Minha conexão VPN não está funcionando para mim em uma instalação limpa do Kubuntu 15.04, e foi em 14.10 e versões anteriores. Eu posso configurar uma conexão através do "editor de conexão", mas quando eu quero conectá-lo pisca uma janela que é provavelmente onde eu deveria digitar as senhas (mas se foi imediatamente, então eu não posso dizer). Depois de dizer por um tempo que está conectando, desiste. O syslog se parece com isso:
grep NetworkManager /var/log/syslog

Criar uma conexão com as senhas na configuração não ajudou: Jul 9 16:46:17 Nome de host NetworkManager [811]: [1436453177.020663] [vpn-manager / nm-vpn-conexão.c: 1778] get_secrets_cb (): Falha ao solicitar segredos de VPN # 2: (6) Nenhum agente estava disponível para este pedido.
Eu tentei criar manualmente um arquivo conf, que parecia ser parcialmente bem-sucedido. ifconfig tinha um item extra chamado tun0 , eu podia fazer ping de sites usando URLs, mas não conseguia carregar nenhum site no meu navegador. Isso pode ser uma indicação de que o meu problema é semelhante ao este , mas não é bem assim, porque não ter sites funcionando é uma restrição. Foi o que eu fiz lá:
user@hostname:~$ sudo vpnc-connect /etc/vpnc/my_vpn_config.conf
[sudo] password for user:
Enter IPSec secret for [email protected]:

kvpnc dá error: Timeout while connecting to 123.123.123.123. vpnc connect process will be killed. O ping do gateway retorna dentro de 50 ms.
Não tenho muita certeza do que mais tentar. Outras opções (pptp, openconnect, openvpn) parecem exigir um certificado de CA, o que eu não tenho, então eu suponho que estou preso com o vpnc. Espero que alguém tenha algumas ideias?
Editar: parece ser uma variante do este bug , embora a correção não tenha funcionado para mim.
