Failed installs of RSS reader

[Ollie Killingback]

I am really grateful for the suggestions for alternatives and have
installed the Sage extension for Firefox which does the job very well.

However, I need to learn!  I'm good with Windows and I want to be good
with Fedora.  So what I really need is to understand the results I got
from following up Nicola Losito's suggestion that I posted earlier.

Help with this would be very much appreciated.  I look forward to the
day when I can answer questions as well as ask them.
