VMware Horizon Client not working in Ubuntu 20.04 LTS
For me, installing intel-media-driver-non-free was the solution (at least on ubuntu 20.10). Disabling h.264 in the VMware Blast options also worked, but resulted in terrible image quality.
The Ubuntu 20.04 contains libffi.so.7. The missing libffi.so.6 fails launching the vmware client.
I made a symlink to solve this issue:
/usr/lib/x86_64-linux-gnu $ ln -s libffi.so.7 libffi.so.6
