Administrative rights (need to know password) on the Dell Mini and internet connection (WiFi or Ethernet).
Download three package (.deb) files from Betavine . (Windows machine used and files copied to empty USB memory stick.) Certainly, these three .deb files (ozerocdoff_0.4-2_lpia.deb, usb-modeswitch_0.9.7_lpia.deb, and vodafone-mobile-connect_2.10.01-1_all.deb, at staging.betavine.net, last mod July 04 2009), are the ones to have.
Right-click on each file in turn and select 'Open with GDebi Package Installer' (Memory stick used to show files in File Browser on Mini.)
Of the three files, the vodafone-mobile-connect package depends on the ZeroCD and USB Device Switch packages that have no dependencies, so install the connect package last.
The Package Installer does the business excepting errors. And, when installing USB Device Switch, there is the error 'files list file for package `libxcb-shape0' is missing final newline'. This is a reported bug with the suggested workaround to remove the list file and rebuild the package. Terminal commands are: cd /var/lib/dpkg/info sudo rm libxcb-shape0.list sudo apt-get --reinstall install libxcb-shape0 Result is download of replacement file(s) and fixing-up of the package. (And error free installation of USB Device Switch package.)
Right-click the package file vodafone-mobile-connect_2.10.01-1_all.deb and install with GDebi Package Installer. (Error free with the ZeroCD and Device Switch packages installed.)
After installation of the software packages, select the Dell desktop and see 'update in progress' before desktop is displayed with the new Vodafone icon.
