I installed mplayer using apt and about half way during the install in the terminal window it said something about an invalid key (and gave some number relating to it) and continued to install. The install finished, and appears ok. Afterwards I installed the mplayer plugin here http://freshmeat.net/projects/mplayerplug-in/?branch_id=43993&release_id=140487&topic_id=91 and and everything still seems fine. I am able to view windows and quicktime media. I am not use to using apt and was curious is it normal to see a message about an invalid key during an install using apt.
