Hi,
What is the easiest way to upgrade opensuse 10.2 to 10.3?

I generally prefer slapping in a Kubuntu disc and saying "screw it"...

But...if you're big on OpenSuSE, I'd have to say having a separate home directory and just doing a fresh install has always treated me kindly.

You can use YaST to do the upgrade, but I really wouldn't suggest that for at least a week or two after the new version comes out, as the servers get hit so hard, people constantly have time-out issues and then start blaming the "new version" as being unstable, when in fact, it's just their rush to be first in line to play with it.

If it's been longer than a week or so, just use YaST, things should work out just fine unless you have some weird 3rd party software in the mix - this can lead to dependency issues, and if that's the case, re-read my first 2 suggestions.

Cheers,
Ghost

How exactly do i use YaST to upgrade? Can you please give a step-by-step explanation to a newb?

If you are a newbie, I think you should use the cd/dvd sets to do and upgrade or clean install. An upgrade will leave your /home and config files intact. If /home is on a separate partition, a clean install may be better. Just make sure you do not format /home at install time. Upgrading a live system using YAST is possible, but you may have to deal with a lot of dependency issues. To do this, you need to change your YAST sources so that they point to the latest openSUSE version and then do YAST -> Software Management -> Filter -> Package Groups -> zzzAll, right click on a package and choose to upgrade all installed packages to a new version.

do not forget to deactivate packman and other additional sources before an upgrade via yast. you should only have activated the opensuse10.3 repositories to avoid conflicts....

Can anyone please provide the specific url needed for 10.3 upgrade sources?

I don't know exactly. just google "opensuse 10.3 upgrade repositories" or directly go to the opensuse page...

You need to use the installation sources listed on the openSUSE website (opensuse.org). I don't think they have installation sources specifically for upgrades.

there is a tool called factory upgrade which could also do the same in yast....
