Debian - cannot execute binary file: Exec format error - How to reinstall a package. [SOLVED]

This morning I tried to capture the traffic on Debian server and got an error:

debian# tcpdump -i eth0
-su: /usr/sbin/tcpdump: cannot execute binary file: Exec format error
debian#

Apparently this server experienced a problem with local disks and file got corrupted so I had to reinstall the package:

debian# dpkg --purge tcpdump
debian# apt-get install --reinstall tcpdump

Good luck!
