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 Ronald Wahl 2011-03-14 16:41:09 UTC 
Description of problem:
pkcon does not work correctly - e.g. "pkcon repo-list" outputs only
Getting repositories          [=========================]         
Starting                      [=========================]         

Version-Release number of selected component (if applicable):
PackageKit-0.5.8-13.el6.x86_64

How reproducible:
always - when pygobject2 is not installed (its missing from requirements!)

Steps to Reproduce:
1. Install PackageKit
2. Make sure that pygobject2 is not installed
3. Call "pkcon repo-list"
  
Actual results:
Only some meta info and progress bars:

Expected results:
Meta info and progress bars + a list of repositories

Additional info:
The problem is just the missing requirement for pygobject2.

Additionally it would be clever to output an error message if something is missing. Strace showed me that there were some python tracebacks logged but I guess they just vanished somewhere.

I don't think PackageKit actually requires pygobject2 -- it's possible yum requires pygobject2, which PackageKit uses, but the added dep would belong in yum I think.

Can you get the output of pkcon --verbose without pygobject2 installed please -- I'm surprised there isn't a backtrace. Thanks.

Comment 4 RHEL Program Management 2011-04-04 02:08:38 UTC 
Since RHEL 6.1 External Beta has begun, and this bug remains
unresolved, it has been rejected as it is not proposed as
exception or blocker.

Red Hat invites you to ask your support representative to
propose this request, if appropriate and relevant, in the
next release of Red Hat Enterprise Linux.
Comment 5 Richard Hughes 2011-08-18 09:55:19 UTC 
Right, you're completely correct. I fixed the same bug in Fedora a few weeks ago. Adding a req for pygobject2 for PackageKit-yum is what we need to do.
