http://askubuntu.com – I'm completely new to Ubuntu 11.10 oneric ocelot desktop i386 plus no internet connection. I have a freshly install of Ubuntu and I want to install ClockWorkMod tether to have internet connection thru my smartphone(via USB), but in order to do that, I need to run a .sh file. I have readed online that I need a bunch of things to install it, like build-essential, g++ compiler... and a lot of things. I would like to download all software needed on Windows (I got windows 7 and Ubuntu 11.10) and installed using a usb thumb or a cd, since I got internet connection on Windows. What's the best(easi (HowTos)
