Ubuntu 10.10 and Citrix

Many of us with the opportunity to work from home will have met up with logging via a Citrix server. With that in mind, I set to getting an ICA client going on my main Ubuntu box at home. There is information scattered about the web in the form of a question on the Ubuntu forum and a step-by-step guide by Liberian Geek. To summarise the process that I followed here, you have to download a copy of the Citrix Receiver installer for Linux from the company's website. There, you'll see DEB and RPM packages, along with a tarball for other systems. The latter needs a bit more work, so I got the x86 DEB package and installed that in the usual way, using Ubuntu's Software Centre to do the installation following the download. Needing to start the Citrix connection via a browser session meant that a browser restart was needed too. That wasn't the end of the leg work because Thawte certificate errors were to stop me in my tracks until I downloaded their root certificates from their website. Once the zip file was on my PC, I extracted it and copied the required certificate (Thawte Server CA.cer from the thawte Server CA directory) to /usr/lib/ICAClient/keystore/cacerts on my system; it helped that the error message had told me which was the one I needed from the collection in the zip file. With that matter addressed, the connection happened without a glitch, and I was able to get to working without recourse to a Windows virtual machine. For once, Linux wasn't to be excluded from one of the ways of using computers that has been getting more prevalent these days.

Update 2012-04-14: On an equivalent installation on Linux Mint Debian Edition, I found that the installation location for the certificate had moved to /opt/Citrix/ICAClient/keystore/cacerts. This was for the 64-bit edition.

Update 2012-12-17: The above applied to an installation of version 12.10 on 32-bit Ubuntu GNOME Remix too.
