For the purpose of this question: Catalyst = fglrx = proprietary AMD/ATI display driver

The most problems people are having come from the fact that:
1. Ubuntu has moved to newer driver versions, that don't support some older ATI/AMD chips
2. Ubuntu has moved to newer Xorg versions

Symptoms:
No. 1 - 'not supported' errors / Jockey not detecting proprietary drivers valid for installation
No. 2 - some older ATI/AMD Catalyst versions won't install

Which all comes down to:
Your chip is no longer supported by the latest ATI/AMD catalyst display drivers (be it via manual install or from Ubuntu repositories)

Solution:
Check, what is the latest driver version that supports your chip and then proceed with the installation accordingly.
