Since the release date for Ubuntu 9.10 “Karmic Koala” is tomorrow I will show you how to quickly upgrade in a few simple steps.
First of all we have to do some prep work. Start the Terminal, you can get to it by clicking “Applications” -> “Accessories” -> “Terminal” and a Terminal Window will start. In the Terminal type:
sudo apt-get update
It is always a good practice to update the apt catalogue. Next it is also a good idea to download and install a updated version on the update-manager to do so type:
sudo apt-get install update-manager
Now that this is done we can go ahead and start the update-manager for the option of a Distribution Upgrade, to do so type:
sudo update-manager -d
this will bring up the update-manager.
Now you should see a new option “New distribution release 9.10 is available” and a Upgrade Button. Click on the Upgrade Button and the process starts with displaying the “Release Notes”. I recommend to read this first before you go ahead.
After you’ve done this click on “Upgrade” and the update-manager prepares your system for the Distribution Upgrade.
If you have Third Party Source in your source list like me then you will see this Message that they are disabled for the upgrade process.
Click on “Close” and the update-manager sets up the new software channels.
Wait a few seconds and the update-manager will show a list of packages whose support ended.
Acknowledge this and click on “Close”. Everything is now prepared and update-manager wants to know if you want to start the upgrade process, click on the Button “Start Upgrade”
Now the update-manager is going to download all new packages, this will take some time something between 30 – 60 minutes depending on your Internet speed.
right after the download the update-manager goes over to the installation of the new packages.
During the installation process the update-manager will ask a few question to the packages that will be installed. You probably won’t see all of those questions, so just disregard those. For the Grub installation just take the defaults.
also for the Postfix installation, just take the defaults
In this stage of the grub installation take the default that says “Keep local version currently installed” so as to cause no additional problems
and another question about grub, just check the installation Hard disk
now the installation process goes on for a few minutes
now the update-manager notifies you about an issue the the RPM Database if you have used it, just click on forward and go on.
you most likely won’t see this. I have an IPsec client installed and update-manager likes to know if it should keep or replace the configuration file. since I have the configuration altered I click on “keep”
I’ll do the same with this one here too and click on “keep”
now that the installation is complete the clean-up process starts
the update-manager want to know now if you would like to remove obsolete packages or not. Your choice!
Well done, upgrade is successfully completed. The last thing that needs to be done is to restart the system. If you did not experience any problems during the upgrade everything should be good and the upgraded system will boot up.
