Fixing Server Certificate Problem with Cisco AnyConnect VPN Client

12.04ciscovpn

When I try to connect using the Cisco AnyConnect VPN Client, I receive this error:

Connection attempt has failed due to server certificate problem.

Connection attempt has failed due to server certificate problem.

I happened to have this problem in my previous Ubuntu 11.10 installation. That time I could fix it using some tutorials on the internet (I don't remember which one). Basically, they suggested installing 4-5 packages and then some ln -s. But this time none of them are working. Can anyone help me step by step?

I can confirm that this problem exists. Anyconnect client worked fine with 11.10 but stops working with 12.04. Old trick with links to firefox libraries does not work anymore. I end up using OpenConnect.
