11.10 to 12.04 Upgrade: My natural inclination is to go for the command line update method using:
do-release-upgrade
Any advantage or disadvantage to using the command line vs the graphical update process using update manager? Ubuntu's website recommends using update manager but I suspect this may be due to many user's aversion to using the command line.
I don't think so, both should do the same thing. only thing is graphical method is more suitable for people who are new or don't play with CLI much.
They both run the same commands under the hood, so you will end up with the same upgrade either way.
The main advantage of the command-line method is that it makes it easier to see any errors/warnings that might occur, so power-users can quickly fix them. The downside of that is that the specific errors are often confusing/scary, and the GUI method does a much better job of explaining things and how to fix them. The GUI method should be recommended for most people, especially new users.
