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 Mai Ling 2022-04-19 13:27:11 UTC

Description of problem:
this is effectively https://bugzilla.redhat.com/show_bug.cgi?id=1393488 but on EL8

Version-Release number of selected component (if applicable):


How reproducible:
see https://bugzilla.redhat.com/show_bug.cgi?id=1393488

Steps to Reproduce:
1. see https://bugzilla.redhat.com/show_bug.cgi?id=1393488
2.
3.

Actual results:


Expected results:


Additional info:

I rent a low-budget low-resources vps loaded with an EL8 clone therefore I remove and disable anything that results in less memory and disk consumption. polkit is one of the hungry resources that I don't need.

pasted results before and after removing polkit. reproductible on latest official free developer EL8 iso, up to date.

This is not reproductible on EL9 beta; removing polkit has no negative effect on dbus logs.

Comment 1 Eric Garver 2022-04-21 13:20:27 UTC

Based on bug 1393488, this is actually a bug in python-slip.

It was fixed in commit fed1b05a1719 ("Fix org.freedesktop.DBus.Error.ServiceUnknown errors without polkitd"), but that commit was never part of any official python-slip release. As such the fix did not propagate to RHEL-8.

RHEL-9 is NOT affected because the python-slip dependency was dropped in firewalld v1.0.0.
