Perhaps this gives some more insight: https://docs.citrix.com/en-us/citrix-workspace-app-for-linux/whats-new.html https://docs.citrix.com/en-us/citrix-workspace-app-for-linux/citrix-workspace-app-for-linux.pdf More precise requirements are mentioned, quotes from these docs: "In earlier releases, the self-service UI required libwebkitgtk Version 1.0. Since, the webkitgtk version 1.0 is deprecated, most Linux distributions have deprecated support. Going forward, Citrix Workspace App for Linux is dependent on libwebkit2gtk (2.16.6+)." And perhaps for this bugreport: "ICA launch might fail on Fedora 29/30. As a workaround, follow the steps: Install openssl10 by using the command sudo yum install compat-openssl10.x86_64 Set the environment variable in ~/.bashrc to load for every session. This action points to the older libcrypto library. export LD_PRELOAD=/lib64/libcrypto.so.1.0.2o"
