Can't install Flash plugin for Firefox

[ZuLuuuuuu]

Hello, I was trying the preview version of Fedora. I wanted to watch Youtube videos but couldn't install the Flash plugin. I have done the things here:

http://docs.fedoraproject.org/release-notes/f8/en_US/sn-Desktop.html#sn-Enabling-Flash-Plugin

After installing Yum repository for Adobe I found the Flash plugin. But when I try to install it, Yum says:

"A security trust relationship is not present

GPG key F6777C67 required"

My system is updated. I then tried to install Gnash. But it was not able to display the videos (just a black screen).

How can I solve this problem?

If you are sure that you have a 32bit version of Firefox installed, it should really be easy. The repo is already setup, if you did the tutorial setup ..

In a Command line console, just

yum install flash-plugin.

and

yum info firefox

should only return one instance of Firefox...
this work for me every time. If not....
do a
SmotlSendProfile.... paste the link here, and then we know what you have on your box.... maybe the help will then be a bit better..
:D

I had the same problem, but following these instructions solved everything :
Enabling flash plugin (http://docs.fedoraproject.org/release-notes/f8/en_US/sn-Desktop.html#sn-Enabling-Flash-Plugin)

I have updated my system today. And the Flash installer worked :) Thanks for the replies...
