Hi all,
I am using debian sarge as desktop. My posotion is behind proxy, and internet connection is ok.
But when I issue command
apt-get update to update my system I got output like bellow
And I do not know what is the problem with my proxy server,.....I found that error 502 means the proxy is overloaded, but I alwazs got this error, but in other hand I can take packets ....I just take ethtool look below.

Any opinion?

try changing /etc/apt/sources.list to
ftp://ftp.hr.debian.org/

I tried as you suggested me, but nothing happened, i got the same output as I posted in my previous post.

Anyway thank you for your help

regards

FTP connections will not work with a pure HTTP proxy server.

You probably have to configure apt-get to work with pure HTTP servers. (or) check to see if you have configured your proxy server to work with FTP.

You have set the environment variable http_proxy (via export) or have you put an Acquire::http_proxy in apt.conf?
