I have the same problem under Ubuntu 15.04 x64 for both PPTP and VPNC (Cisco IPsec old vpn client) connections. Openvpn connections seems not to be affected, but I did not test openvpn a lot.
I can find the same error on syslog: [vpn-manager/nm-vpn-connection.c:1778] get_secrets_cb(): Failed to request VPN secrets #2: (6) No agents were available for this request. It only happens at the first logon. If I logoff and then logon again, both PPTP and VPNC works fine. I'm using logoff+logon as a workaround, but it's very annoying. I did some debugging stopping and launching manually network manager with sudo NetworkManager -d --log-level DEBUG The most useful thing I noticed comparing the debug output of a working logon session with a non working session, is the presence of the following line only on the working session NetworkManager[5543]: <debug> [1440322623.554175] [settings/nm-agent- manager.c:330] impl_agent_manager_register_with_capabilities(): (:1.182/org.freedesktop.nm-applet/1000) requesting permissions The above line does not appear when I'm inside a "first logon" (not working) session. It seems that nm-applet is unable to register as an agent to NetworkManager, but only at the first login. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager-pptp in Ubuntu. https://bugs.launchpad.net/bugs/1483431 Title: PPTP VPN fails with 'Failed to request VPN secrets' Status in network-manager-pptp package in Ubuntu: Confirmed Bug description: I've been being running Ubuntu 15.04 without problems until a recent system update.
