Wow new Ubuntu, as said on the site perfect Ubuntu 10.10 (Maverick Meerkat) is now out :D. I could not resist myself from upgrading to it even I am using Ubuntu Lucid Lynx on Macbook Pro 7.1. I am upgrading specially to know whether it also works fine on Macbook.
Upgrading Ubuntu is always easy and fun. All you know that. However, if there are someone who does not know it, here it is. Just run the following command from terminal when you are online:
sudo update-manager -d
Then it should automatically detect that a new version is available. Just click on Upgrade button (show on the image above) when it appears. Follow instructions on screen and then sit relax while it is upgrading for you. However, carefully notice the alert (before main phase starts) it provides which includes the packages are going not to be supported anymore, packages that are going to be deleted etc.
Enjoy and pray for me so that it works fine on Macbook :P. I will write detail experience with it later.
