Unable to load VPN connection editor in Ubuntu 14.04 LTS

Some time ago I created a VPN connection using Ubuntus own Network Manager, which worked fine! Now, a few months later, I want to go in and edit the connections details, but instead I get this error: unable to load VPN connection editor.

Any idea how this could be solved?

[UPDATE] Starting the connection manager manually with nm-connection-editor lets you edit the settings, but that still leaves the original error.

Solution 1:

Run

sudo apt-get install openvpn network-manager-openvpn network-manager-openvpn-gnome

This will prompt for both your password, and a Y/n answer, please provide it with your password, and Y.

Solution 2:

If you use a vpnc connection, like with FritzBox routers, run

sudo apt install network-manager-vpnc network-manager-vpnc-gnome

Solution 3:

The answers are quite specific. What helped me was indeed:

1. Running nm-connection-editor from the terminal

2. The following warning gives you the hint to the missing dependency

Could not load editor VPN plugin for “org.freedesktop.NetworkManager.XYZ” (missing plugin file "/usr/lib/x86_64-linux-gnu/NetworkManager/libnm-vpn-plugin-XYZ-editor.so").

3. Install the missing dependency via sudo apt-get install network-manager-XYZ-gnome, i.e. using one of

• network-manager-l2tp-gnome
• network-manager-openconnect-gnome
• network-manager-pptp-gnome
• network-manager-vpnc-gnome
• network-manager-openvpn-gnome
• ...

With the missing /usr/lib/x86_64-linux-gnu/NetworkManager/libnm-vpn-plugin-XYZ-editor.so now installed on your system, the network editor will continue working like a charm.

Solution 4:

Try this:

sudo apt-get install network-manager-pptp-gnome
