small update and install problems!
 

hey!

every time i am install updates or add some application on Ubuntu, the first thing system allerts that-

W: Couldn't stat source package list http://archive.ubuntu.com breezy/main Packages (/var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_breezy_main_binary-i386_Packages) - stat (2 No such file or directory)

...then i hit Ok and the updating or installation proceed sucsessfull and everything is ok.

but why system is making such allert?
