My normal upgrade process is to wait at least a month after an Ubuntu release 
before I do my upgrade. Gives them a chance to iron out the glitches that 
always come with a new version.

8.04 is old enough now that it's well established and ought to be pretty much 
rock solid. In fact, 8.10 is due for release this week, so 8.04 certainly 
isn't on the bleeding edge any more.

It's possible that you meant to say 8.10, in which case, I for one am going to 
wait it out for a bit longer, and if you're nervous about the upgrade, I'd 
recommend waiting a bit too. But if you meant 8.04, I'd say it should be 

That said, it is sensible to take precautions -- you should always take a 
backup of everything important before you start (and make sure it's 
recoverable), and if possible, have an installable copy of the old OS to hand 
just in case you do have problems with the new one.

There will always be exploitable bugs with every kernel and every OS. Linux 
isn't immune, and when they get found and fixed, that's a security update.

As long as you keep your machine up-to-date with all the latest patches, 
you'll be fine.

Hope that helps.
