I am setting up Cisco VPN on Ubuntu 12.04, when I run into strange behavior. I have downloaded and installed the following packages: vpnc network-manager-vpnc and dependencies.

When adding the connection with network manager, I am not able to save the connection - I only get this error

VPN error

I have tried different settings, tried importing cisco .pcf without any luck so far.


While searching for solutions, I have stumbled upon a way to restart the network manager applet:

killall nm-applet; nm-applet &

This did not solve my problems, but I noticed that a log is written to the terminal after running the command, and I think it may tell something (no idea what, though!)

After clicking save, these lines are written in the terminal:

(nm-applet:4079): GLib-GIO-CRITICAL **: g_async_initable_real_init_finish: assertion `g_simple_async_result_is_valid (res, G_OBJECT (initable), g_async_initable_real_init_async)' failed

** (nm-applet:4079): CRITICAL **: dbus_g_error_has_name: assertion `error != NULL' failed

(nm-applet:4079): GLib-CRITICAL **: g_error_free: assertion `error != NULL' failed

Useful suggestions here Config import on network-manager-openvpn which helped me to establish that my problem (same symptoms as above) are down to the network manager and not openvpn itself.

Had the same problem & just fixed it. I've installed gnome3 using ricotz's ppa. Before I had some problems with gnome-shell-extensions so I've downgraded it to gnome3-team ppa packages (maybe it takes a part). To fix nm problem I've downgraded libglib2.0-0 from ricotz's version to precise-updates. I've made this by synaptic (package->force version), but I think cli version is

sudo apt-get install libglib2.0-0/precise-updates
