Resolution

1. Make a backup copy of /etc/foreman-installer/scenarios.d/satellite-answers.yaml
2. If /etc/foreman-installer/scenarios.d/satellite-answers.yaml has an entry "foreman_proxy::plugin::remote_execution::ssh:" remove it as well as inner parameters.

foreman_proxy::plugin::remote_execution::ssh:
  enabled: true
  listen_on: https
  generate_keys: "********"
  install_key: "********"
  ssh_identity_dir: "/var/lib/foreman-proxy/ssh"
  ssh_identity_file: id_rsa_foreman_proxy
  ssh_keygen: "********"
  local_working_dir: "/var/tmp"
  remote_working_dir: "/var/tmp"
  ssh_kerberos_auth: false
  async_ssh: false

3. Re run "satellite-maintain restore" command
