Bug Description

In 22.04 I am unable to create a new VPN in network manager and nm-connection-editor. After filing in the entire form the save button remains disabled!

watching the terminal provides this error:
Cannot save connection due to error: Invalid setting General: connection.interface-name: '': interface name must not be empty

Seems like the form validator is not looking at the right field!

This also affects the UI connection manager! I merely provided the nm-connection-editor error as you get no error in the UI, the Apply button just remains disabled.

This is a NetworkManager bug. It happens in the GNOME applet and in nm-connection-editor.

Also reproduces in Fedora 36 Beta 1.

I am affected as well on Arch Linux. Seems related to NetworkManager-vpnc version 1.2.8 - when I downgrade that package to 1.2.7-dev everything works fine.

I can confirm the bug running a brand new Lubuntu 22.04, with package network-manager-vpnc-gnome version 1.2.8-2.

Running nm-connection-manager on a terminal, trying to add a new connection, Cisco Compatible VPN (vpnc), we can see the following message on terminal after filling all the fields:

Cannot save connection due to error: Invalid setting General: connection.interface-name: '': interface name must not be empty

There is also the same hint on the disabled Save button.

With this message in mind, I just found a workaround: click "Advanced", fill the Tunnel interface name with tun0, click Apply. There is also a bug here because even then the Save button is still disabled, but if you click "Advanced" again and Apply, the Save button is finally enabled and you can Save the connection.

I do not know why the tunnel interface would be required and if it really is, this field should be placed in the main form, not in the advanced window. However, I guess it should be still an optional field.

The workaround is possible, on Ubuntu Gnome, only by editing the connection with Advanced Network Configuration (nm-connection-editor) and not the main Gnome Settings application.

Workaround mentioned by Dave Chiluk, doesn't work for me.
Adding an VPN using nm-connection-editor from a terminal does work, but I still cannot activate it using the grome-network-manager. They don't appear at all in the network manager.
