I looked at the command:
<#apt-get install pkg-mozilla-archive-keyring> and really studied it and compared it to deb-multimedia.
So I tried typing in the terminal:
<#apt-get install pkg-deb-mulimedia-archive-keyring> the terminal returned:
Unable to locate pkg -deb-multimedia-archive-keyring
So I tried again only this time I eliminated the words pkg and archive and it worked.
I ran <#apt-get install deb-multimedia-keyring> it worked and afterwords I was able to run apt-get update!
What really helped me was this page:
http://deb-multimedia.org/
Eairlier in the thread you advised me to look up mv and cp.
mv file1 file2, mv -i file1 file2, and mv dir1 dir2 and cp file1 file2, cp -i and cp -R dir1 dir2
I found the rule for all 3 ways to use move and all 3 ways to copy and wrote them down.
Once I use these methods a few times I'm pretty certain I will have the gest of it.
This was helpful Evo thank you
I've also learned from you that there is more than one way to communicate with the terminal.
