packages.debian.org الان که دارم این رو می نویسم down هستش.این پیغام رو میده :
packages.debian.org is down at the moment due to performance issues.

We apologize for any inconvenience and hope to have service restored as soon as possible.

We're working on resurrecting this service but it will take some time.

You can use apt-file, apt-cache search and findpkg (--> Google) as a temporary replacement.
