Ubuntu: the sudo ./install does not work for Matlab

138 views (last 30 days)
So i have treid both ways. Using the sudo ./install and going to the root with sudo su. Both dont open the installer for Matlab.
If i just type ./install its runs. But the problem is i cant install it in the usr/bin directory. If i install it in the ~/user/ directory it does not open.
Any ideas :/

What I did was the following, I open the folder on terminal and then use
1 - sudo su
2 - ./install
Btw I am on manjaro not on ubuntu, but probably will work.

I (partly) confirm the same problems to install R2021b as a root. On Linux (latest Kubuntu 21.04). Exactly following the same installation procedure used successfully dozens of times with previous versions.
After unzipping (unzip matlab_R2021b_glnxa64.zip), typing sudo ./install in a terminal does nothing (prints nothing but the process hangs and needs to be killed after a few minutes of waiting).
Typing just ./install and choosing some user directory gets the installation running and the installed Matlab can be launched without problems.

This answer, although marked as "accepted", is hardly a "solution".

  1. (run the command : xhost +SI:localuser:root)
  2. sudo ./install
works for me for Ubuntu 22.04 LTS and Matlab R2022a

You have to transfer your Xauthority session and display to a different user (root) then run ./install or sudo ./install.
For example on a Linux system:
xauth list $DISPLAY
should return something like:
host.domain.com/unix:10 MIT-MAGIC-COOKIE-1 dacbl57583ec54a1d7115a172143926aa
then run the command:
echo $DISPLAY
which should return something like:
localhost:10.0
then switch to a root shell:
sudo su (sudo su -, or sudo -i, or whatever your preference to get a root shell)
and based on YOUR results from the above commands:
xauth add host.domain.com/unix:10 MIT-MAGIC-COOKIE-1 dacbl57583ec54a1d7115a172143926aa
(this will be whatever was returned from the above xauth list $DISPLAY command)
export DISPLAY=localhost:10.0 (this will be whatever was returned from echo $DISPLAY)
Then when you run .install as root it will install wherever you want it to install with root permissions.

Thanks. I was both in a hurry and assumed too much. I think I've fixed it up.
