Ubuntu 9.10 and error when installing Adobe Air

I tried install Adobe Air. All cases with the error alert:

An error occurred while installing Adobe AIR. Installation may not be allowed by your administrator. Please contact your administrator

But these steps helps:

1. in synaptics remove broken package adobeair
2. sudo rm /opt/Adobe -R
3. sudo rm /etc/opt/ -R
4. sudo apt-get remove adobe-certs
5. sudo dpkg --purge adobe-certs

I got it :) Adobe Air installed on karmic koala.
