Hi I run Sudo dpkg-reconfigure resolvconf which did not help, but I deleted the line dns=dnsmasq in /etc/NetworkManager/NetworkManager.conf I still obtain the message of the sort ,---- | [TDE NM Backend ERROR] | [/tmp/buildd/tdelibs-trinity-14.0.4~pre12/tdecore/tdehw/networkbackends/network-manager/network-manager.cpp:1823] | Attempting to access the network-manager VPN service returned: | org.freedesktop.DBus.Error.ServiceUnknown: The name | org.freedesktop.NetworkManager.VPN.Plugin was not provided by any | .service files [TDE NM Backend ERROR] | [/tmp/buildd/tdelibs-trinity-14.0.4~pre12/tdecore/tdehw/networkbackends/network-manager/network-manager.cpp:1823] | Attempting to access the network-manager VPN service returned: | org.freedesktop.DBus.Error.ServiceUnknown: The name | org.freedesktop.NetworkManager.VPN.Plugin was not provided by any | .service files `---- but it does connect! However the icon does not change to the usual connect sign (while in my other with kubuntu 14.04/trinity everything works smoothly) I tried sudo dpkg-reconfigure network-manager-tde did not really work, I can disable wireless but I cannot switch to offline and then back to online mode, the icon looks that if there is only offline activated. I really don't want to reinstall but this is quite a bit annoying. Thanks Uwe Brauer
