With the release of Ubuntu 10.10 (Maverick Meerkat) you may be wondering how to upgrade your previous version of ubuntu . If you have a good internet connection you can go for the network upgrade and if you don’t have a direct access to the internet I have the solution. But here’s my condition : manage to download 700MB of upgrade data using workplace internet connection.

Before the upgrade:

  • Have at least 800MB space available in your Ubuntu file system.
  • Please note that you CANNOT  jump versions when doing an upgrade. You can’t upgrade directly from a version below 10.04.(For versions below 10.04, say 8.04, the upgrade should be done incrementally this way: 8.04 to 8.10, 8.10 to 9.04, 9.04 to 9.10, 9.10 to 10.04, 10.04 to 10.10).If you have a similar condition, it’s better to just get the latest CD and install from scratch.

Let’s get started:

Step 1: Get the CD

Get the ALTERNATE installation CD here. See that you got the ALTERNATE version (most likely – “ubuntu-10.10-alternate-i386.iso”) and not the desktop version.

Step 2: Burn the CD

If you run out of cd’s you can very well mount the iso file. First copy the image to your desktop. Then go to terminal and type:

sudo mount -o loop /home/user name/Desktop/ubuntu-10.10-alternate-i386.iso /cdrom

NOTE: Replace the “user name” in the command with your original user name

If your downloaded file name is different, replace “ubuntu-10.10-alternate-i386.iso” with your file name in the above command.

Tip: If you run into low space error, bring up a terminal and run the following commands to clean junk files from previous upgrade or updates:

sudo apt-get clean
sudo apt-get autoclean
sudo apt-get remove

Step 3: Upgrading

You will see a pop-up window that says: “A distribution volume with software packages has been detected”.
If upgrade dialog doesn’t pop-up, type this on the Terminal to open the upgrade window:

gksu "sh /cdrom/cdromupgrade"
 OR
kdesudo "sh /cdrom/cdromupgrade"(for kubuntu users)

Follow the instructions on the screen. Upgrade will still take some time.

Step 4: The “Test Ride”

Now you are ready to go with your new ubuntu 10.10

In case you experience difficulties in upgrading your ubuntu please let me know.
