Ok...
Installed Sozi in easy-debian First inskape and had to download Sozi-deb and installed through Debian-Chroot (it wasn't in repos?)

tried a little it last a litle bit to start (inskape) but then it's preaty usable I think. Dind't tried Sozi extention yet as soon as I can nd learn a litle about the use I'll give my impression.
Thanks
