Recently I upgraded my OS from Ubuntu 10.10 (Maverick Meerkat) to 11.04 (Natty Narwhal). But I am having problem installing some software in the latest version from Ubuntu Software Center. Because the Ubuntu 11.04 Partner repository is not ready properly with all packages. I did a little hack here. After that, I have followed the following steps and installed those software.
Just open terminal and type the following line
Click on the “Other software” tab and then click on the “Add” button. Finally, add the following line
deb http://archive.canonical.com/ubuntu maverick partner
Some software may have compatibility issues. But still now I did not face any problem to installing software from Ubuntu 10.10 Partner repository.
