Unfortunately, there is no 64 Bit package for the Citrix client 11. So, it is a smaller challange to install the client using 32 bit libraries. There are a couple of nice tutorials on the net. The one which helped me most was the how to by I can has linux. Basically it describes, that one should download the current 32 Bit Linux client from the Citrix Download Page. After running the basic installation you’ll need to download the Motif 32Bit Libraries, extract its files using ar and copy its libs to /usr/lib32 on your Ubuntu system.
But I still had a few issues installing the client: A symbolic link called libXm.so.4 was missing in the first place. To fix that, I did the following:
cd /usr/lib32 sudo ln -s libXm.so.3.0.2 libXm.so.4
Now, I was able to start the client: /usr/lib/ICAClient/wfcmgr
Trouble connecting via SSL
But when I tried to connect to a SSL Host, the connection broke telling me that To fix this, 2 steps are required. Download the certification files. Now, move the files to /usr/lib/ICAClient/keystore/cacerts or whatever the installation directory of your client installation is.
After that, Citrix client and connecting SSL hosts worked like a charm.
