Installer hang when installing Matlab R2021b as root on Ubuntu 20.04

My operating system is Ubuntu 20.04 LTS. I must install Matalb as root, and always have done. This is historic as all specialist programs are installed in /opt.

I have now downloaded MATLAB R2021b and the Installer hang when installing Matlab R2021b as root on Ubuntu 20.04, the command sudo ./install just hangs with a blinking cursor, no Matlab install GUI is displayed.

As first attempted solution I have created a MATLAB/R2021b folder in /opt, that did not help.

I have also tried to install R2021b normally with defaults but although now I progress nicely to the Matlab GUI, but the default location /usr/local/MATLAB/R2021b cannot created/located and then I have to aboard.

I have always had to install MATLAB as root.

Any advice on getting the MATLAB install GUI to display on Ubuntu R2021b will be appreciated.

Thank you

I’m having the exact same issue. Ubuntu 20.04 , Matlab R2021b installer hangs after running sudo ./install

[Lorson Blair]

I'm also having this issue. Ubuntu 20.04.

[Steph Bredenhann]

I have been advised by Matlab Support "This appears to be an issue with MATLAB R2021b under root not being able to access the X Server". Workaround is to run the following command

xhost +SI:localuser:root

[Lorson Blair]

./install works without the sudo, but you are unable to reach the Matlab folder I created /usr/local/MATLAB/R2021b. This is obvious since I did not use root access.

[Lorson Blair]

The solution suggested by Step works. Run the command and then run sudo ./install.

[Jonnathan Ortiz]

It worked for me! Cheers!!

[Greg Chance]

Was having issue with this too, solution worked.

It seems to be working for me now!

[Yantong Wang]

It also works on R2022a! Awesome!

[Nikolaos Frantzeskidis]

Can confirm works without issues with R2022a on Manjaro. Thank you very much!

(run the command : xhost +SI:localuser:root)

and after

sudo ./install

worked for me (matlab 21b and ubuntu 20.04)

[Stephen Sangwine]

I tried this fix and it works. Ubuntu 20.04.2. R2021b.

[HUy Le]

It's worked

[omar elshazly]

it did not work for ubunto 18

[Vishesh Saini]

Thank you so much!

[Andrew Van Horn]

Tried this on Ubuntu 20.04 and it worked! This should be added to the install instructions. I wasted too much time trying to track down the problem.

[Cristina Lampón]

I had the same problem, tried this solution on Ubuntu 20.04 and it worked. Thank you!

[Johanphilip Davis]

I also had the same problem on Ubuntu 20.04. Currently, it is working. Thank you!

[Brenda Cyrielle Fochive Fewou]

It worked for me too thanks. But how do I get the short cut on the desktop please?

[Abhijeet Kishore]

Yes, it worked so smoothly. Thank you so much for your help.

[Michal]

Thanks for functional workaround! I spent a lot of time trying to solve this problem ... :(

[Olivier Alexander S Wartique]

Worked for me on Ubuntu 20.04 - Matlab R2021b

[Yusuf Oluwatoki Yusuf]

Worked for me too on Ubuntu 20.04 - Matlab R2021b

[ADITYA BHOPE]

Its of great help I tried to install but getting access issue

[Brian]

and what if i wish to install matlab on a system without a display/x server?

[Firat Soylu]

Thanks! This worked for me on Ubuntu 20.04 & Matlab 2021b after a fresh installation.

[창현 김]

Thanks.

[Kuan-Fu Wu]

Thanks. It worked for me on Ubuntu 20.04 with Matlab 2022a

[Wei Wang]

Thanks. It works for me on Ubuntu 22.04 LTS with Matlab R2022a

[Tiago]

Thank you! It works for me in Ubuntu 20.04.4 LTS and Matlab R2022a.

Answer 3

[Daniel Brennan]

I encountered the same problem with the installer hanging and unresponsive on a gentoo variant linux OS. For me the problem was related to incompatibilities with the system installed libsqlite3.so.0 library.

I discovered the problem by manually running the <installer_dir>/bin/glnxa64/MATLABWindow in a terminal. Running MATLABWindow manually resulted in the following error message echoed in the terminal:

libsqlite3.so.0: Undefined Symbol: ubrk_open

This error is due to an incompatibility with the system libsqlite3.so.0 library support for icu (Internationalization Components for Unicode) and the Matlab installer. The matlab installer apparently requires dev-libs/icu v69 or later. My system has v67.

The solution is to force the installer to use Matlab's builtin libicu support. For a source based distro simply recompile sqllite without icu support. On a binary distro, you may be able to temproarily remove the executable bit (chmod -x) on the icu libs in your system library directory, install matlab, and then restore the executable bit back on the icu libs after installation.

[Daniel Brennan]

Running:

ldd <installer-dir>/bin/glnxa64/MATLABWindow

will identify what shared libraries are being used and help identify any problematic libraries.
