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 Richard W.M. Jones 2012-12-04 16:38:08 UTC 
I hit the following stack trace on RHEL 6.4:

Traceback (most recent call last):
  File "<string>", line 39, in <module>

    yumdb_cache=self.yumdb_cache)
AttributeError: 'RPMDBAdditionalData' object has no attribute 'yumdb_cache'

If I'm not mistaken, this appears to be a variant of bug 730793.
The fix for this seems very simple and self-contained, and is already
part of the yum 3.2 branch.

--- Additional comment from Mads Kiilerich on 2011-08-15 15:37:02 EDT ---

This happened while /var/lib/rpm needed recovery. Yum should however not fail this bad. Ordinary yum commands run by root failed nicely.

Fixed in upstream, closing.

    Initialize RPMDBAdditionalData object even when makedirs /var/lib/yum/yumdb
Comment 1 Richard W.M. Jones 2012-12-04 18:50:52 UTC 
OK I have now verified that this really is a bug which
affects libguestfs builds in RHEL 6.4.
Comment 2 RHEL Program Management 2012-12-14 08:11:48 UTC 
This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.
Comment 3 James Antill 2013-04-22 18:11:09 UTC 
Simplish backport for 6.5, to repeat:

commit 2f480e8dd6757cbe48037a5507c0c19cc97b2e71
Author: Zdeněk Pavlas <zpavlas>
Date:   Tue Aug 16 13:13:12 2011 +0200
Comment 6 RHEL Program Management 2013-10-14 00:11:58 UTC 
This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated
in the current release, Red Hat is unable to address this
request at this time.

Red Hat invites you to ask your support representative to
propose this request, if appropriate, in the next release of
Red Hat Enterprise Linux.
Comment 14 Robin Lee 2014-09-23 03:25:54 UTC 
This issue does not occur if /var/lib/yum/yumdb exists, even the directory is not writable by current user.
Comment 16 errata-xmlrpc 2014-10-14 04:36:14 UTC
