ubuntu 9.04 update manager unable to read package information

[Kevin S]

Binary package hint: flashplugin-nonfree

Ubuntu 9.04:
adobe-flashplugin (Adobe Flash Player plugin version 10 (Size: 3.0MB)) shows up in my Update Manager when it gets loaded.
However, when I went to update my packages, it said something about it not having the right packages... (I'm not sure exactly, because that message is now gone).
It wouldn't let me check the box next to it, to include it in my updates to install. Now it has greyed out the option entirely. I can't click on the adobe-flashplugin entry at all, and yet it remains in my Update Manager.

This is not a big concern for me, it just recommended that I report it, and so I am...

Thanks,

...
Kevin.
