“In line with its newbie-friendly tradition of providing a way
to do everything via a graphical user interface, Ubuntu provides a
way to do a distribution upgrade by clicking a button at the top of
the Update Manager. Since version 10.04 was released on April 29,
it was once again time to see how well the upgrade went. Here are
screenshots of the entire process. (Click the images for larger
versions.)“Although most Debian gurus recommend doing a dist-upgrade of
this magnitude (i.e. upgrading from one release to another) at the
command line, without the X server running, that just wouldn’t
be…easy enough for Ubuntu. It’s a risky process, even when done
at the command line. Just one small error in an installation script
can lead to things getting broken. I’m happy to say that I
encountered no problems.”
