@Jiregna

When you are entering the new username in the activation client, you must use your Windows username

The best way to resolve a License Manager Error -9 is by reactivating MATLAB with the activation client.

Linux

The activation client is located here:

/usr/local/MATLAB/R20XXx/bin/activate_matlab.sh

Once you have launched the MATLAB activation client:

Select "Activate automatically using the internet."
Log into your MathWorks account.
Select the correct license.
The username field should auto-populate with the correct user name. Leave it as is.
Confirm the activation information.
Click "finish" to complete the activation process.
Restart MATLAB.

I hope this helps you out.

@Khelifa

/home/kbaizid/.matlab/R2022b_licenses is the folder that would typically be used to hold individual licenses for username kbaizid

/usr/local/MATLAB/R2022b/licenses/license_IITxxxxxxx.iit.local_4XXXXXX_R2022b.lic would probably be for a Designated Computer license for license number 4XXXXXX installed on hard disk with serial number IITxxxxxxx but I guess it could potentially be an individual license.

Anyhow, look at the locations listed and delete any R2022b license file you find there (well, unless you have multiple people using the same machine, then be more careful.) Then run the activation client in the MATLAB installation directory.
