If the usual upgrade works for you, follow it - the steps here were done because the regular upgrade didn't work (slow internet connection, and some more problems).
Info: I'm running 32-bit Ubuntu, inside Virtualbox (a VM) under Windows XP SP3 host.
Note: These are the steps that worked for me. I can't guarantee that they will work on your system, and you should know what you are doing. ALWAYS BACKUP BEFORE UPGRADING!
- Go to the Update Manager (under System->Administration) and install all the updates (except for the new Ubuntu version) by clicking the Install Updates button.
- Download the Ubuntu Alternate Installation CD iso file (I downloaded it by torrent from here). Now, either burn it on a CD and then insert the CD, or mount it directly if you know how.
- A dialog should pop - Choose the upgrade option. If a dialog does not pop, run the cdromupgrade program (inside the root directory of the cd) as root (using sudo).
- When it asks about using the network, say no. This will allow us to install directly from the cd and not from the web (which is slower - that's why we downloaded a torrent in the first place)
- You may get the following error:
An unresolvable problem occurred while calculating the upgrade:In that case, close the upgrade process. Open a console and type
Can not mark 'ubuntu-desktop' for upgrade
This can be caused by:
* Upgrading to a pre-release version of Ubuntu
* Running the current pre-release version of Ubuntu
* Unofficial software packages not provided by Ubuntu
If none of this applies, then please report this bug against the 'update-manager' package and include the files in /var/log/dist-upgrade/ in the bug report.
sudo apt-get remove ubuntu-dektop
Now, repeat from step 2 (inserting the CD). You may get an error saying that a required package ubuntu-desktop can not be installed. Ignore it (as if you have a choice :D)
- The installation should now begin!
Note - you may get a dialog or two asking you about replacing some configuration files, towards the end of the installation (8 minutes from the end in my case). Make sure to look once in a while to see such dialogs that need answers.
When the installation will finish, you are probably going to get error messages about gnome-orca not being installed correctly. We'll fix these in a moment.
- When the installation is done with/without errors, restart your machine if it hasn't done it by itself.
- When the machine is up again, make sure the ubuntu installation CD is still mounted. Open the console and type:
sudo apt-get update
- If you had any errors during the upgrade (i.e. it said that it finished, but with errors), run the following command:
sudo apt-get -f install
If you are using Virtualbox, then like after every serious upgrade, you'll need to re-install the guest additions from the guest additions CD. Here is where the fun starts - they don't work on Ubuntu 10.10! Luckily, the unixmen website explains how to fix it - see this article explaining how to install the guest additions.
Note: you may need to upgrade the version of your Virtualbox after installing the guest additions as described in the above article.

*Update: You will need to run the update manager again - System->Administration->Update Manager. If it complains about some partial upgrade, click the button that says to complete the partial upgrade.
