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.

The main package already has a versioned dependency on the avahi-libs subpackage, which is alright. But the dependency in the opposite direction is wrong.

This problem has been corrected on Fedora 20+, but the correction needs to
be backported to RHEL-7.

Minor specfile only change. Proposing for RHEL-7.2 fastrack. Unfortunately it is too late for RHEL-7.1.

Comment 19 Laszlo Ersek 2015-03-14 00:05:01 UTC 
I don't know how this bug was fixed, but avahi is completely un-upgradeable from 0.6.31-13.el7 to 0.6.31-14.el7, with yum.

Error: avahi-libs conflicts with avahi-0.6.31-14.el7.x86_64
Comment 20 Laszlo Ersek 2015-03-14 00:09:47 UTC 
By that I mean that apparently one has to force-remove avahi, before upgrading the libraries (and then optionally reinstalling avahi):

# rpm --erase --nodeps avahi
Comment 21 Michal Sekletar 2015-03-16 11:51:16 UTC 
Can you please provide a list of avahi packages on your system and yum error output when you try to upgrade avahi?
Comment 22 Laszlo Ersek 2015-03-16 12:09:23 UTC 
I'm sorry, I can't reproduce those errors any longer. I worked it around as described in comment 20. The update I tried to exec was from 0.6.31-13.el7 to 0.6.31-14.el7.

That said, I've seen this kind of error with other (independent) packages at other times. If there is an incorrect circular dependency between packages, and that cycle is broken in a later spec update, I guess it might not be possible to perform update at all, without manually breaking the cycle first in the installed rpmdb.

BTW: while I was googling for a prior report, I found bug 1199462. That report seems to capture a very similar (if not exactly same) update error, except it seems to attribute the error to gnome-shell-browser-plugin. In my case, gnome-shell-browser-plugin was nowhere around, I just got the avahi conflicts that are listed in bug 1199462 comment 0,
Comment 23 Laszlo Ersek 2015-03-16 12:09:48 UTC 
Sorry, that should have been a period (.). I don't have anything else to add.
