C2000 Microcontroller Blockset install fails silently on Ubuntu 20.04

I am trying to install C2000 Microcontroller Blockset on Matlab R2025a. The final install dialog box tells that MATLAB will resart after installation is complete. MATLAB NEVER RESTARTS. I have tried this many times.

Matlab Version: '25.1.0.2973910 (R2025a) Update 1'

I have CCS 12.81 an 20.4 installed on my system which is running Ubuntu 24.04.3 LTS.

How do I proceed ?

Hi Sarthi,

I assume you install matlab in a sudo-required location, for example the default location, correct?

If so, MATLAB tries to run the installer but since it needs sudo, it fails silently. You can try:

• Run MATLAB as sudo first, then install via the Add-ons.
• Use other installation methods, such as running the MATLAB installer or using MPM.

You are using Ubuntu 24 (and 25 I believe), there is a bit of an issue launching MATLAB using sudo, it'd crash. You'd need to rename/move the library libstdc (eg /usr/local/MATLAB/R2025a/sys/os/glnxa64/libstdc++.so.6.0.30) so MATLAB uses the system's library, then launching sudo wouldn't crash.

The second option, I suggest reading this article:

My Matlab is installed in my home/MATLAB directory. I believe this directory doen't require sudo.

Also, I've done a complete reinstall of the software during which C2000 blockset was installed.

Hmm I see, then perhaps the installer failed due to some other reason and not permissions.

You could take a look of the installation log if it happens again, it should be in /tmp/mathworks_*.log where * is the username.
