Installing AnyConnect Secure Mobility Client v4.9.x
Step 1
Download the AnyConnect Pre-Deployment Package for Linux from Cisco Software Downloads.
The latest release at the time of publication was 4.9.01095.

Open the Terminal by pressing Ctrl+Alt+T on your keyboard. To navigate to the folder where you have downloaded the AnyConnect Client Package, use the command, ‘cddirectory name’. For more information on the ‘cd’ command, click here.

The filename will auto-populate. If it doesn't even after you press tab twice, it indicates that you need to type more number of unique characters. Alternately, you can use the 'ls' command to list the files in your current directory.
Step 3
The initial download is a tarball archive (several files packed into one), which must be extracted. The command ‘tar xvffilename’ will extract the contents to the same directory in which the initial file is located.
For more information on the ‘tar’ command, click here.
Step 4
Once the folder is extracted, use the ‘cddirectory name’ command again to navigate into the folder.
