I'm current using Ubuntu 8.04 and have no internet access.Please tell me how can I have a full update by USB stick ?
I hope it'll a simple way, just simply download a file and install on the Ubuntu PC.
Thanks

You can at least make a CD and upgrade:

http://www.ubuntu.com/getubuntu/upgrading

Check the section on that page called "Upgrading Using the Alternate CD/DVD"

I'd recommend making a CD and using that, as opposed to putting it on a USB drive. It seems like booting from a CD will be much simpler.

If you must boot the Alternate CD from a USB drive, please check: https://help.ubuntu.com/community/Installation/FromUSBStick
