Lets try to build some answers here. I think this is one good scenario to think about, it can happen to any pilot flying big jets. So, if it does what are we gonna do?

The correct answer was already posted by Mysha Da Kat. Shut down.
At that point you would have completed half of your flight assignment. Worry about the other half afterward.
In the A319/A320 FCOM, there is a limitation of 3 APU start attempts followed by a 1 hour interval. The APU is normally started while taxiing in. If it fails to start twice, it's probably a good idea to wait until just before parking before the third attempt. If it still won't start, shut BOTH engines down, let the passengers off, dump the cargo, and wait an hour before trying to start the APU again.
You can use the one hour interval to coordinate with maintenance, local station management, and the like. You should also develop a full contingency plan for your RON just in case the APU is truly inop. Everyone has extra clothes in the bottom of their nav bag per company standard, right?
