Ubuntu 12.10 Quantal Quetzal Upgrade and Review
I recently upgraded to the latest version of Ubuntu 12.10 Quantal Quetzal from Ubuntu 12.04 LTS.
It was pretty easy to upgrade to Ubuntu. I used the Ubuntu Upgrade Manager, and change the settings to upgrade to "All versions of Ubuntu" instead of Long Term Release/LTS versions. All I had to do is agree to upgrade to Ubuntu, and wait for Ubuntu to download, and install the updates, and then I restarted my computer, and Ubuntu 12.10 was installed.
If you do not have a lot of free space on your computer, I recommend emptying your web browsers history, and moving your personal files to another hard drive, or to an external hard drive. You can also uninstall programs in Ubuntu which you no longer use. You can use the Ubuntu Software Center to uninstall programs.
Ubuntu 12.10 is similar to Ubuntu 12.04. I like the file search in the launcher lense in Ubuntu 12.10, and that it now displays images in the file search.
Ubuntu 12.10 now lets you pin web apps like Gmail, YouTube, Spotify, Ubuntu One, Amazon, and Yahoo mail to the launcher for quick access from the desktop.
Start computer from Ubuntu Linux 12.04 LTS Live USB Flash Drive
Many newer computers can start a computer from a Live USB Flash drive which has Ubuntu 12.04 preloaded on it. All you do is enter your BIOS/CMOS in your computer, and tell your computer to start from a USB flash Drive.
The Patriot Xporter XT Boost USB Drive is a great USB 2.0 flash drive for installing Ubuntu Linux 12.04 LTS on to because it is fast, durable and reliable.
You can also use a boot manager program which is like the BIOS, but it is only used for picking which device which you want to start from like a USB drive, CD, hard drive or floppy.
Finding, Installing, and Removing Software in Ubuntu Linux with the Ubuntu Software Center

The Ubuntu Software Center found in Ubuntu 12.04 and older versions is used to find, install, and remove software on Ubuntu Linux. It is similar to Apps stores for mobile phones and tablets like the Android Marketplace now called Google Play. It displays what apps are new, and which apps are top rated by the Ubuntu Community of users. Users can review, and rate app out of 5 stars which makes it easier for other users to pick apps to install, or not to install on their computer.
The Ubuntu software center can be found on the far left of your desktop in Ubuntu 12.04 or older. But, in Ubuntu 10.10 and older, it is found in the applications menu on the top right of the desktop.
All software in the Ubuntu software center is searchable, and categorized according to topic or subject, so finding software to install in Ubuntu is easy to do for most users.
To install programs in Ubuntu you use your mouse to click on the software which you want to install from your Ubuntu Software Center search results, or category. You can also read a short description of the software on the software page in the Ubuntu Software Center. If you feel it is the software you are looking for, click the install button on the far right, and enter in your administrative password which you made when you installed Ubuntu. Once installed, you can search for your software on the desktop search engine in Ubuntu 11.04-12.04 to launch it by searching for its name.
In Ubuntu 10.10 and older versions, you need to use the applications menu on the top right to launch it. You'll find programs are categorize into categories like games, office, and media.

If you used any computer operating system with a user interface made in the last ten years or older like Windows 95-7, Mac OS X or older, and other graphical based Linux operating system like Mandrake, RedHat, Fedora, Puppy Linux, Linux Mint etc, learning to use Ubuntu Linux is very simple since Ubuntu Linux also has an Application Menu, and Menus, icons, buttons, and shortcuts like most visual operating systems.
One of the best parts of using Ubuntu Linux 11.10 and older, is you can start your computer from its install CD and try it out before you install it on your computer drive. Installing Ubuntu Linux is easy for most computer users since it is a step by step wizard installer which ask you a few questions, and ask you to change a few settings before the install, and you just wait for it to install afterwards.
