The problem was the software to manage network connections on squeeze, as said Kovid "network manager" is needed for Calibre to manage the internet connection. Nowadays I've my Squeeze unmaintained, a problem with a misconfigurated grub2 is preventing the access to my debian. And with the job I have, travelling so much over the province of Toledo (Toledo from Spain, not Ohio
) I've no time to maintain my old recipes, my old debian squeeze...
