dbus Ubuntu18 64 bit

[andrey_and]

I'm trying to create a dbus connection. First request the name of the bus:

Code: Pascal  [Select][+][-]

1. ret := dbus_bus_request_name(conn, 'my_server', DBUS_NAME_FLAG_REPLACE_EXISTING, @err);

Getting an error:

Connection ":1.68" is not allowed to own the service "plus.piramida.server" due to security policies in the configuration file

In terminal

dbus-daemon --system

also error:

Failed to start message bus: Failed to bind socket "/var/run/dbus/system_bus_socket": Address already in use

In Ubuntu 32 bit all good.
Where should I look, tell me, please.
