From the original set of scripts made by mdelfede (Massimo), dolik.rce (Honza) has prepared an only script (dvn+stable included) that works well for my Ubuntus and also from an empty system, so thanks to them I am happy to close this topic (from my side)
From now on there will be 32 bits .deb files in the SourceForge releases (every 2-3 weeks).
Best regards and thanks to Massimo and Honza
