Matlab home doesn't start due to licenseing error: -9,57

I just installed MatLab Home R2017a on Ubuntu 16.04 on my desktop. Activation was done as discribed in the Installation Guide. But when it comes to the point of entering the user name I entered my User-Id of the MATLAB account. - How can I fix it? - What exactly is the User-Name with Ubuntu? Only the account on the machine? Or the account @ machine name?

You can deactivate and activate again manually in terminal.

For deactivating, go to $MATLAB_INSTALL/bin and do

./deactivate_matlab.sh

where $MATLAB_INSTALL is installed directory of MATLAB.

Then, to activate again, do

./activate_matlab.sh

Username is just an account name of Ubuntu machine.

The username you should use should be the same as is reported by whoami at the shell level.

[Sai Akanksha Punuganti]

Yes.You can solve this error by typing the user-name you have typed previously in the same computer.

Works fine for me. Had installed the licenses in /usr/local/MATLAB/R2016b/license/ owned by root.

Deactivate the license and reactivate it on my username "foo".

@Kojiro Saito: Thanks and it worked in my account on our ubuntu server. However, our server is shared by many people. Though every one has access to MATLAB academic license, how to configure the matlab so that each user can use it with their corresponding username?

Activating the account with one user name defaultly removes access to people with other usernames in the same server.

Do we have to make multiple installations and activations?

[Kojiro Saito]

@Prasanth Thangavel How about using Designated Computer License on that server? I suppose you're using individual license on that server so activation is allowed for each username.

Please write step by step for me.

[Walter Roberson]

Ubuntu 18.04

1. Open a terminal window
2. command whoami to get your username.
3. in the terminal window, cd to the MATLAB bin installation directory
4. in the terminal window, sudo ./deactivate_matlab.sh
5. in the terminal window, sudo ./activate_matlab.sh
6. At the point in activation where it asks for the name of the user who will run MATLAB, respond with the username you got from whoami
