I recently had a Windows apocalypse happen to my computer, and I could no longer boot up with Windows. So, a few years ago, a former IT manager installed Unbuntu when he partitioned my computer. I have not used it, just briefly. Now I am booting up in Ubuntu and I have some catching up to do. My major question is this: I have version 9.04 Jaunty Jackalope with GNOME and I was going to upgrade, but read that you can't just jump to the newest version, but you must go through all previous versions until you get to the newest (prerequisites).
Is this true?
Also, I have 1GB RAM, lots of space though. Are the newer versions of Ubuntu okay for an older system?
Thanks for any help! I have used Sun/UNIX quite a bit, but this is my first real experience with LINUX.
