Verified.
Tested on Satellite 6.12.0 Snap 12.0
Version: python3-gofer-2.12.5-8.el9sat.noarch
Steps:
1. Setup Satellite 6.12, Enable/Sync dogfood EL9 client repo and register a RHEL9 host
2. Verify EL9 client repo is enabled and this on RHEL9 client
# grep -nR is_alive /usr/lib/python3.9/site-packages/gofer/agent/plugin.py
304: return self.scheduler.is_alive()
3. Install katello-agent and check the status of goferd on the RHEL9 host
Observation:
katello-agent install works and goferd is in running state after install on EL9 host, Package install via katello-agent worked.
Additionally, I tested EL7 and EL8 content hosts with this fix for renaming "isAlive" to "is_alive" is done, and they also worked fine.

Description of problem: Python 3.9 has renamed the isAlive() method to is_alive(). RHEL 9 runs on Python 3.9 but the gofer package we ship via satellite-client-6-for-rhel-9-x86_64-rpms repo, It still contains the isAlive() method. # grep -r isAlive /usr/lib/python3.9/site-packages/gofer/ grep: /usr/lib/python3.9/site-packages/gofer/agent/__pycache__/plugin.cpython-39.opt-1.pyc: binary file matches grep: /usr/lib/python3.9/site-packages/gofer/agent/__pycache__/plugin.cpython-39.pyc: binary file matches /usr/lib/python3.9/site-packages/gofer/agent/plugin.py: return self.scheduler.isAlive() Version-Release number of selected component (if applicable): Satellite 6.11 and 6.12 RHEL 9 python3-gofer-2.12.5-7.1.el9sat.noarch How reproducible: Always Steps to Reproduce: 1. Install a Sat 6.12 or 6.11 2. Sync satellite-client-6-for-rhel-9-x86_64-rpms in satellite 3. Connect a RHEL 9 client with the satellite. 4. Enable the satellite-client-6-for-rhel-9-x86_64-rpms repo on the RHEL 9 host 5. Install katello-agent on the RHEL 9 host 6. Check the status of goferd on the RHEL 9 host.
