Minha conexão VPN não está funcionando para mim em uma instalação limpa do Kubuntu 15.04, e estava em 14.10 e versões anteriores. Posso configurar uma conexão através do "editor de conexão", mas quando quero conectar, aparece uma janela que provavelmente é onde devo digitar as senhas (mas desaparece imediatamente, então não sei dizer). Depois de dizer por um tempo que está se conectando, ele desiste. O syslog se parece com isto:
grep NetworkManager /var/log/syslog

Criar uma conexão com as senhas na configuração também não ajudou: 9 de julho 16:46:17 hostname NetworkManager[811]: [1436453177.020663] [vpn-manager/nm-vpn-connection.c:1778] get_secrets_cb(): Falha ao solicitar segredos VPN nº 2: (6) Nenhum agente estava disponível para esta solicitação.
Tentei criar manualmente um arquivo conf, que pareceu ter sido parcialmente bem-sucedido. ifconfigtinha um item extra chamado tun0, eu conseguia executar ping em sites usando URLs, mas não conseguia carregar nenhum site no meu navegador. Isso pode ser uma indicação de que meu problema é semelhante aoEste, mas não é bem assim, porque não ter sites funcionando é uma restrição e tanto. Isto é 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]:

o syslog para esta conexão é assim:

kvpncdá error: Timeout while connecting to 123.123.123.123. vpnc connect process will be killed.Pinging ao gateway retorna dentro de 50ms.
Não tenho muita certeza do que mais tentar. Outras opções (pptp, openconnect, openvpn) parecem exigir um certificado CA, que eu não tenho, então presumo que estou preso ao vpnc. Espero que alguém aí tenha algumas idéias?
Editar:parece ser uma variante deesse bug, embora a correção não tenha funcionado para mim.
