Error while installing Dynare-Matlab in Ubuntu 18.10 (E: Sub-process /usr/bin/dpkg returned an error code (1))

I am trying to install the Dynare-Matlab in my Ubuntu 18.10 system. Installing Dynare worked fine. But when trying the Dynare-Matlab I receive this error message about an invalid user in Matlab.

sudo apt-get install dynare-matlab

Where I have XXXXXX is my university email address, from which I have my Matlab license. It did not ask me any information regarding licenses while installing. I don’t know how I should proceed. Any help would be highly appreciated.


PS: I use Matlab R2018b and would be happy to give further infos if needed.

@sebastien This seems like a question for you.

Dear @DoubleBass,

The problem comes from the fact that you gave your email address as the user (the XXXXXXX in the above log).

You should rather give your login on your Ubuntu machine (the login which has the needed credentials to run MATLAB). Note that all of this assumes that you have already installed MATLAB on your Ubuntu machine.

You can change the username by running the following on the command line:

dpkg-reconfigure matlab-support
