"Error: Unable to find installation candidates for these products" using ./mpm in command line terminal

Hello,

I managed to install MATLAB R2023b using ./mpm in command line terminal on my ubuntu machine. However, I am having problems with installing MATLAB_5G_Toolbox and other associated toolboxes (Communication_Toolbox, Signal_Blocks, Singal_Toolbox) using the same method.

The license is a Designate Computer, and when I open Matlab R2023 and run license, it recognises the correct license number for this license, so in terms of license it should be good.

However, when I close Matlab and run

'./mpm install --release=R2023b --destination /usr/local/MATLAB --products MATLAB_5G_Toolbox'

it complains 'Error: Unable to find installation candidates for these products: MATLAB_5G_Toolbox'. This happens to the other three toolboxes too. Even with 'sudo', it still doesn't work.

I expect when I run ./mpm, the programme fetches the installation from the internet and install the toolbox. But it does't work.

What's the problem here?

BR, Taihai

The command should be the following.

'./mpm install --release=R2023b --destination /usr/local/MATLAB --products MATLAB 5G_Toolbox Communications_Toolbox DSP_System_Toolbox Signal_Processing_Toolbox'

You can find the product names in mpm_input_r2023b.txt.

Thanks - it works.

Thanks again for the help @Kojiro Saito,

Please can I ask, if there's any way to uninstall the stuff that I just installed. The dir I would like them to be installed into is actually /usr/local/MATLAB/R2023b.

Also, as I have Matlab R2022b and the same toolboxes installed in /usr/local/MATLAB/R2022b. When both R2023b and R2022b are installed, if I run 'matlab' in any command line terminal, it would just open R2022b; when I do 'tab' after typing 'matlab', it dones't show up things like R2022b and R2023b as a list of arguments to follow. So what should I do here?

Currently, mpm command does not support uninstall. So, you can delete directory using Linux command.

I've found the hint from here.

The following remove /usr/local/MATLAB/* except for /usr/local/MATLAB/R2022b directory.

cd /usr/local/MATLAB
find ./ -mindepth 1 ! -regex '^./R2022b\(/.*\)?' -delete

Then, you can install with mpm again.

About matlab command, I think it is because of PATH environment. After reinstalling R2023b, you need to add MATLAB path to PATH.

For example of bash, the following command would work.

export PATH=$PATH:/usr/local/MATLAB/R2023b/bin

If you want to keep this environment variable, you need to add ~/.bashrc or some file.

Thank you.
