I’ve been using Ubuntu from 7.10, and always is the same… download the image and burn a CD, which after 10 days (at most) is nothing but trash.
The solution is to `burn’ the iso file in a USB. HOW? there is a Ubuntu package called usb-creator
$ sudo apt-get install usb-creator usb-creator-gtk
which after install might be called from the terminal using the commamd,
The advantage of the USB besides save nature by allow us to trash less CDs, is that the live version is much faster than its CD partner, and the recycling makes easier to try the developing releases… for example two days ago I tried the beta2 version of Lucid Lynx… and the improvement from beta1 is notable, specially stability.
Nothing more to say, just enjoy life!
