thanx in advance.

Clean up your folder /var/cache/apt/archives: aptitude clean
and then aptitude autoclean..

This will wipe all .deb packages dowloaded and installed in your system. IT will keep growing so you need to clean it every once in a while. Use aptitude instead of apt-get..It is more powerfull.

Then: aptitude update

Hope it helps..

From the beginners:Is not this something be wrong? gedit /etc/apt/sources.list /etc/apt/sources.list.bt : -|

Some answers for the above scenarios:

1. If apt-get says it fails to connect to the repository but nslookup is working:

1.1: Nslookup doesn't tell you if the domain is up, only what ip the domain has, it sends its query to the DNS server, no to the domain.

1.2: Most likely you use a proxy. In my experience, apt-get doesn't honor http_proxy envirorment variable.
You have to write folowing settings in /etc/apt/apt.conf

Aqcuire::Http::Proxy "yourproxy:port"

2. If apt-get says it fails to auhtenticate the packages it downloaded:

2.1: The gpg key from the repository could have an expiration date. I didn't check if it's true for the backtrack repository.
To check it, type to the terminal:

gpg --list-keys

Most likely your system date and time is wrong. Check your system date&time.
