Error with installing matlab to server

I followed this guide https://medium.com/@ananyaagrawal125/install-matlab-on-ubuntu-18-04-b4403b489b4d

I get all the way to executing the install

i type sudo ./install and get

"

terminate called after throwing an instance of '(anonymous namespace)::DisplayError'

what(): No display available.

Aborted

"

and now if i just type in ./install instead of sudo ./install I get the same error

"

terminate called after throwing an instance of '(anonymous namespace)::DisplayError'

what(): No display available.

Aborted (core dumped)

"

Why cant i run the install file on the server?
