VOLTTRON reinstall master driver agent on 7.0

Question

On VOLTTRON 8.0 versions that use platform.driver I can reinstall the platform.driver with:

python scripts/install-agent.py -s services/core/PlatformDriverAgent -c services/core/PlatformDriverAgent/config -f --start --enable

But on VOLTTRON 7.0 versions that use master_driveragent how do I reinstall the master driver agent on 7.0?

If I do: python scripts/install-agent.py -s services/core/MasterDriverAgent -c master-driver.config -f --start --enable

This will throw an error: ERROR:install-agent.py:Force option specified without a target identity to force.

And if I leave out the force -f this will also throw an error:

Stderr:
b'install: error: Agent with VIP ID platform.driver already installed on platform.\n'
NoneType: None
Traceback (most recent call last):
  File "scripts/install-agent.py", line 387, in <module>
    install_agent(opts, opts.package, opts.config)
  File "scripts/install-agent.py", line 148, in install_agent
    out = execute_command(cmds, env=env, logger=log,
  File "/var/lib/volttron/volttron/platform/agent/utils.py", line 776, in execute_command
    raise RuntimeError()
RuntimeError

The current vctl status looks like this:

(volttron) volttron@volttron:/var/lib/volttron$ vctl status

The 7.0 install agent script is not aware of the default identity for the agent, so you have to provide it explicitly

add -i platform.driver

full install script:

python scripts/install-agent.py -s services/core/MasterDriverAgent -c master-driver.config -f -i platform.driver --start --enable
