Hi,
I am an assistant of Giorgio Pioda.
I noticed that on fresh reinstalled (PXE method) Jessie Workstations there is a duplicate line in the /etc/apt/source.list file.
In fact there are two "dev
http://http.debian.net/debian/ jessie main non-free contrib" lines, and this causes problems when installing new packages and updating.
In attachment a screenshot of the situation.
