I seem to have gotten into the habit of writing a post each time I do an upgrade, so here is the one for Ubuntu 14.10. It's really easy - by far the simplest upgrade I can remember. This, I'm sure, is partly because the changes behind the scenes this time are more about stability than new features but it's a welcome change. Nothing, and I mean nothing has broken for me either on my desktop install or this laptop.
I can't say I'm immediately noticing many improvements either, other than the latest packages. Not that I'm complaining - mostly, an obvious improvement means a change and frankly I like Ubuntu 14.04 enough as it was that it didn't need another overhaul to make me happy. Some minor bugs have been ironed out - the big one is that it no longer randomly forgets my keyboard language preferences.
So, don't fear this one. For me, this is the perfect upgrade - nothing broken and no major changes to learn.
