KDE 3.5.6 released w Kubuntu packages

Folks:

I realize that upgrading to 3.5.6 shud be easy but........

After loading the key according to instructions
After adding the repository info to the sources.list according to instructions

None of my package managers shows a hint of KDE 3.5.6 packages.  No error messages.  So now I 
am scratching my head because I like stuff that purportedly fixes bugs.
