@sebastian-roth my colleague made me a joke by activating a second dhcp on a 4G terminal …

I managed to deploy!
but in debug mode.

I create an image in debug mode, then deploy in debug mode.

the default does not work:
error during deployment:

I also noticed an error on Ubuntu 13.10:
I jpgraph does not work properly. that is to say, no visible graphic.
