[PLUG] Upgrading Adobe Flashplayer in xUbuntu-10.4

[Rich Shepard]

   Apparently, the flash player installed with xUbuntu-10.4 is rather
outdated. My wife wants to watch a thing or two that complains she doesn't
have the latest Adobe P**** O* S*** ... er, flash player ... installed.

   She tried using Synaptic package manager but doesn't see how to upgrade
what's already installed.

   We'd appreciate pointers to step-by-step instructions on how to get the
latest flash player installed on her laptop.

Thanks,

Rich
