After we upgrade from Karmic Koala Ubuntu then we face lots of problem in our system. Like every times upgrade and others problems. Moreover alpha release and other releases make more problems to your computer. So people would like to downgrade from Lucid Lynx to Karmic Koala. So for downgrading from Lucid to Karmic you need to visit here:
http://releases.ubuntu.com/karmic/
After that download the exact ISO file that matches your computer. And then make it boot able on your disk like USB disk, CD Drive. And then run the bootable drive by inserting during the booting of your system. That’s how you downgrade your Lucid lynx to Karmic Koala.
this is not 100% downgrading!
^ As far you know there is no downgrade or any sort of option. The downgrading can be done the clean installation. But as far the clean installation will remove all of your files, but it you select the installation path different then the system path and backup all your profiles and sources.lst, apt-files then this can be called a bit downgrade.
Actually, Admin, there is more of a true “Downgrade” then this and it does not require the download of an ISO file. See: https://help.ubuntu.com/community/DowngradeHowto
Lucid server is very buggy. USB hard disks dont work and there are “features” which make your machine hang during boot waiting for keyboard inputs. If i ever meet the developer who decided that was a good idea on a server he’ll wish he’d never been born.
A realistic option is to switch to Debian Server.

this seems to work only for minor version, how about major like 10.04 to 9.10 ?
anyone tested the script? i think it will create more mess than it is right now with 10.04 upgrade
