Matlab 2021b crashed when running with sudo / root

I want to update my Matlab 2021b to update1. When running `sudo matlab`, the matlab kept crashed. All work well if I did not use sudo or root. Below is the crash report:

```

Answer 1

[Sivani Pentapati]

This is caused by a bug and our developers are aware about it and will try to fix it in future releases.

[Abdelkader Saad]

Any news? Can't run Matlab because of this issue and I need sudo access for my script to run. Purging and reinstalling fixes it for a run or two, then it starts again, it's not a sustainable solution.

Answer 2

[Francis Gagnon]

@Sheng Yang I have the same problem. FYI it's possible to update with the terminal by going to :

<matlabInstallPath>/bin/glnxa64/

and running :

sudo ./update_installer

If nothing shows you may need to run :

xhost +SI:localuser:root

before running the installer.

[Bryan Esser]

Thank you so much @Francis Gagnon!

xhost +SI:localuser:root did the trick for me

Answer 3

[Sebastian Kazmarek Præsius]

I had this issue as well. A solution was to run as "sudo -u USERNAME matlab", where USERNAME is the name of the non-root user.

[Madhurjya Kalita]

Thanks man you saved me :-)

Answer 4

[ubaid ur rehman ahmad]

Thanks,

Answer 5

[Kevin Moerman]

I have this in version R2022a and Ubuntu 20.04. Any solutions yet? @Sivani Pentapati

[Winston Zhang]

Same problem on R2022a and Arch. I was working until a week or two ago tho.
