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).

Description Lubos Kocman 2018-02-08 09:22:43 UTC 
Hello,

recent RHEL-7.5-Snapshot-3.0 compose failed on following https://brew.engineering.redhat.com/brew/taskinfo?taskID=15244771


I double checked lorax in builroot and in compose (the install repo) and it's the same version
[root@rcm-compose-nightly-01 ~]# brew latest-pkg rhel-7.5-build lorax

Since lorax itself wasn't touched I suspect one of packages in buildroot

Comment 2 Lubos Kocman 2018-02-08 09:27:15 UTC 
#list of packages changes in compose wasn't complete (I used same tail length as for buildroot). So this is a full list

# we're looking at changes since lates 6th+ as nightly on 6th at night succeeded.

Not a dupe, but seemed to be temporary issue,

https://brew.engineering.redhat.com/brew/taskinfo?taskID=15245518

resubmit of very same task later passed.
