   • http://packages.ubuntu.com/lucid/misc/ndiswrapper-common
   • http://packages.ubuntu.com/lucid/ndiswrapper-utils-1.9
   • http://packages.ubuntu.com/lucid/ndisgtk
   Additionally all the three packages You can download from here: ndiswrapper.tar.gz.

   • sudo dpkg -i ndiswrapper-utils-*.deb
   • sudo dpkg -i ndisgtk_*.deb
