HAProxy Installation problem

[Paladinemishakal]

Hi,

I am installing HAProxy on Debian Etch and got this error when trying to get the packages from Lenny.

----------------------------------------------------------------------

This is my apt sources.list
------------------------------------------------------------
deb http://ftp2.de.debian.org/debian/ etch main
deb-src http://ftp2.de.debian.org/debian/ etch main

deb http://ftp2.de.debian.org/debian/ lenny main

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

This is my apt preferences
----------------------------
Package: *
Pin: release a=etch
Pin-Priority: 700

Package: *
Pin: release a=lenny
Pin-Priority: 650
----------------------------

Can I still proceed with the HAProxy installation according to the instruction? What is the problem with the error?

Regards.
