Cant you use apt get?
sudo apt-get update
sudo apt-cache search adobe
(could be wrong, its been a while).
if not then you can either get the tar and compile from source, or get the .RPM and use alien to convert it - http://www.kitenet.net/~joey/code/alien.html
Says there is a deb package, so should be an ubuntu one.
Never taken the alien route so can't comment on the difference of ease between these 2 but apt get will be the easiest
