Ubuntu 12.10 “Quantal Quetzal” has released, with a lot of new exciting features. So you’re running Ubuntu 12.04 LTS now, and you’re interested in the shinny features of 12.10, then you may want to upgrade now (or you can do a fresh install (12.10), in another partition/drive)
Upgrading to Ubuntu 12.10, from 12.04 LTS is very easy, but you must always have a backup of all your important data (to another hard disk or online such as Dropbox, Ubuntu One or Amazon S3).
First of all, Back up all your important data
Then, start Update Manager. Update the settings, so that it can notify you about the new version (by default it’s set for LTS only).
Now, restart the update manager and click on check to reload the package information. Now you should see the upgrade notification “New Ubuntu release 12.10 is available” at top.
Now, read the release notes and click on upgrade to start the upgrade process.
It may take time depending on your internet connection, once the process is complete, restart your computer and enjoy the cool features in latest Ubuntu release (12.10).
NOTE : If you prefer a solid and stable distribution over the new one with latest cool stuffs, then better stick with LTS version, specially in production environment or any situation where stability/compatibility is critically important. e.g in server environment. But for most of the desktop users, that might not be an issue, or you could run LTS as primary OS (for work) and the latest one as secondary OS in other partition/drive.
Ubuntu 12.10 has released with lots of new exciting features, but most users didn’t welcome the one feature which – integrates the amazon products in Unity dash serch results.

System Settings -> Privacy -> Include Online results in search -> OFF.

Unity is the default desktop environment, but if you’re not happy with it, then you can try some alternative desktop environments.

Unity is the default desktop environment in Ubuntu 12.10. Although, it has improved a lot but if you’re still looking for an alternative desktop with classic GNOME 2 style layout then you may try MATE.
MATE is a GNOME 2 based desktop, it’s easy to use, and the it’s stable too. it’s the default desktop environment in Linux Mint, an Ubuntu based distribution, more human-friendly for beginner users.
MATE Desktop environment is available for various platform, including ubuntu, fedora, etc. In Ubuntu, the best way to install MATE would be through the official PPA.
Open a terminal and execute the commands –
sudo add-apt-repository "deb http://packages.mate-desktop.org/repo/ubuntu quantal main"
sudo add-apt-repository "deb http://repo.mate-desktop.org/ubuntu quantal main"
sudo apt-get install mate-archive-keyring
sudo apt-get update
sudo apt-get install mate-core
sudo apt-get install mate-desktop-environment

Update! Fixed some errors!
PPA(Personal Package Archive) is great for installing new and cool apps/utils in Ubuntu or similar GNU/Linux distro such as Linux Mint etc. Due to PPA, publishing and distributing apps has become very easy.
Sometimes you may want to remove an application installed using PPA (may be because some sort of conflict occurred between the app installed from official repository and PPA) or may be you added a wrong PPA address and you get some error messages (on terminal, e.g file not found) or update manager is not working properly due to broken PPA etc. In that case, just follow any of the method (to uninstall the ppa) –
Removing a PPA address in Ubuntu 12.04/12.10/.. Linux Mint / similar_distro
Method #1. remove the ppa file(*.list) from
/etc/apt/sources.list.d directory. Open a terminal and execute the command
ppa_1.list ppa_2.list .... ppa_no_longer_required.list
sudo rm /etc/apt/sources.list.d/ppa_no_longer_required.list
Method #2. If the ppa contains a newer version of standard package, then you have to use the command –
sudo ppa-purge <ppa_address>
ppa_address will be in the format of
ppa:name/sub_directory (if required)
(so that it fall back to old version of the application as if there was no PPA)
Method #3. From Software Sources – go to
Ubuntu Software Center -> software sources -> other software (In Ubuntu 12.10, you can directly go to software sources) and uncheck the ppa you want to remove.
Finally, update the package cache, using the command –
sudo apt-get update
