How to install the Citrix client on Ubuntu 22.04

The Citrix client provided by Citrix doesn’t currently work with Ubuntu 22.04. There is another way.

Why the normal deb install won’t work

If you’ve tried to install the Citrix Workspace deb package you’ll notice you get the error about libidn11 missing. It looks like Citrix haven’t updated their installer yet.

% sudo dpkg -i icaclient_22.3.0.24_amd64.deb 
[sudo] password for reepy:

Normally you’d install that missing package but libidn11 is not available on Ubuntu 22.04. It’s been replaced with libidn12 which isn’t compatible. You can install older versions, but there is an easier way.

Install the tar.gz instead

You’ll need to be familiar with the terminal and basic commands. You will not need root access to install this.

  1. From the Citrix Workspace download page in the ‘tarball package’ section download the latest x86_64 tar.gz.
  2. Open a terminal
  3. Get ready to install it:
    1. Go to the directory you downloaded it to: cd Downloads (or whatever directory you downloaded it to).
    2. Make a temporary directory: mkdir icaclient
    3. Go to that directory: cd icaclient
    4. Extract the tar.gz: tar -zxvf ../icaclient*.tar.gz
  4. Start the setup:
    1. Run the setup: ./setupwfc
    2. In the setup answer 1 to install, accept the default install location then no to GStreamer.
    3. Once it takes you back to the menu you can select 3 to quit.
  5. You now need to add some additional SSL certificates:
    1. cd ~/ICAClient/linuxx64/keystore/cacerts
    2. ln -s /usr/share/ca-certificates/mozilla/* .
    3. c_rehash .
  6. To solve ‘Error 61’ there are a few additional steps, thanks to Luk in the comments:
    1. cd ~/ICAClient/linuxx64/keystore/cacerts
    2. ln -s /etc/ssl/certs/* .
    3. ~/ICAClient/linuxx64/util/ctx_rehash

You should now be able to use the Citrix client from your web based Citrix portal.

    • I Tried that but go an error 61: you have not chosen to trust “DigiCert High Assurance EV Root CA”
      I just need to change the permissions on the certificate but I don’t no how to get to /opt/Citrix/ICAClient/Keystore/cacerts
      In ubuntu 20.04 you just put in terminal sudo nautilus and then go and find the cacerts folder, I don’t no how to do it in ubuntu 22.04 can you help?

  1. Thank you so much, I’ve been trying to solve this (and forced to use Citrix in Windows in VMWare) since I migrated over 3 years ago.

  2. Hello:
    I am admittedly an amateur. I have followed your directions and then when I try to open my citrix site Ubutnu asks what application I want to use to open the downloaded ica.


    • Try manually running the client program from where you installed it. You can also select the program by browsing to it. Worst case you can associate that file in Ubuntu with that app and manually open the download – I had to do that for a while.

  3. Hello!
    You solved a big problem for me: after switching to ubuntu 22.04, I suddenly found a dependency problem and this site is the only one with a solution, incredible luck was to find it!

    Спасибо ;)

    • Hey Ze,
      Could you please recommend other download location? So far I only can find the link which you say it did not working. I do not want to risk again. I have been reinstall Ubuntu twice so far.

      Thank ahead.


  4. Anyone can help? getting error not a directory:

    ~/ICAClient/linuxx64/keystore/cacerts$ ln -s /usr/share/ca-certificates/mozilla/*
    ln: target ‘/usr/share/ca-certificates/mozilla/XRamp_Global_CA_Root.crt’: Not a directory

    • You’re missing the final argument, which is the current directory ‘.

      ln -s /usr/share/ca-certificates/mozilla/*
      ln -s /usr/share/ca-certificates/mozilla/* .

  5. Thanks for the good tip. However, I have no problems at all with the installation through dpkg -i. It installs normally, but after receiving the certificat no further interface opens. In ICAClient.log it says the following:

    2022-07-13 14:40:05.647 [WEBHELPER] citrix-ctxwebhelper: parseArgs::error no keyword found

    Maybe someone can help with this

    • Same for me and the EPA plugin not starting. Only download button for nsepa appears in browser after a few seconds.

  6. icaclient_22.9.0.21_amd64.deb

    Worked for me on ubuntu 22.04 now without mucking around:

    % dpkg -i icaclient_22.9.0.21_amd64.deb

    It seems to depend on both/either libidn12 or libidn11

  7. Hi I followed all above instructions but still I get a ssl 61 error.

    laptop@laptop:~/ICAClient/linuxx64/keystore$ ls -lrt
    total 28
    drwxr-xr-x 2 laptop laptop 4096 nov 18 10:25 intcerts
    drwxr-xr-x 2 laptop laptop 20480 nov 18 10:26 cacerts

    I followed the instructions: ./setupwfc
    # cd ~/ICAClient/linuxx64/keystore/cacerts
    # ln -s /usr/share/ca-certificates/mozilla/* .
    # c_rehash .

    but still no luck for me..

    Someone an idea


  8. I’m a new user of Linux (Ubuntu) after 25 years of windows. I´’m very happy with my choise of migrateing from Windows.
    I tried serval suggestions (about 40 atempts) before i got CItrix to work.

    Downloaded the Citrix version:

    Open Terminal and wrote:

    ln -s /usr/share/ca-certificates/mozilla/*
    ln -s /usr/share/ca-certificates/mozilla/* .

    Did a reboot and then everything worked just fine!

  9. I did the installation in late December and got this version from the Citrix website:


    After the five installation steps mentioned above I got stuck with the “you don’t trust… error 61” message. After some research I tried to link to the certificates in /etc/ssl… instead of /usr/…mozilla

    cd ~/ICAClient/linuxx64/keystore/cacerts
    ln -s /etc/ssl/certs/* .

    It worked for me after this. No reboot or root operations needed. Maybe someone knowledge can explain this to the world.

    • Thanks for figuring this out! I’ve updated the original post.

      It works because you’re making more SSL certificates available to Citrix, even though it should really look there without this step.

  10. Made an install on Mint 21.1 on Tuesday and it worked without problems on my Lenovo Yoga910.
    Tried to do it on my ideapad320 with Mint 21.1 alternate work notebook with better support for external displays), but got the libidn11 error on this one, although I updated it from 21.0 before especially for Citrix.

    Tried the fix above (thanks!), but on this machine opening the same .ica files with FF now try to use the without any further reaction. Does someone have an idea?
