Garnome 2.20.0 - System Administartion

["Thomas" <thomasgibson 27westfield freeserve co uk>]

I am a new user of Garnome and a long time user of Slackware. Can anyone
give me some idea on how to get the System->Administration tools to work.
e.g network-admin.
When I try these I get:-
"The configuration could not be loaded"
"You are not allowed to access the system configuration"
The system log file shows:
"Liboobs WARNING The name org.freedesktop.SystemToolsBackends was not
provided in any .service files"

Thankyou in advance
