Estou tentando fazer com que minha conexão openvpn funcione. Eu uso uma chave estática deste tutorial: link
Quando me conecto via terminal sudo openvpn --config client.conf está funcionando e recebo o ip da vpn.
Mas quando tento conectar via NetworkManager, recebo erros.
Meu sys.log da Mint (Sylvia):
