aptを使用してパッケージをインストールできない

Debian 6 サーバーに大きな問題があります。システムにパッケージをインストール/削除できません。何かをインストールしようとすると、次のエラーが表示されます。

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 consolekit : Depends: libglib2.0-0 (>= 2.37.3) but 2.24.2-1 is to be installed
              Breaks: udev (< 204-1) but 164-3 is to be installed

私が試したときapt-get -f install：

dpkg: considering deconfiguration of sysvinit-utils, which would be broken by installation of startpar ...
dpkg: no, sysvinit-utils is essential, will not deconfigure
 it in order to enable installation of startpar
dpkg: error processing archive /var/cache/apt/archives/startpar_0.59-3_amd64.deb (--unpack):
 installing startpar would break existing software
configured to not write apport reports

Errors were encountered while processing:
 /var/cache/apt/archives/startpar_0.59-3_amd64.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)
