Unable to save password

[stdex]

Hello.

This problem marked in wiki as "fixed": https://github.com/nm-l2tp/NetworkManager-l2tp/wiki/Known-Issues#unable-to-save-password

But I can't confirm this. In my case, if I use mode "Request this password every time" and try to connect - this not working, a window with a choice of a password is not displayed, in log I can see message: "Invalid VPN service type (cannot find authentication binary)".

This problem is definitely not related to l2tp, I find simalair mark about it in openvpn (https://necromuralist.github.io/posts/openvpn-on-ubuntu-1804/), but I would like to find solution without save password or use nm-applet as connection manager. Could you please confirm the existence of such a problem at the moment with you?

My configuration: Ubuntu 20.04 Linux 5.4.0-18-generic GNOME Shell 3.35.91 network-manager 1.22.10-1ubuntu1 network-manager-l2tp 1.2.16-1 network-manager-l2tp-gnome 1.2.16-1

I've just installed the latest Ubuntu 20.04 focal-desktop-amd64.iso in a VM. I'm not able to reproduce the issue.

I'm not running nm-applet, but am running the same version of gnome-shell as you.

I've also tested using the nmcli command line, in the below the id can be found by looking at the output of nmcli con.

1. test connection with "Request this password every time" set :

$ nmcli con up id "Test VPN"
You need to authenticate to access the Virtual Private Network 'Test VPN'.
Warning: password for 'vpn.secrets.password' not given in 'passwd-file' and nmcli cannot ask without '--ask' option.

Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/1)

A dialog box popped up asking for the password.

2. test connection with "Request this password every time" set and --ask command-line switch :

$ nmcli con up id "Test VPN" --ask
You need to authenticate to access the Virtual Private Network 'Test VPN'.
Password: (vpn.secrets.password): •••••••••••••••
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/2)

3. test connection with "Store the password for all users" set :

$ nmcli con up id "Test VPN"
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/3)

The GNOME Secret Service is used to store the password. Could you try using secret-tool to do a lookup of the password using the VPN connection's UUID and see if you get any Secret Service error.

$ nmcli con
NAME                UUID                                  TYPE      DEVICE 
Wired connection 1  f0a21a1d-d96d-3bf9-8e59-230f682c03c2  ethernet  ens33  
Test VPN            e7102e5e-8b0c-4f18-8a14-02c18943d0b3  vpn       -- 

$ secret-tool lookup connection-uuid e7102e5e-8b0c-4f18-8a14-02c18943d0b3
this-is-the-actual-password

EDIT: the secret-tool lookup example only works if "Store the password for this user" is used.

Yes, after restart it started to work for me too.
I do not know what this may be connected with, possibly with the update gnome.
