Mi conexión VPN no me funciona en una instalación limpia de Kubuntu 15.04, y estaba en 14.10 y versiones anteriores. Puedo configurar una conexión a través del "editor de conexión", pero cuando quiero conectarme aparece una ventana que probablemente es donde debo escribir las contraseñas (pero desaparece inmediatamente, así que no puedo decirlo). Después de decir un rato que se está conectando, se da por vencido. Syslog se ve así:
grep NetworkManager /var/log/syslog

Crear una conexión con las contraseñas en la configuración tampoco ayudó: 9 de julio 16:46:17 nombre de host NetworkManager[811]: [1436453177.020663] [vpn-manager/nm-vpn-connection.c:1778] get_secrets_cb(): No se pudo solicitar los secretos de VPN n.º 2: (6) No había agentes disponibles para esta solicitud.
Intenté crear manualmente un archivo conf, lo que pareció funcionar parcialmente. ifconfigTenía un elemento adicional llamado tun0, podía hacer ping a sitios web usando URL, pero no podía cargar ningún sitio web en mi navegador. Esto podría ser una indicación de que mi problema es similar alÉste, pero no del todo, porque no tener sitios web funcionando es toda una restricción. Esto es lo que hice allí:
user@hostname:~$ sudo vpnc-connect /etc/vpnc/my_vpn_config.conf
[sudo] password for user:
Enter IPSec secret for [email protected]:

kvpncDa error: Timeout while connecting to 123.123.123.123. vpnc connect process will be killed.ping a la puerta de enlace y regresa dentro de 50 ms.
No estoy muy seguro de qué más probar. Otras opciones (pptp, openconnect, openvpn) parecen requerir un certificado de CA, que no tengo, así que supongo que estoy atascado con vpnc. ¿Ojalá alguien tenga algunas ideas?
Editar:parece ser una variante deeste error, aunque la solución no funcionó para mí.
