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 sgardner 2021-07-09 13:26:00 UTC 
Description of problem:

- Having configuration 'ShowPatchLevel no' in  /etc/ssh/sshd_config will break sshd in RHEL8.
- This should be an inhibitor for the leapp upgrade process


How reproducible:
- EASY - Every Time

Reproducer:
~~~
1. Add 'ShowPatchLevel no' to /etc/ssh/sshd_config
2. complete leapp preupgrade  (no mention of configuration issue)
3. Complete leapp upgrade to RHEl8.4  (no inhibitor)


Actual results:
- not recognized as an issue.
- Once booted into RHEL8, sshd will fail due to deprecated configuration.


Expected results:
- Leapp to identify this configuration as an inhibitor - similar to other sshd inhibitors.
Comment 14 Petr Stodulka 2021-10-20 13:23:27 UTC 
The check / inhibitor has been implemented and merged in the upstream:
  https://github.com/oamg/leapp-repository/pull/695

It's going to be part of the next release.
