Just in case you do want the Ciso Anyconnect client working take a look at this blog. Just disable the Firefox Iced Tea web plugin and go to your VPN site. Have Ubuntu download the VPN installer and run the shell script. In my case Cisco Anyconnect VPN client was installed and available under the Internet section and works fine. Use the GUI App to install the Cisco AnyConnect Diagnostic and Reporting Tool. If the GUI installation doesn’t work, run the commands below to install it. That should install AnyConnect for you including DART After that, Cisco AnyConnect Secure Mobility Client should be ready to use. Introduction This document describes a configuration example for Adaptive Security Appliance (ASA) Cisco AnyConnect Secure Mobility Client access that uses client certificate for authentication for a Linux Operative System (OS) for an AnyConnect user to connect successfully to an ASA Headend. Contributed by Dinesh Moudgil, Cisco HTTS Engineer.

As part of its ongoing cybersecurity strategy, The Division of Information Technology has implemented a mandatory two-factor authentication for the Enterprise Virtual Private Network (VPN)

To increase security measures on your account, two-factor authentication requires two steps to log in. The first step is using something you know (i.e., your password), and the second step is something you have (i.e., cell phone) to securely verify your identity.

• Enroll your phone for two-factor

Please review these simple step-by-step instructions below to enroll your phone:

• Visit login.fiu.edu/enroll
• Log in using your FIU username and password
• When prompted, enter the phone number of the device you would like to enroll in two-factor authentication (FIU numbers will not be accepted).
• Specify what type of device corresponds to the enrolled number
• When prompted, enter the code you received
• You are now enrolled in two-factor authentication

TwoFactor with VPN

Launch your Cisco AnyConnect VPN client, you will be prompted for your FIU username, password, and a “second password”. In this second password field, you will specify your preferred verification method (“something you have”).

In the second password field, you will be required to type “push”, “phone”, or “sms”.

• Push: uses the DUO Mobile app *
• Phone: places an automated voice call *
• SMS: sends unique verification codes via text messages **

(*Note: Your carrier’s data and message rates may apply)

(**Note: Your carrier’s data and message rates may apply, 10 codes are sent in one text message to use 10 different times.)

Notes:

Cisco Anyconnect Secure Mobility Client Ubuntu 18

• Once the Anyconnect is installed on your machine, it will always be automatically upgraded to the latest version as they are published by Network Services. You shouldn't need to go through the manual installation process unless you reinstall your operating system, or your client becomes corrupted and needs to be uninstalled and reinstalled.
• After connecting for the first time, the VPN policy will be pushed to your client. The pulldown will say 'Gatorlink VPN' rather than vpn.ufl.edu after this policy is downloaded.
