(Note: There is also an alternative method of installing UCI VPN support without using the Cisco client, but using the built-in Debian/Ubuntu openconnect and openvpn drivers, should you find the below method does not work for you, or if you prefer to use open-source non-proprietary software.)
OIT has a good general VPN-Linux page with instructions on setting up the Cisco AnyConnect VPN client software for Linux, but I got tripped up in a couple of places and thought I'd pass on some heads-ups for other Debian and Ubuntu users.
I originally wrote this "How-To" for Ubuntu v10, and have updated it through v15.04. It should also work (or at least get you in the ballpark) for any Debian-derived distributions.
Please do write me to let me know how it went for you, and/or with any suggestions. I'd love to hear that it helped someone and/or any improvements that could be added.
Thanks to several for the help getting here.
To get the Cisco VPN client working for an Ubuntu system, you'll need to install at least the Cisco AnyConnect client (Section 1). This gives you the core VPN functionality -- a shell vpn command to connect to / disconnect from the UCI VPN. KDE users (like myself) will have to use this method and stop here.
If you run a Gnome-based desktop, you can also optionally add the Linux NetworkManager OpenConnect GUI icon to connect and disconnect from the UCI VPN using your mouse. (Section 2)

VPN> connect vpn.uci.edu >> Please enter your UCInetID and password. 0) Default-WebVPN 1) Merage 2) MerageFull 3) UCI 4) UCIFullIf you do not see this, but get a connect error instead, please see NOTE 1 - Connect Error below.
In most cases I have seen, a connection is made. I have, however, seen the below error before only once. It was when the person was installing on a netbook (running Gnome) which was on campus and usingthe campus wifi system (though I don't know if those factors were the cause). It didn't matter if they answered y or n, they continued to get the error and be denied connection.
If you get this error, call OIT Help desk at 949-824-2222, or write them at email@example.com. If you find a solution, I'd appreciate knowing what it is: (jas at uci dot edu). Thx.

Having installed the core VPN functionality (in Section 1 above), you can actually stop there if you prefer, and from now on, just connect and disconnect using your terminal per the above instructions. If, however, you're using a Gnome-based desktop environment, you also have the option of connecting and disconnecting to the VPN via the NetworkManager icon. Instructions for adding that functionality are below. (If you do install the NetworkManager icon functionality, you can still use the command-line method, too.)
in a terminal, type:
sudo apt-get install network-manager-openconnect(or install via Synaptic)
(From now on, all you should have to do is this section any time you want to connect.)
now all your connections to UCI (web, ssh, ftp, etc.) will be through the VPN until you disconnect.
Please email me to let me know how this process went for you, and/or with any suggestions for improvement on this page itself. Thanks.
(1) or from the main desktop menu, click System->Preferences->Network Connections and select the VPN tab. OR from the main desktop menu, click Settings Manager->Hardware->Network Connections. One of these (or something like them) should get you in the ballpark. (Don't you just love the Linux desktop zoo???)
