Red Hat Satellite engineering is moving the tracking of its product development work on Satellite 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 "Satellite project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs will be migrated starting at the end of May. 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 "Satellite project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/SAT-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.

Comment 1 Brad Buckingham 2021-08-19 15:03:17 UTC

Is this for specific repositories?
Is this only for a particular manifest?
Do the repositories get enabled despite the error message?

Thanks!

Comment 2 Ashish Humbe 2021-08-19 16:36:36 UTC

This is not specific to any repository set, when we try to expand the repository set then we see the below messages in the logs.

Comment 5 Justin Sherrill 2021-08-31 16:48:13 UTC

I'm suggesting we move this off of 6.10 for these reasons:

1. Its easily reproducible on 6.8 and 6.9 (not a regression)
2. This only adds some errors to the logs, scanning the repository causes no issues
3. It only happens with certain content sets, such as 'rhel-7-server-extras-rpms'


Steps to reproduce:

1.  import a manifest
2.  go to the RH repos page, scan repos for the 'rhel-7-server-extras-rpms' content set
3.  Notice you see no errors, and see the repository as expected.  You can enable it with no issue
4.  Check /var/log/foreman/production.log for errors, notice the errors mentioned here.

Thanks for the reproducer details Ganesh!

Comment 7 Justin Sherrill 2021-08-31 16:50:38 UTC

Comment 11 Sam Bible 2022-04-29 19:44:16 UTC

Verified on:
