I installed Cisco AnyConnect for Ubuntu(64) 12.04, but it failed. It can be installed on Ubuntu 10.10(64).

The error log

Installing Cisco AnyConnect VPN Client ...
Extracting installation files to /tmp/vpn.teuSIr/vpninst096243274.tgz...
Unarchiving installation files to /tmp/vpn.teuSIr...
Starting the VPN agent...
/opt/cisco/vpn/bin/vpnagentd: error while loading shared libraries: libxml2.so.2: cannot open shared object file: No such file or directory

When I meet that,

locate libxml2.so.2
/usr/lib/x86_64-linux-gnu/libxml2.so.2
/usr/lib/x86_64-linux-gnu/libxml2.so.2.7.8

So I create symbol link libxml2.so.2 in /user/lib and after I do:

Installing Cisco AnyConnect VPN Client ...
Extracting installation files to /tmp/vpn.5cz4FV/vpninst001442979.tgz...
Unarchiving installation files to /tmp/vpn.5cz4FV...
Starting the VPN agent...
/opt/cisco/vpn/bin/vpnagentd: error while loading shared libraries: libxml2.so.2: wrong ELF class: ELFCLASS64

I ensure that there exist lib32 runtime lib on my device.

How can I fix this?

  • That ELFCLASS64 seems to suggest you're using a 64bit software on a 32bit OS. Did yuo make sure you're using the 32bit edition of the software?

If you don't need the "official" Cisco AnyConnect VPN software, I highly recommend installing the "network-manager-openconnect-gnome" package in the Ubuntu Repository. It uses OpenConnect which is an open source client for AnyConnect.

Anyhow, that package allows for you to configure and manager your AnyConnect VPN connections through the normal network manager.

I have been using that to connect to my work VPN for the past few months and it has been working great!

You can find the package in the Ubuntu Software Center or Synaptic by searching for "OpenConnect." If you wish to install it via the command-line, you can do so with:

sudo apt-get install network-manager-openconnect openconnect

For the GUI you can additionally install the *-gnome package using:

sudo apt-get install network-manager-openconnect-gnome

This adds an option to Network Connections. When you choose to add a connection, there'll be a new option under VPN Connections to add a "Cisco AnyConnect Compatible VPN (openconnect)". You can then connect to the VPN through the networks applet (in the system tray).

    This solution did not work for me on 64-bit Ubuntu 14.04. It did not offer the UI needed to connect, I missed e.g. an option to enter group and user name and password. Jun 11, 2014 at 22:11

    I like this answer (as it worked for me), but feel it's missing half of the explanation. This adds (at least on Linux Mint) an option to Network Connections. When you choose to add a connection, there'll be a new option to add a "Cisco AnyConnect Compatible VPN (openconnect)". You can then connect to the VPN through the networks applet (in the system tray). This seems the ideal place for it.

    Still works like a charm. Only needed to insert the gateway in NWM and the rest was just point and click the cert, username and password.

    Downloading "official" Cisco AnyConnect VPN software is not available for every body. "network-manager-openconnect-gnome" works fantastic. :) Apr 21, 2016 at 9:37

Use openconnect! quite easy!

  1. First run command below to active th TUN module:

    sudo /sbin/modprobe tun
    
  2. Install OpenConnect:

    sudo apt-get install openconnect
    
  3. Connect to VPN, run:

    sudo openconnect yourvpn.example.com

  1. Install some VPN plug-ins for Network Manager:

    sudo apt-­get install network-manager-pptp network-manager-vpnc network-manager-openvpn network-manager-openconnect-gnome
    
  2. If prompted for your password, type it, and press Enter.

  3. If you're told that a package “is already the newest version,” ignore it and continue with the next command.

  4. If asked to “continue [Y/n],” press Y, followed by Enter.

  5. Open the connections settings dialogue, go to the VPN tab and add a new connection:

  6. Select “Cisco AnyConnect”:

    This worked for me on Ubuntu 14.04 64-bits. Just the network­-manager­-vpnc. And the connection seems stable so far. Jun 11, 2014 at 22:13
  • I tried this under Ubuntu 14.04 64-bit. The VPN compatible Cisco Anyconnect (openconnect) option is not available. It states the ...may not have correct VPN plug-in installed. Aug 6, 2015 at 8:21

    Need to install sudo apt-get install network-manager-openconnect-gnome which contains the required plug-ins. Aug 6, 2015 at 8:30
  • Stupid question but I don't have the Icons on the top right on the bar (amongs which is the network connections one) any way to turn those on. Or a another way to get to the same options.

  • This doesn't work for me because one of the required configurations is "group name" and "group password". I have no idea what those should be and neither the official client or openconnect require them.

I encountered a similar issue earlier. I observed that vpnagentd does not load because of libatk1 and vpnui does not load because of libxml2. Installing the 32-bit versions of these libraries resolves the issues. You should install ia32-libs to resolve the issue using

sudo apt-get update
sudo apt-get install ia32-libs

This should resolve the issue for you on Ubuntu 64 bit versions. I have tried it on Ubuntu 11.10 and Ubuntu 12.04.

I just installed openconnect. Works similarly to the anyconnect command line utility.

sudo apt-get install openconnect

As of Ubuntu 18.04, OpenConnect VPN client is available as an add-on to GNOME Control Center, as shown here:

enter image description here

To enable this add-on, you can search for 'openconnect' in ubuntu software center like so:

enter image description here

Then click on gnome control center and check the checkbox for 'OpenConnect VPN Client'.

Never mind, I installed OpenConnect with the instructions here. Finally, I don't have to deal with that Cisco garbage!

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.

  • Thanks! I think I'll stick with OpenConnect though.

In my casevpnagentd would not load. Installing the packages

sudo apt-get install lib32z1 lib32ncurses5

however, resolved the problem for me. The terminal promted the message to install these, when I tried to install ia32-libs, which seems to be obsolete.

Here are procedure that worked for me on Ubuntu 64 bit desktop 14.04.3

sudo apt-get install -y lib32z1 lib32ncurses5 lib32bz2-1.0 libxml2:i386 libstdc++6:i386 libgtk2.0-0:i386 libpango1.0-0:i386

Now, I can ./vpnui to launch.
