I have the same problem.

I accidentally specified that the user would be 'root' as @Gary did but I got the following error when running matlab:

andrestoga@lap-ubuntu-andres:~$ matlab License checkout failed. License Manager Error -9 Your username does not match the username in the license file. To run MATLAB on this computer, you must run the Activation client to reactivate your license.

I also tried to run matlab as "sudo su matlab" as one in the following page suggested:

And I got the following error:

No passwd entry for user 'matlab'

Can someone help me please?

Best,

Ok, it works but typing first "sudo su" and then "matlab"

This a pretty old question. However, my work around was to install Matlab R2016b in a location accessible to the default (non-root) user (e.g. Desktop/MATLAB). Then launching matlab works fine for me.

I think it's just a conflict between users at time of installation/license creation and launching...

Ubuntu 18.04 Matlab 2019a :

The above problem arose for me when I gave host id in the existing license file as the host id with ethernet. In this case, Matlab starts only when connected to the same wired connection and throws error 8 / -9,57 when offline/connected to different wifi.

Solved the above by manually creating a license file from https://in.mathworks.com/licensecenter/licenses giving the host id which applies both with and without internet ( in my case, last entry of "ether" which can be found through "/sbin/ifconfig" in Linux terminal. Download the new file and paste its contents into existing license file. Then start matlab.
