I don't know how to solve this problem.

Google translates the error at the end of the Dpkg terminal log as:

An error occurred while processing the archive /var/cache/apt/archives/postfix_3.1.0-3_i386.deb (--unpack): dpkg:
  Subprocess new pre-installation script is a signal (broken pipe) terminated

After making sure the disk is not full (df -h), try:

sudo apt-get -f install

and see if it completes.
