Or: How I Learned to Stop Worrying and Love Symlinks

So you did the responsible thing: updated to Ubuntu 24.04, grabbed the latest Citrix Workspace .deb, and… nothing. No window, no error, just radio silence from wfica.

It’s not you. It’s not even (entirely) Citrix. It’s the GTK WebView system in Ubuntu moving on, and Citrix Workspace not updating its address book.

But fear not — we can coax it into working with a few good ol’ symbolic links. Here’s how to fix the “Citrix doesn’t start at all” bug on Ubuntu 24.04.

The Real Problem: GTK WebView Dependencies

he Citrix Workspace GUI depends on GTK-based WebKit components — specifically:

• libwebkit2gtk-4.0.so.37
• libjavascriptcoregtk-4.0.so.18

But in Ubuntu 24.04, those versions are gone. Instead, we now have:

• libwebkit2gtk-4.1.so.0
• libjavascriptcoregtk-4.1.so.0

Citrix Workspace is too picky to use the newer ones unless you trick it. So… we trick it.

The Actual Fix: Symlinks for GTK WebView Libraries

Step 1: Install Dependencies

cd /opt/Citrix/ICAClient/gtk2/lib

sudo ln -s /usr/lib/x86_64-linux-gnu/libwebkit2gtk-4.1.so.0 libwebkit2gtk-4.0.so.37
sudo ln -s /usr/lib/x86_64-linux-gnu/libjavascriptcoregtk-4.1.so.0 libjavascriptcoregtk-4.0.so.18

Why this works: Citrix is hardcoded to look for the old file names. By symlinking the new libraries to the old names, we give it exactly what it wants — without needing to downgrade anything.

If you do not want to trick it by linking in the 4.1 versions, search your /snap/gnome/ hierarchy, and you will likely find the files there in the required version.

I have seen that other lib files might be required as well, like libicui18n.so.70, libicuuc.so.70, and libicudata.so.70.

if that is the case (and you can verify that by checking your /var/log/syslog when starting Citrix), then just symlink the hell out of them.

sudo ln -s /usr/lib/x86_64-linux-gnu/libicui18n.so libicui18n.so.70
sudo ln -s /usr/lib/x86_64-linux-gnu/libicuuc.so libicuuc.so.70
sudo ln -s /usr/lib/x86_64-linux-gnu/libicudata.so libicudata.so.70

Bonus Fixes for a Smooth Citrix Experience

Associate .ica Files

 xdg-mime default wfica.desktop application/x-ica

ICA Files Not Launching from Browser?

Your browser may just download .ica files and ignore them. You can either:

• Set Firefox/Chrome to always open .ica files with wfica
• Or launch them manually: /opt/Citrix/ICAClient/wfica ~/Downloads/launch.ica

USB & Audio Redirection

sudo apt install libusb-1.0-0

Also, install the Citrix USB deb.

sudo dpkg -i ctxusb_25.03.0.66_amd64.deb #whatever version you downloaded with your other deb

Then, launch Citrix Preferences using wfcmgr or selfservice and enable device redirection under Tools > Preferences.

Fix Certificate Errors

sudo cp /etc/ssl/certs/ca-certificates.crt /opt/Citrix/ICAClient/keystore/cacerts/
sudo update-ca-certificates

Full Cleanup (If everything else fails and you hate citrix)

sudo apt purge icaclient
rm -rf ~/.ICAClient ~/.Citrix

You can now start over and reinstall the ctrix deb again if you want to start over

TL;DR Cheat Sheet

sudo apt install libwebkit2gtk-4.1-0
cd /opt/Citrix/ICAClient/gtk2/lib
sudo ln -s /usr/lib/x86_64-linux-gnu/libwebkit2gtk-4.1.so.0 libwebkit2gtk-4.0.so.37
sudo ln -s /usr/lib/x86_64-linux-gnu/libjavascriptcoregtk-4.1.so.0 libjavascriptcoregtk-4.0.so.18
sudo ln -s /usr/lib/x86_64-linux-gnu/libicui18n.so libicui18n.so.70
sudo ln -s /usr/lib/x86_64-linux-gnu/libicuuc.so libicuuc.so.70
sudo ln -s /usr/lib/x86_64-linux-gnu/libicudata.so libicudata.so.70
xdg-mime default wfica.desktop application/x-ica

Aaaand we got liftoff

After all that, Citrix Workspace should stop ghosting you and finally launch like it’s supposed to. No more blank stares. No more frantic Googling mid-meeting. Just a remote desktop that works.

Ubuntu 24.04 is modern and slick. Citrix just needs a gentle nudge to come along for the ride.

Got a better workaround, or hit another edge case? Drop a comment — let’s fix this together, one symlink at a time….and yes, this should work on other Ubuntu-based distributions as well as the 25.xx generation of Ubuntu.
