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.

enter image description here

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.

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.

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

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

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").

  1. 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.

On Ubuntu 20.04 it was network-manager-openconnect-gnome:

sudo apt install network-manager-openconnect-gnome

I have had a similar issue on Ubuntu 18.04 which persisted after installing all the dependencies listed in other answers.

Starting nm-connection-editor from terminal logged the warning below

** (nm-connection-editor:8495): WARNING **: 19:18:23.811: Could not load editor VPN plugin for “org.freedesktop.NetworkManager.l2tp” (missing plugin file "/usr/lib/x86_64-linux-gnu/NetworkManager/libnm-vpn-plugin-l2tp-editor.so").

and the answer to that was

sudo apt install network-manager-l2tp-gnome
sudo service network-manager restart

as given in How do I connect to L2TP over IPsec using Network Manager?.
