What's the difference between Ubuntu 12.04 LTS for free and the Official CD of Ubuntu for $5? I didn't know the difference.
When I boot Ubuntu 10.04.3 from a live CD, it asks me to enter a username and password. I have not booted before, and I haven't created an account.
I've just downloaded a CD image of Ubuntu. I know the installer has a check CD option, but how can I check that the image is good before burning it to CD?
I have a fair number of older Ubuntu CDs sitting around for releases that are not supported anymore. They have beautiful pressed labels and sleeves that I would hate to just throw away.
What can I do with them?
What are some alternatives to upgrading without using the standard upgrade system? Suppose for example that I wanted to upgrade an Ubuntu installation on a machine with a poor Internet connection. What would my options be? Could I just use a standard Ubuntu disk to upgrade this machine? If I already have a standard Ubuntu disk and want to use that, could I do a clean install without wiping data?
