I have here in my launcher bar an icon which states that there are currently 418 available updates. Now I think people will appreciate that A That's a lot of updates and B It is not likely that an average user such as myself would know what most of these things do.
My basic fear is that by installing some of these updates, it is going to adversely affect things that are already running fine. I have already seen this happen with installing packages for LaTeX in Ubuntu.
So why not just leave well enough alone and ignore the updates?
Are there a few that would be particularly important that I should be aware of?
