VPN connection failed because there were no valid secrets

[Frindli]

I wasn't any problem with vpn before OTA 14. And I haven't any problem NOW on desktop ubuntu. Then I tried reset the vpn connection details with ubuntu touch network manager or the VPN editor click package (pete woods) but vpn don't worked from gui.

If I type in the terminal app "sudo nmcli con up VPNNAME" the message is: A password is required .. Warning: password for 'vpn.secrets.password' not given in 'passwd-file' and nmcli cannot ask without --ask option. I give again and again the correct password on the gui but dont work after ota 14..
And on Ubuntu Touch not worked for me if I tried the openvpn from terminal (sudo openvpn xy.conf).

Now, the connection is done successfully but only from terminal with this:
sudo nmcli --ask con up VPNNAME

I confirm this problem. It seems to have appeared at sone tine after (but not immediately with) release of OTA-14.
Although VPN configuration has not changed, I cannot establish VPN connections via system indicator or system settings. Sliding the switch immediately displays the massage: Connection failed, because there was no valid configuration data.
I have tried re-entering the password in VPN settings, even deleting connection data and re-creating it via system settings, to no avail.
As Frindli correctly describes, the VPN connection can be established from the terminal, using
sudo nmcli con up VPNNAME
But this asks for the VPN password. So it appears that the password is not stored any longer when creating the VPN configuration using system settings.
As said before, this used to work until late 2016.

I confirm this as well. Using Nexus 4 with OTA-15.04 this does't work any longer. Used to work fine with cyberghostvpn as of this instruction: http://askubuntu.com/questions/754878/how-to-setup-openvpn-provided-with-ota10-on-ubuntu-touch

password doesn't seem to be stored since it does not even try to establish the connection but fails immediately.

Many thanks

I also have problem connectiong with VPN from gui

I got similar problem in openSUSE Tumbleweed and found out that openvpn package was upgraded to version 2.4 but my openvpn configs were created for version 2.3.
Openvpn 2.4 is incompatible with old configs, so you should either rewrite conflicting parameters to the new format or downgrade openvpn package to 2.3.*.
