[kepler-users] Kepler -nogui execution without X11GraphicsEnvironment

[Ramón Pérez Pérez]

Hi,

I think that it is possible that there are new modules to download for your version, and for this reason the execution (too in command line) tries to launch the X11. We changed the configuration.xml in kepler_2.2/module-manager-2.2.0/resources/configurations as follow:

<?xml version="1.0"?>
<config>

    <releaseLocation>
        https://code.kepler-project.org/code/kepler/releases/released/
    </releaseLocation>

    <check-for-patches>false</check-for-patches>    

</config>

Best,
Ramón
