Why was succession a problem for the roman empire?

The succession problem has two components: skill succession and power succession. In public discourse and political thought we have tried to solve either power succession or skill succession under different names. We seamlessly switch between two separate fragmented states of mind depending on which facet of the problem is in front of us without even noticing. Please give me the brainliest answer?

Since the Roman Empire was new at the time of the Julio-Claudians, it still had to work out issues of succession. The first emperor, Augustus, made much of the fact that he was still following the rules of the Republic, which permitted dictators. ... Instead, the Romans had to work out the rules of succession as they went.

"states can make their own laws, as long as they don't contradict what the federal law states. the states do not have the authority to pass a law that negates a federal law." -google
