Install Citrix Receiver on Ubuntu 12.04

Update 2014-01-03: Installing Citrix in Linux is still a hazzle. Please have a look at my new post: Install Citrix Reciever 13 on Ubuntu 13.10. The below post applies to the older Citrix Client version 12.

Installing Citrix in Linux is always a hazzle. The following worked for me on a fresh installation of Ubuntu 12.04.

Prerequisites (amd64):

$ sudo apt-get install ia32-libs-multiarch:i386
$ sudo apt-get install libmotif4:i386

Prerequisites (i386):

$ sudo apt-get install libmotif4

Now choosing Citrix version was not so easy… I found:

icaclient_12.0.0_amd64.deb     (failed to meet dependencies)
icaclient_12.1.0_amd64.deb     (failed to meet dependencies)
icaclient_12.0.0_i386.deb      (OK! - both i386 & amd64)
icaclient_12.1.0_i386.deb      (broken gzip!!!)
linuxx86-  (did not test)
linuxx86-  (broken gzip!!!)

The amd64 bit packages do not seem to contain a 64-bit Citrix client. They are just built to install cleanly on a 64-bit system, but it doesn’t on Ubuntu 12.04 (perhaps better luck in Debian). The broken gzip-errors were really weird.

amd64 specific plugin issues
Now when Citrix is installed it can be useful to know that it ends up in /opt/Citrix. That is, on amd64, you need to tell Firefox to open ica-files with /opt/Citrix/ICAClient/wfica. The plugin /opt/Citrix/ICAClient/ appears to be i386 (no suprise) and will not work with amd64. I tried to install firefox:i386 instead of the amd64-version, but then none of the other plugins worked. It is probably possible to fix, but I will not.

Also, you (may) need to fix certificates:

zo0ok@oden:/opt/Citrix/ICAClient/keystore$ ls
zo0ok@oden:/opt/Citrix/ICAClient/keystore$ sudo mv cacerts cacerts.orig
zo0ok@oden:/opt/Citrix/ICAClient/keystore$ sudo ln -s /usr/share/ca-certificates/mozilla cacerts

Finally, Citrix receiver 12.0 works nicely in Unity and Ubuntu 12.04. This was not the case a few versions ago.

  1. Hello zoo0ok,

    your solution works perfectly for me.

    Thank you for sharing.

  2. worked for me with icaclient_12.1.0_i386.deb. though i got an error the citrix receiver is still working ..

    Selecting previously unselected package icaclient:i386.
    (Reading database … 299879 files and directories currently installed.)
    Unpacking icaclient:i386 (from icaclient-12.1.0_i386.deb) …
    Setting up icaclient:i386 (12.1.0) …
    dpkg: error processing icaclient:i386 (–install):
    subprocess installed post-installation script returned error exit status 2
    Processing triggers for menu …
    Errors were encountered while processing:

  3. I get the same error message as fren but haven’t the foggiest idea how to resolve it.

  4. Same here.
    I have just a few moments to install it …
    Damnit !

  5. I found this link to work around the dpkg error, which worked for me using the 12.1 64-bit package.

  6. I tried Garys link and it seems to work. I was using the x86 (not x64) version of Citrix (on 64-bit Ubuntu), but the annoying error disappears when in the file /var/lib/dpkg/info/icaclient.postinst
    I replaced
    echo $Arch|grep "i0-986" >/dev/null
    echo $Arch|grep -E "i0-986|x86_64" >/dev/null

    As I understand it this just makes the postinst-script exit without error, but the error was not real (or at least severe) in the first place. You can confirm that things work properly by running this command
    $ sudo dpkg --configure icaclient:i386
    and you should no longer receive errors.

  7. Hey Thanks ..worked for me 🙂

  8. I have followed your instruction and I am struggling to open the icaclient through firefox. I got:
    “Cannot connect to ‘…’. Operation not permitted. Verify your connection setting and try again.”
    Any idea? Thanks!

    Works perfectly.
    I chose icaclient_12.0.0_i386.deb because you said it should work.
    I had to do a litte homework on how to get that package, and then how to install in (yes: newbie):
    And I needed to do the certificate trick.
    Thanks a lot for sharing!
