Guide: Upgrade Ubuntu from 12.04 LTS Precise Pangolin to 12.10 Quantal Quetzal

Hey folks,

Ubuntu 12.10 with the codename Quantal Quetzal was released yesterday. I am very excited to go through the neccesary steps for the upgrade. You guys who might be thinking about an update will be shown exactly what the process will look like. I will be using the „desktop“ tools to upgrade within the Unity environment. More tech savyy users might want to use the console only.

First, make a backup of all your stuff. I tend to save the whole home partition to an external disk in order to make sure all my data is in a safe place. I’ve made very good experiences with upgrading Ubuntu but I will not bet my data on it.

So, let’s go!

First make sure you’ve got your current Ubuntu installation updated to the most recent version. Start the „Update Manager“ of Ubuntu.

Ubuntu Upgrade Step 1

Click „Check“ first and „Install Update“ if you’ve got anything left to install. You might be promted to reboot your machine to let all updates take effect. Please do so, to make sure anything will work smoothly. Once everything is installed, reopen the Ubuntu „Update Manager“.

Ubuntu Upgrade Step 2

If your settings are the default one, you will not be able to see the new Ubuntu 12.10 Quantal Quetzal update because the current one (being an LTS, long term support, update is only looking for new LTS releases). So under the tab „Updates“ choose Notify me of a new Ubuntu version „For any new version“.

Ubuntu Upgrade Step 3

Now you will be able to see the Ubuntu 12.10 Quantal Quetzal update. Click on „Upgrade“.

Ubuntu Upgrade Step 4

You will be greeted with some information. Click „Upgrade“.

Ubuntu Upgrade Step 5

Ubuntu will now prepare for the upgrade and determine which packages have to be updated for your specific system configuration…

Ubuntu Upgrade Step 6

Once it has done that, you’ll be promped with the result. Most important is the estimate it will take Ubuntu to download all the files needed for the upgrade. Just click „Start Upgrade“.

Ubuntu Upgrade Step 7

Now, you can grab (several) mugs of coffee… depending on the speed of your internet connection and your hard drive. I’m fortunate enough to have a fibre channel internet connection so the download will only take several minutes.

Ubuntu Upgrade Step 8

After the download, Ubuntu will start installing the updated packages onto your system. This will take some time depending on the speed of your hard drive or SSD. To monitor the process even closer, you can just flip out the terminal.

Ubuntu Upgrade Step 9

Ubuntu Upgrade Step 10

It took my machine over an hour to install the fresh packages (2,2 Ghz Core 2 Duo Laptop, with 3 GB of RAM, 250GB HDD). Finally, you’re asked if the unneccessary packages can be removed. Proceed with „Remove“ (if you want that).

Ubuntu Upgrade Step 11

Ubuntu Upgrade Step 12

You’re almost done. Time for the final reboot!

Ubuntu Upgrade Step 13

Congratulations! You’ve successfully updated you machine to Ubuntu 12.10 Quantal Quetzal!

Ubuntu Upgrade Step 14

One more thing: There is lots of discussion going on because if you search for something in Unity’s menue, you are always exposing your search terms to Amazon and get shopping results based on that. If you want to protect your privacy open up „System Settings“ from the launcher on the left and click on „Privacy“.

Ubuntu Upgrade Step 16

Then switch off online search results. If you really want to make sure, you can uninstall the Amazon search feature. Open up the „Terminal“ and enter:

sudo apt-get remove unity-lens-shopping

Confirm with typing in your password and typing „Y“ when asked.

Now, have fun with your freshly upgraded Ubuntu 12.10 installation :) Let me know what you think of my upgrade guide and of course of Ubuntu 12.10 in the comments section.

Tip 1: Additional Drivers program

May I suggest you also add a tip for those looking for the Additional Drivers program if they have driver problems. It is now integrated as a Tab in Software Sources. [ Accessible from Software Updater>Settings and System Settings.]


Thanks to .☠. from for his feedback!
Tip 2: Ubuntu 12.10 release notes

Imho you should link to the release notes of Ubuntu 12.10 at the beginning of the article. There are a few ‚known issues‘ which you should be aware of before upgrading.
