UPDATE 3: You can download the Ubuntu 12.04 Manual from here
UPDATE 2: 9th May 2012 – Thanks to the Ubuntu community, I managed to fix the postgresql 8.2 error using command “sudo touch /usr/share/postgresql/8.2/tsearch_data” and removed the postgresql without any errors. Then I started to upgrade again (not using the Update Manager which still showed errors but using Terminal command) and this time, upgrade was rather smooth (perhaps thanks to the stable internet connection). The upgrade to 12.04 LTS was finally done after almost two hours. The review of the 12.04 will be done later if I have time.
UPDATE 1: 27th April 2012 – the upgrade from 11.10 to 12.04 LTS had hiccups when the upgrade package download connection was disconnected half way (due to my internet connection) – the same did not happen when I upgraded from 11.04 to 11.10. When I retried the upgrade, the update failed to work. After a few tinkering, I found the source of the problem – postgresql 8.2 was corrupted and need to be removed. Easier said than done, the removal failed as follows:-
Reading package lists… Done
Building dependency tree
Reading state information… Done
The following packages were automatically installed and are no longer required:
libmagick++3 amsn-data libemeraldengine0 perlmagick inkscape tcl-tls
Use ‘apt-get autoremove’ to remove them.
The following packages will be REMOVED:
0 upgraded, 0 newly installed, 1 to remove and 660 not upgraded.
After this operation, 12.4 MB disk space will be freed.

Mark the launch date – 26th April 2012. This is the date when Ubuntu will be releasing their latest OS – version 12.04 codenamed “Precise Pangolin”. I have been using Ubuntu 11.04 for sometime now (suppose to upgrade to 11.10 a long time go but my OS update was screwed due to a silly mistake of mine – somehow I have “un-ticked” the upgrade source server).
And of the things that I am looking forward to in 12.04 is the possible inclusion of HUD. OMG!Ubuntu reports “HUD – Heads UP Display – uses an intelligent search-based approach to finding and accessing menu items you need. It’s smart too; HUD is capable of remembering what items you use most often and prioritizing them in the results. The goal is to make finding menu items faster, in turn speeding up your workflow”.
(HUD in action hopefully in the upcoming Ubuntu 12.04 and never misjudge the ease of using keyboard shortcuts and hotkeys instead of using the usual mouse clicks. As I have experienced, it can very, very fast and very convenient)
- Unity Dash’s default home screen has changed. Now, it shows ‘Recent Apps’ first, ‘Recent Files’ next and lastly, your most recent Downloads.
- Home menu quicklist is a really useful addition
- Apart from the usual three Unity lenses (Applications, Files and Music), there is now an additional Video lense too. It lets you select and play videos from a variety of sources ranging from your local collection to YouTube Movies, BBC iPlayer and TED Talks to name a few.
- HUD is now an integral part of Ubuntu 12.04 Precise Pangolin. HUD have not yet replaced menus in applications though. So no need to panic.
- Size of launcher icons can now be changed directly changed from ‘Wallpapers’ menu. No need to install CCSM just to do that anymore. As you can also see, there is now an option to change the default Ubuntu 12.04 theme from the same window. Useful additions and nicely done too.
- This is perhaps the biggest visible change to new Unity. Launcher won’t be in the ‘dodge windows‘ state anymore (by default) and instead will be ‘always visible’. Dodge windows is not even an option anymore. It is completely removed.
- Initiating Alt + Tab shows you just the open windows in the current desktop and not from all the desktops like it used to be
- The decision was taken during the last Ubuntu Developer Summit (UDS). Rhythmbox has just replaced Banshee in Ubuntu 12.04. Note taking application, Tomboy, has also been removed. Canonical seems serious about completely removing Mono from Ubuntu.
Those who have not used Linux before, the new release of Ubuntu may be uneventful. But installing free, open source Ubuntu as my secondary OS (having Ubuntu and Windows in dual boot) was probably one of the smartest I did when I upgraded to a 64 bit machine a couple years ago (I was curious and wanted to brush up on Linux as well).
This is because when I was abroad for an assignment last year and when my Windows crashed unexpectedly (due to a registry screw up – what else?), all I needed to do was to fire up my Ubuntu and was still able to connect to the Internet to check my emails using Firefox, chat with my colleagues using Pidgin & Skype, open documents & spreadsheets using the free Libre Office and use OpenProj for project management, etc – well you get my drift. What I am trying to say here is that with Windows crashing down (and the only way to fix the crashed Windows was to reinstall Windows all over again – duh), it did not mean the end of story for me.
Linux are not like those days when you have to run most of the apps using line command in Terminals (you still do sometimes but it is not difficult once you get hold of the usual convention) and where a simple update of packages was a nightmare. But now, thanks to user friendly GUIs, software center with well-stocked apps and well organized update manager, it is in par and in some cases superior to Windows 7. You also don’t have to worry about firewalls and anti-virus in Ubuntu and best part is, it is also free and can run along with your Windows without much fuss.
I have moved from 10.10 to 11.04 (which introduced Unity user interface which combines search and dock functions in one) and finally to 11.10 (which refreshed the login screen with LightDM and tweaked the Unity to be more streamline. It felt lighter too), I can’t wait to move to 12.04 next week.
