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? –  Thomas W. Jun 22 '12 at 16:48
    
yes, it is really 32bit ediation software. –  chuck Jun 22 '12 at 17:02
    
i used ubuntu-12.04-desktop-amd64.iso installed.

i make a problem, i rebuilt lib32-libxml2, and relink tha share lib. Then i found is can be install successfully. but it still can work normally. that was strage, From the dmesg, i found vpn module already load. –  chuck Jun 22 '12 at 17:31
    
i try to manually run vpnui, found some errors.chuck@chuck:/opt/cisco/vpn/bin$ ls manifesttool vpn vpnagentd vpndownloader vpndownloader.sh vpnui vpn_uninstall.sh chuck@chuck:/opt/cisco/vpn/bin$ ./vpnui ./vpnui: error while loading shared libraries: libatk-1.0.so.0: cannot open shared object file: No such file or directory so i build lib32-atk for that. –  chuck Jun 22 '12 at 17:40

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-gnome

I use this too in place of the cisco software, but it's really just a workaround. My University is doing an update of cisco this week and I'm a little antsy it will break the compatability –  Ian B. Aug 8 '12 at 12:32
    
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. –  Jan Vlcinsky Jun 11 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. –  Mike Jul 22 at 19:50

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.

Never mind, I installed OpenConnect with the instructions here: http://faq.oit.gatech.edu/content/cisco-anyconnect-installation-instructions-linux

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. –  Hypercube Jan 31 '12 at 0:12
    
The link is broken now unfortunately. –  pthurmond Mar 25 at 18:35
sudo apt-­get install network­-manager­-pptp 
sudo apt­-get install network­-manager­-vpnc
sudo apt-­get install network­-manager­-openvpn 
exit
  1. If prompted for your password, type it, and press Enter.
  2. If you're told that a package “is already the newest version,” ignore it and continue with the next command.
  3. If asked to “continue [Y/n],” press Y, followed by Enter. then : enter image description here

After STEP 3 :

This worked for me on Ubuntu 14.04 64-bits. Just the network­-manager­-vpnc. And the connection seems stable so far. –  Jan Vlcinsky Jun 11 at 22:13
