Bug Description

Binary package hint: network-manager-openvpn

When I try to import a VPN connection from an openvpn file that works on the commandline, the definitions load just fine, but I can not save it unless I enter the password for the key. Quite ridiculus, why should I need to save the password?

If I manually enter a VPN definition I can save the configuration without entering the password but trying to start it I get an error message about not being able to get the credentials (I would have expected a password prompt).

In syslog I find:
Jun 9 09:46:59 cray NetworkManager[1002]: <info> Starting VPN service 'openvpn'...
Jun 9 09:46:59 cray NetworkManager[1002]: <info> VPN service 'openvpn' started (org.freedesktop.NetworkManager.openvpn), PID 5677

This all used to work fine before. That behaviour started to show up in Ubuntu 64bit 10.10 with XFCE and is still present in Xubuntu 11.4 (32bit).

I can confirm the same bug, Even if you try to save the password the next time you open the VPN connection the passwrod is not there. Also you cannot find the password in the keyring.

Not sure if it is related to NM, openvpn or even dbus.

Looks like it is related to dbus configuration for the various network-manager plugins.

It seems the at_console config is missing :
working /etc/dbus-1/system.d/nm-openvpn-service.conf

This Bug has been there for quite some releases and is also present in networkmanager under Gnome (Unity). Comment #4 fixes the problem.

Changed in network-manager-openvpn (Ubuntu):
status: New → Confirmed

Had the same problem running fresh install of 11.04 Unity. Added at_console policy, which solved it for me. Can connect to OpenVPN.

This config is just plain wrong. The fact that such a workaround fixes things has nothing to do with the actual problem, so please don't break your system by applying such suggestions.

In most cases, simply *rebooting* after installing a VPN plugin will fix this; if not, then you really should add more information as to what exactly happens *as* the connection is being imported; without even activating it before adding the info to this bug report. Ideally this would be done by starting nm-connection-editor from the command-line so as to get all the messages from .xsession-errors.

Also, all the issues here should be fixed in Oneiric soon (preparing an upload that includes secrets fixes); there is a slight difference in how passwords are saved in the keyring which should allow you to choose whether to save them immediately in the config, get asked every time, or just "not needed".

Hello,

I'm using precise and also have the problem when connecting via ssh to the system, I can't bring the VPN up.

elyas:~$ nmcli con status id Capitar-VPN
Error: 'Capitar-VPN' is not an active connection.
elyas:~$ nmcli con up id Capitar-VPN
Error: Connection activation failed: Not authorized to control networking.
elyas:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu

Also I'm unable to edit the VPN settings when I run nm-connection-editor via the ssh link.
