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 of problem:

compose-id is CentOS-Stream-9-20220126.0

After last compose CS9 promotion, BaseOS/AppStream repos seems broken:

Comment 1 Alfredo Moralejo 2022-01-27 09:27:34 UTC 
Issue seems similar to https://bugzilla.redhat.com/show_bug.cgi?id=2021809

Issue may be related to picking different mirrors for different repos:

If i force to use the same mirror for both repos it seems to work fine.

IMO, there is something wrong with the way we sync and pick mirrors.
Comment 2 Adrian Reber 2022-01-27 09:55:26 UTC 
Should be fixed 20 after the hour. This is the known problem of scanning the primary mirror for changes while it is being updated.

This scan was triggered by the COMPOSE_ID in SIGs telling that there are changes in 'SIGs/'. The scan, however, happened during a time that '9-stream/' was being updated so that we scanned the primary mirror while files are being copied to the primary mirror which resulted in an incomplete scan.

This is known and we still have not implemented a fix currently.
Comment 4 Alfredo Moralejo 2022-01-28 14:36:51 UTC 
Similar issue today for CentOS Stream8:

Error: 
 Problem: cannot install the best candidate for the job
  - nothing provides libgcc >= 8.5.0-8.el8 needed by gcc-8.5.0-8.el8.x86_64
  - nothing provides libgomp = 8.5.0-8.el8 needed by gcc-8.5.0-8.el8.x86_64
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

As this is CentOS Stream 8 it does not really belong in this ticket as the backend systems are different.
