But if you are unsure, just run the uname command like this: $ uname -a

If you are usure whether you should use the 32 or 64 bit client: Most people are on 64-bit machines now.

Download the 32 or 64 bit client as a.

Go to the UCI OIT Cisco Anyconnect/Linux instruction page.

$ sudo apt-get install lib32z1 lib32ncurses5

First, make sure you have the necessary Debian/Ubuntu support packages installed: $ sudo apt-get update.

If you get it going for yourself, though, Kudos to You! :-) Installing the Cisco An圜onnect client I no longer do this, as it is too complicated these days to keep up with documenting the various desktop environments, and the changes (and unreliability) of NetworkManager. I used to also include instructions for getting VPN support to show up in the NetworkManager icon/applet in the system tray, for those who used a Gnome based desktop.

When you're done, you'll have two commands available at the command-prompt, which you can run to connect to the campus VPN: 'vpn' (text mode) and 'vpnui' (graphical/windowing). In the instructions below, I'll walk you through installing the Cisco VPN client on a Debian or Ubuntu system.

Thanks to several for the help getting here. I'd love to hear that it helped someone and/or any improvements that could be added. Please do write me to let me know how it went for you, and/or with any suggestions. It should work for most or all Debian-derived distributions through 9.0 ('Stretch'). I originally wrote this 'How-To' for Ubuntu v10, and have updated it through v17.04. OIT has a good general VPN-Linux page with instructions on setting up the Cisco An圜onnect 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. (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.)
