Expected Behavior

provisioning to succeed

Steps to Reproduce

attempt to provision litmusimage/centos:stream9 using docker

Environment

• c36abcfc6469278910c34b063d0e1fc98e4e93cc
• centos stream 9

Additional Context

The failure points to provision/tasks/docker.rb:38 in install_ssh_components; start there and inspect how the Docker provisioner creates SSH host keys for CentOS Stream 9. Reproduce with the litmus:provision_list[default] task and confirm provisioning succeeds without the unsupported DSA-key command.
