This has nothing to do with Canonical, but with availability from other sources. Did you by any chance try to install fglrx from the ati website or from a PPA?
With apt-cache policy <packagename> you can check which version is installed on your system and which version is in the repositories.

As you can see in the ubuntu repositories both are version 8.960, the 9.002 is only in my list because I installed it in the past from the ati website.
EDIT: You can check which version you have installed by
dpkg -l | grep fglrx | grep ii
or if you installed without using the package manager
cat /var/log/Xorg.0.log | grep fglrx | grep -A4 'Kernel Module Version Information'
