem in iterparse(infile):
  File "<string>", line 64, in __iter__
SyntaxError: mismatched tag: line 129, column 2

...this means that the updateinfo for the repo. is not XML. We already do:

        for event, elem in iterparse(infile):
            if elem.tag == 'update':
                try:
                    un = UpdateNotice(elem)
                except UpdateNoticeException, e:
                    print >> sys.stderr, "An update notice is broken, skipping."
                    # what else should we do?
                    continue
                self.add_notice(un)

...but we could certainly move that out to cover the iterparse too. --changelog/--security/etc. still won't _work_ (because that data is broken), but it won't traceback.

Comment 3 David Kovalsky 2010-12-15 16:17:04 UTC
Hi James,
thanks for the quick reply. 

It'd be nice to have such a solution. Printing something like "WARNING: changelog data won't be available, format is wrong" would clearly points users the right direction.
