sudo ./install command not found for ubuntu installation

I'm trying to install matlab 2022a on a virtual machine instance running ubuntu 18.04. When I go run the install file, I get an error that sudo ./install: command is not found. I've tried this in and out of root mode and adding localuser:root to control list. The install file is definitely in the matlab directory.

I've also tried using sudo sh ./install

This causes it to hang indefinitely and not progress.

For anyone else interested, it worked without using sudo
