I am trying to run the Matlab R2013b installer on Ubuntu Server 12.04 64 bit, and although the installer itself runs fine, it does not accept keyboard input at any stage during the install. I am unable to type in my MathWorks credentials, a license key, or the location of a license file, which is preventing me from upgrading my Matlab install. I have tried installing both with and without an Internet connection with the same result. I have also tried copy-and-pasting the necessary information into the installer window, (using both the right-click context menu and keyboard shortcuts) which also doesn't work. The installer script does not appear to have a working text-only mode. How can I resolve this?

Also happens on xorg with LXDE under Ubuntu 16.04 for me (R2020b).
Highly annoying. If this also happens in GUIDE based Apps or the Matlab AppBuilder stuff this is a no go

Routinely experience this on Fedora 33 with gnome. The keyboard locks, not just in the installer, also in the software when working.
Typically the problem starts when you interact with GUI elements with the mouse.
To unlock the keyboard, select another window (e.g. the browser), select a text input (e.g. the address bar), and switch back to installer.

Can confirm that this worked for me while installing R2021b. but still I wonder why it failed to bring attention of Matlab dev.

A Mathworksrep answered this in another thread, like this:.
This is a bug on RedHat distributions that locks out your keyboard. To work around this issue, select the "File Installation Key (FIK)" radio button and then toggle back to the "login to MathWorks Account" button. You should now be able to enter your account information.

On release 2021a, the toggle back is to "standard install".
