I have been using beta1 release of Ubuntu 12.04 (Precise Pangolin) since last few weeks and I have been trying to setup Ubuntu Server pool for one of my critical application which requires HA (High-Availability) and Load Balancing.
But today I am not going to talk about what I have been building on top of ubuntu but ubuntu precise has come up with new and final development release (beta2) today before production ready release, which will be available on 26th April (probably last week of April 2012).
I am new to Linux but Ubuntu has made my experience so rich (even without any GUI) that I am feeling bad about using Windows so far. Everything seemed so easy with handy commands and world was all here. I fell in love with Ubuntu and I will keep using it for the good.
Now Ubuntu 12.04 Precise has many good features which I am not going to jot down here but you can view that on official posts.
How to upgrade to Ubuntu 12.04 / Precise Beta2 from 11.10 or 11.04 ?
To upgrade from 11.10 you just need to use "sudo apt-get do-release-upgrade -d" and it should take you on ride with precise. Here switch "-d" indicates that you want to upgrade to development release.
How to upgrade to Ubuntu 12.04 / Precise Beta2 from 12.04 Beta1 ?
To upgrade from 12.04 beta1 to beta2 you need to use "sudo apt-get dist-upgrade". I didn't knew that but I came to know once I asked at ubuntu-forums.
Want to download Ubuntu 12.04 Beta2 ISO?
For all those who don't want to upgrade but want to download fresh ISO and try it on their VMs, please download it here.
Thanks to the Ubuntu Community (software for human beings) from the Happy User and Admin. I have learned lot of things in past couple of weeks which I will be sharing in upcoming posts.
Update: Mark Shuttleworth, Ubuntu Linux’s father, is proud of where Ubuntu is going and thinks that the next version will bring real desktop user experience innovation “before it shows up in Windows or MacOS.” - After Ubuntu 12.04 first beta release.
