NetworkManager unable to store/edit vpnc, tab blank

Hello everybody,

since the last update I’m unable to add new vpnc-connections or edit existing ones.

Also, the VPN tab for new or existing vpnc connections is empty:

Starting the NetworkManager from the terminal gives me this output:

$ nm-connection-editor

The undefined symbol: nm_vpn_editor_factory_vpnc error is due to the nm_vpn_editor_factory_vpnc() function being unintentionally removed from NetworkManager-vpnc 1.4.0 source code. See the upstream bug report:

Hello and welcome,

If this feature is crucial to you then you might consider a downgrade.

sudo pacman -Syu manjaro-downgrade
sudo downgrade networkmanager-vpnc

You likely do not want to add the package to the ignore list when prompted, or else you will have to manually remove it later when the next update is available.

Note: Downgrading is usually a last resort and should not be performed lightly.

Thank you for the hint. I know that downgrading is a dirty fix, but I will have a look at the networkmanager-vpnc updates coming up.
