Recent Update broke Cisco-VPN connection

[pheidrias]

After a recent upgrade (2013-04-10), which included network-manager-vpnc_0.9.6.0-0ubuntu2, my system fails to connect to Cisco VPN I'm not able to connect to my Cisco VPN Network. I get the the Error "Aktivierung der Netzwerkverbindung ist gescheitert" and tail -f /var/log/syslog yields:

I'm on Raring Ringtail 13.04, 64Bit, Gnome-Shell 3.8 with all updates.

I'm not sure, which packages are responsible for the error. It worked fine before. I can not connect manually via vpnc, which however hasn't worked before, neither.

I am on Ubuntu 13.04 64-bit with all the updates as of May 28th.

[Diethard Steiner (diethard-steiner)]

Same problem here.

[Gujs (gregor-fuis)]

I have the same problem also. All latest updates installed.

[John Pang (john-pijin)]

I'm getting this problem on Ubuntu 13.04 64-bit with all the updates as of 2nd Sept.

[Nathan Gaida (nfgaida)]

Getting the same problem, Ubuntu 13.04 32bit, all updates as of 16th Sept. I have verified my VPN credentials are valid on another machine (OSX), and I was able to connect from the Ubuntu machine a few days ago.

[Nathan Gaida (nfgaida)]

To follow on my issue: I was near my password expiration date (I had 2 days left). When I connected with OSX it asked me if i wanted to change my password (the VPN client did). So when I was at work, I changed my password. Now, I have no problem logging in with my Ubuntu machine. I suspect that the linux VPN client isn't able to handle the "do you want to change your password" message from the server and disconnects.

[Roland Roberts (1oland)]

This started with some update on 13.04 64-bit in the past week. My password was no where near expiration, so that's not the issue.

[Roland Roberts (1oland)]

In my case, I finally tracked it down to having somehow clicked on "use hybrid authentication". That and the group password disappeared.

Just upgraded to 14.04 and ran into this issue.
