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.

I'm not able to reproduce this problem any more (to get output now takes less than 10s)

Could you please check if it can't be the same problem that was fixed by:

+++ This bug was initially created as a clone of Bug #579262 +++

Description of problem:
Since the last PackageKit's update, PackageKit is very too slow to update (5-30 for download the meta-data, 5 minutes for display the updates then changelogs), and for start the update…

No problem with the composant for installation.
But with YUM, I download my updates with 350 ko/s


Version-Release number of selected component (if applicable):
PackageKit 0.5.7-2.fc12 x86_64


Network connectivity was ok. But I'm not able to reproduce problem. Could you please check if 



How reproducible:
Launch update with PackageKit

--- Additional comment from rhughes on 2010-04-03 15:27:36 EDT ---

Could you provide more details please? Is this reproducible?

--- Additional comment from cacouret on 2010-04-03 19:23:02 EDT ---

I have just to launch update with PackageKit to have this bug.
With my 2 machines, it's same.

More details ? The GNOME's sensors detect no network activity with my machines, but PackageKit say "Getting information" or "Download meta-data" and PackageKit not work correctly with it comportment…

--- Additional comment from rhughes on 2010-04-06 04:37:50 EDT ---

Is it as slow if you use "pkcon update" rather than the GNOME GUI tools?

--- Additional comment from cacouret on 2010-04-06 11:31:41 EDT ---

After « pkcon update », GNOME GUI PackageKit is faster, even after « yum clean all ».

I do not know why ...

--- Additional comment from rhughes on 2010-04-06 11:55:34 EDT ---

I think this was fixed in PackageKit 0.6.3:

Comment 1 Richard Hughes 2010-05-07 14:39:50 UTC 
It's probably a good idea to backport 95f29eab53e273f8b7824d878578ffe2e8770aba into RHEL6, agreed.

Hello I succeeded to reproduce similar problem and I caught output by strace (strace -p `pgrep pkcon` (hope it will help) see strace.txt

Comment 6 Lubos Kocman 2010-07-15 10:57:48 UTC 
Hello

I'm not facing this issue any more. I believe that It may be moved to verified as I did multiple actions via pkcon and no hangout appeared.

PackageKit-0.5.8-8.el6.x86_64
Comment 7 Lubos Kocman 2010-07-22 13:46:53 UTC 
Verified on PackageKit-0.5.8-8.el6


Hello I haven't faced to this issue for a long time. So moving to verified.

Thank you guys
