The flash player is indeed in the Ubuntu repository. If you already have it and it is not working then I would speculate that you are using 64 bit Linux. The last time I ran 64 bit Linux, earlier this year, I could not get Flash to work. I'm back to using 32 bit Linux specifically for this reason.
I watch YouTube and other multimedia web sites all the time. The only thing I cannot get to work is NetFlix streaming movies. It requires Microsoft Silverlight. (blaggards!)
