Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
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 Orion Poplawski 2016-10-27 15:21:38 UTC 
Description of problem:

I'm seeing this with /etc/cron.hourly/0yum-hourly.cron:

Traceback (most recent call last):
  File "/usr/sbin/yum-cron", line 729, in <module>

    if self.skip_if_unavailable and self._metadata_cache_req in ('write', 'read-only:future'):
AttributeError: 'YumRepository' object has no attribute '_metadata_cache_req'

This appears to be triggered by an issue with my local mirror:

# yum makecache

http://epel.cora.nwra.com/7/x86_64/repodata/repomd.xml: [Errno -1] Error importing repomd.xml for epel: Damaged repomd.xml file

but a better error message would be nice.

Version-Release number of selected component (if applicable):
yum-cron-3.4.3-148.el7.noarch
Comment 2 Valentina Mukhamedzhanova 2016-11-02 11:03:12 UTC 
I believed this is fixed in yum-3.4.3-150.el7.
Comment 3 Orion Poplawski 2016-11-04 03:54:24 UTC 
Looks like it.  I can't reproduce it with that version.
