update/upgrade_error

[Vram]

Why do I suddenly get these errors?

W: Couldn't stat source package list http://archive.ubuntu.com
hoary-updates/main Packages
(/var/lib/apt/lists/archive.ubuntu.com_ubunty_dists_hoary-updates_main_binary-i386_Packages) - stat (2 No such file or directory)
W: Couldn't stat source package list http://archive.ubuntu.com
hoary-updates/restricted Packages
(/var/lib/apt/lists/archive.ubuntu.com_ubunty_dists_hoary-updates_restricted_binary-i386_Packages) - stat (2 No such file or directory)
W: You may want to run apt-get update to correct these problems



And running apt-get update  does not solve the problem


Thank  YOU
