Check whether the apt-get repositories inside /etc/apt/sources.list are resolvable and reachable. What is the error returned by apt-get?

it's going to be hard to provide a solution with the error message missing.

Shalom,

Could just be a temporary internet connectivity issue. Try again and post the error message?

Could also be that the package list is outdated and the package version cannot be found on the repository.

apt-get update will solve that.

But there's no way of knowing what the problem could be unless you atleast post the error message

I can't browse to internet as the server do not have gui mode installed .

I can't ping www.yahoo.com as the firewall is not allowed to ping

for DNS and route -n , I checked that all these settings in all servers is the same , but some server can use apt-get , but some can't , can advise what is the possible reason some server can't use apt-get ,

p.s. they are in same server farm , same segment .

If your machine cannot connect to the internet it can't download the files via apt-get either unless you have a internal mirror.

Depending on what your sources.list says you're probably using either of http or ftp.

1) You can try to ftp to a external ftp site to see if you're allowed to do that.
2) You can use wget, curl or lynx/links to surf to a webpage.
3) You can use nslookup/host/dig to check if you're allowed to do DNS lookups properly.

This is ofcourse unless you have full access to your firewall and can check what's allowed or not.

Also if you have set up any IPTables rules that might be a source of error.
(iptables -nvL will list all iptables rules set in FORWARD, INPUT, OUTPUT and also any chains that is built)

Your system is not correctly connected to the internet, so it won't work. This can be concluded from the message:
> "Could not resolve 'ftp.hk.debian.org'"

Fix the machine until 'dig ftp.hk.debian.org' gives back a valid IP address. After that you can try again to have apt-get working.

Hmm. This topic certainly was sleeping for quite a while.
Note that success with "dig" or "host" may not mean that apt-get will succeed for host lookup.
If a proxy is specified by http_proxy environment variable or by a config file in /etc/apt/apt.conf.d/ then the proxy system would actually be doing the DNS lookup.
