I installed Matlab 2025a on Fedora 42 (which is not in the official list of supported OSes but still, RHEL is) but when opening Matlab and logging in, it crashes with the error:
Unable to communicate with required MathWorks services (error 5201).
For help with this issue, contact support:

Unable to launch MVM server: License Error: Licensing shutdown
Matlab support cut me off with "Fedora isn't supported", so we are not helping.
Are there any solutions? How do I lauch the MVM server?
Thanks

The solution turned out to be run manually
InstallMathWorksServiceHost
as the local which lives in ~/.MathWorks/ServiceHost/-mw_shared_installs/v2025.5.1.1/mci/bin/glnxa64 (obviously, the version might be different).
This discussion got me on the right way https://uk.mathworks.com/matlabcentral/answers/2176458-failed-to-run-matlab-gui-in-fedora-42 although the location of the installer has changed in 2025a.

I can confirm that on Debian 13, manually installing Mathworks' Service Host solved the issue for me, it is worth noting that before I was able to run the installer I had to install libgtk2.0-0; no further troubleshooting was needed.

Same for Ubuntu 24.04, clean install, it worked after having installed
libllvm20, libllvm20:i386
and upgraded
libegl-mesa0 libegl-mesa0:i386 libgbm1 libgbm1:i386 libgl1-mesa-dri libgl1-mesa-dri:i386 libglx-mesa0 libglx-mesa0:i386 libosmesa6:i386 libxatracker2 mesa-libgallium mesa-libgallium:i386 mesa-va-drivers:i386 mesa-vulkan-drivers
Before installations/upgrades the script InstallMathWorksServiceHost.sh has failed.
