license error after updating Linux

Hi all,
I have been using Matlab R2016a under Linux using a concurrent license from my university. The system has been working very well until I have updated my operating system (I am now under Ubutnu 18.04). Now, when I try to run Matlab, I get the error:
License checkout failed.
License Manager Error -39
User/host not on INCLUDE list for MATLAB.
I know this has to do with the fact that the license server may not contain my username. However, this has always been working, hence my username must be in the list of allowed users. What I am gessing it's happening here is that after having updated the OS, Matlab is sending to the license server my OS user name (which obviously is not listed in the server, and should not be) instead of sending my Matlab username account (which is my university email address, and which therefore should be in the list of allowed users). How do I check this? Most importantly, how do I make sure that Matlab sens the correct username?
Thanks

(The official MATLAB description of error -39 was archived at https://web.archive.org/web/20161125120837/https://www.mathworks.com/matlabcentral/answers/98895-why-do-i-receive-license-manager-error-39 )

flexlm has never checked usernames by relying on MATLAB username .
A license access is authenticated under standard remote authentication protocols between the client and the server. Your username for the purpose of flexlm will be whatever you would be known as if you were to rsh or similar to the server. You do not even need to have a Mathworks account for this purpose.

I think at this point you would probably need to work with the IT department. They would be able to look in the logs to see what ID is being refused.
