  3. Stop solus-agent service:

    # systemctl stop solus-agent

  4. Create backup of the existing binary:

    # cp -a /usr/local/solus/bin/agent ./agent_orig

  5. Replace the binary with the customized one:

    # unzip agent.zip
    # cp -a agent.x86_64 /usr/local/solus/bin/agent
    # chmod 755 /usr/local/solus/bin/agent

  6. Start solus-agent service:

    # systemctl start solus-agent

  7. Start restoration of backup.
