Citrix ICA Client (Xenapp) on Ubuntu
Since I am building a machine from scratch right now, a number of things are becoming minor annoyances. Thankfully the interwebs are alway standing by to provide answers. Since I managed to find answers to this particular issue, in a myriad of different places (all linked to at the bottom of this post), I figured I might as well bring them all into one location. Also, please note, these instructions are usually compiled for folks who know nothing about Ubuntu or libraries, or security certificates etc.. If you are indeed knowledgeable about these things, feel free to skip this entire post.
The best guide for installing the Citrix XenApp Client is on Ubuntu’s forums.
Only follow instructions till the point where it gets to “Download Citrix client 10.6″… those are older instructions and you don’t need to follow them.
After that you will need the security certificates. Otherwise you will get the “you have chosen not to trust” error message when you connect to your Citrix server.
So to avoid doing that grab the certificates from the following locations :
i) Thawte Certs from :
http://www2.slac.stanford.edu/computing/windows/services/citrix/linux_client.htm
Grab both files – thawte-server-ca.crt and ThawteRoot.crt
ii) GoDaddy from :
https://certs.godaddy.com/anonymous/repository.seam
Grab the file gd-class2-root.crt
Download these, then move them into usr/lib/ICAclient/keystore/cacerts
Done. Once that happens, you should be able to open the ica files that Firefox gives you with the wcfmgr in /usr/lib/ICAClient folder.
You might need other certificates – download them and place them in the same directory. You can export certs from Opera if needed (I haven’t found how to do them from FF).
