apply quota patch to postfix

i'm installing quota patch for the postfix on debian lenny, however i cannot get the postfix source code to apply the patch

each time i try
apt-get souce postfix

i get the message:
E: Could not open file /var/lib/apt/lists/ftp.debian-unofficial.org_debian_dists_lenny_main_source_Sources - open (2 No such file or directory)

how can apply patch to postfix then?

how was that? =.=

 

Can you run

Code:

apt-get update

and try again?

 

well, before getting started with the guide, I run 'apt-get update' then 'apt-get upgrade' to make sure that everything is up2date

but still i doesn't work =.=

 

What's in /etc/apt/sources.list?

 

here is the content of /etc/apt/sources.list

Code:

#
# deb cdrom:[Debian GNU/Linux 5.0.0 _Lenny_ - Official i386 CD Binary-1 20090214-16:29]/ lenny main

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

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

# added

# general packages for lenny
deb http://http.us.debian.org/debian lenny main contrib non-free
deb-src http://http.us.debian.org/debian lenny main contrib non-free

# unofficial

deb-src http://ftp.debian-unofficial.org/debian lenny main contrib non-free restricted

# multimedia

deb-src http://www.debian-multimedia.org lenny main

 

Looks ok.
What's the output of

Code:

ls -la /var/lib/apt/lists/

?
