Install following:
sudo apt-get install ia32-libs-multiarch:i386
sudo apt-get install libmotif4:i386
Download 32-bit libmotif3 then execute the following:
dpkg -x libmotif3_2.2.3-4_i386.deb ./tmp
cd ./tmp
cd usr/lib
sudo cp libXm.so.3 /usr/lib32/
cd /usr/lib32
sudo ln -s libXm.so.3 libXm.so.4
Now download the ICA client from http://citrix.com (I used the tar.gz as the deb files are broken). The ICA client is in 32-bit no matter what version you choose so don't bother go for any 64-bit "version".
When the client is installed you need to give more CA certificates to trust:
root@host:/opt/Citrix/ICAClient/keystore$ ls
cacerts
root@host:/opt/Citrix/ICAClient/keystore$ sudo mv cacerts cacerts.orig
root@host:/opt/Citrix/ICAClient/keystore$ sudo ln -s /usr/share/ca-certificates/mozilla cacerts
