Linux : Installing new toolboxes on an existing installation

Hello,

I want to install toolboxes on an existing installation, for example on :

/usr/local/MATLAB/R2020b

as suggested by the matlab installer.

I tried to select the toolbox with the add-on button on matlab windows, connect to my account, and then I got a problem because I don't have the permission to write on /usr/local/MATLAB..

I tried to run matlab with a command line as sudo like :

sudo /usr/local/MATLAB/R2020b/bin/matlab -c /usr/local/MATLAB/R2020b/licenses/license.lic

And I got a licence checkout failed:

License checkout failed.

License Manager Error -9

Your username does not match the username in the license file.

I haven't the intaller script anymore, or don't know where it is located on matlab installation folder (/usr/local/MATLAB/R....)

Does anyone knows how to solve this ?

Thanks in advance,

Bruno

You should be able to use the AddOn manager to install additional toolboxes.

Edit:

With default settings, Matlab is installed as root in /usr/local/MATLAB/, so unless you're running Matlab as root, you will not have write access. One way around this is to set the permission to the user:

sudo chown -R $USER /usr/local/MATLAB/

Now the user has write access and you can use the AddOn manager. After installing the toolboxes, revert the permission change with this:

sudo chown -R root /usr/local/MATLAB/

Obviously you need to change this path if you installed Matlab in a different location.

I think the best solution would be to attempt to fix the licence error. As you may have guessed, my Linux prowess is a bit limited, so I don't know specific causes without Google. The specific error might help. I know Walter Roberson has compiled a list of licence errors and a pausible cause+solution.

You might also try to set the rights to a normal user. I can imagine that might have unintended consequences though.

Unfortunately, there is no "solving of that error". The installation was made for a user ID, if that ID does not match the one that the license is trying to check out, you will keep getting that error.

The solution proposed above is neat!
