Apt-Get Repos not found

I’m running Ubuntu Server 13.04 (raring). I imported the key and added the lines to the repo
deb http://repo.percona.com/apt VERSION main
deb-src http://repo.percona.com/apt VERSION main
replace the VERSION with raring and and when I update i get a 404.
“Failed to fetch http://repo.percona.com/atp/dists/raring/main/binary-amd64/Packages 404 not found”
then the line for i386
http://repo.percona.com/atp/dist/raring/main/binary-i385/Packages 404 not found.”

I followed the pdf. What is the proper line to add to the repo? Assuming if the repo is there?

I realized that even though it says can’t find repo. if you then run following command it will install.
sudo apt-get install xtrabackup

I guess you have a mistake in your source.list. Check the url that apt is trying to get:

http://repo.percona.com/atp/dists/raring/main/binary-amd64/Packages

It has “atp” instead of “apt”. It should be:

http://repo.percona.com/apt/dists/raring/main/binary-amd64/Packages
