Issue

Cant edit vpn or create an vpn because the editor wont load, tried using nm-connection-editor
and the built in wifi tab from mint and neither of them worked.

nm-connection-editor gives error that it couldn't load /usr/lib/x86_64-linux-gnu/NetworkManager/libnm-vpn-plugin-l2tp-editor.so

Steps to reproduce
Get to the wifi section
add an new network
select L2TP VPN connection
error loading the vpn editor

Make sure you install the network-manager-l2tp-gnome package if you haven't already. The GTK 3 & 4 L2TP editor plugins are in that package.

cinnamon-control-center has an issue loading GTK 3 VPN editor plugins that are using NMACertChooser or NmaCertChooser, see issue #319.

network-manager-l2tp-gnome >= 1.20.18 have a fix for compatibility with cinnamon-control-center. You can obtain the latest version of network-manager-l2tp packages for Mint and Ubuntu from this PPA:
