sudo ./install on linux silently fails R2022a

AFAIK this has been an issue since R2021b (maybe before?)

Running ./install doesn't have the permissions to install to /usr/local/ but running the install script as sudo hangs and fails silently.

To me, this is a pretty serious bug for linux users, I was hoping it would be fixed in this new release. Has this been logged internally at MathWorks?

This has been discussed previously, e.g. https://uk.mathworks.com/matlabcentral/answers/1470321-sudo-install-doesn-t-start-on-linux

I have been advised by Matlab Support "This appears to be an issue with MATLAB R2021b under root not being able to access the X Server". Workaround is to run the following command:

xhost +SI:localuser:root
