Hello,

when i try to check for updates with synaptic or the update manager, i
get that error above.  further information in the error message:

http://ftp.us.debian.org/debian/dists/lenny/updates/main/source/Sources:
404 Not Found [IP: 35.9.37.225 80]

i did try to change to different servers but i keep getting the same
error.  i think this installation is pretty standard, i haven't
customized it much.  here is my source.list:

$ cat /etc/apt/sources.list
# deb http://ftp.us.debian.org/debian/ lenny main

deb http://ftp.us.debian.org/debian/ lenny main
deb-src http://ftp.us.debian.org/debian/ lenny main

deb http://security.debian.org/ lenny/updates main
deb-src http://ftp.us.debian.org/debian/ lenny/updates main

deb http://volatile.debian.org/debian-volatile lenny/volatile main
deb-src http://volatile.debian.org/debian-volatile lenny/volatile main

# Backported packages for Debian Lenny
deb http://www.backports.org/debian lenny-backports main contrib non-free
$

let me know anything else i can check.

thanks
