Seems to be this part here (in proxy/installer/rhn-proxy-activate.py)

   s = getServer(options, DEFAULT_WEBRPC_HANDLER_v3_x)
    systemid = getSystemId(cfg)

    errorCode, errorString = 0, ''

    try:
        if not s.proxy.is_proxy(systemid):
            # if system is not proxy, we do not need to deactivate it
            return (errorCode, errorString)
    except:  # pylint: disable=W0702
        # api do not have proxy.is_proxy is implemented or it is hosted
        # ignore error and try to deactivate
        pass
    try:
        s.proxy.deactivate_proxy(systemid)       # proxy 3.0+ API
    except:  # pylint: disable=W0702
        errorCode, errorString = _errorHandler()
        try:
            raise
        except xmlrpclib.Fault:
            if errorCode == 8:
                # fine. We weren't activated yet.
                # noop and look like a success
                errorCode = 0
            else:
                errorString = "WARNING: upon deactivation attempt: %s" %
errorString
:

I think, the main problem is, that "is_proxy()" cannot be called (throws
an error, at least, if there really is no proxy with that systemID).

Thus,

s.proxy.deactivate_proxy(systemid)

get's called. I cannot find this code ("deactivate_proxy"), except in
this script, thus this might also throw an exception.

But this is all speculative. I cannot test this "proxy" activation here.

"is_proxy" can also be found in

java/code/src/com/redhat/rhn/common/db/datasource/xml/System_queries.xml


<mode name="is_proxy">
  <query params="sid">
SELECT  1
  FROM  rhnProxyInfo PI
 WHERE  PI.server_id=:sid
  </query>
</mode>
