sudo apt-get install を使用してパッケージをインストールできない

今日設定したRaspberry PiでRaspbianを実行しています。問題は、パッケージをインストールしようとするたびにエラーが発生することです。たとえば、sudo apt-get install samba は次のように表示されます。

The following packages have unmet dependencies: 
libc6 : Depends: libgcc1 but it is not going to be installed 
samba : Depends: samba-common (= 2:3.6.6-6+deb7u4) but it is not going to be installed
        Depends: libwbclient0 (= 2:3.6.6-6+deb7u4) but it is not going to be installed 
        Depends: libacl1 (>= 2.2.51-8) but it is not going to be installed  
        Depends: libattr1 (>= 1:2.4.46-8) but it is not going to be installed  
        Depends: libcap2 (>= 2.10) but it is not going to be installed  
        Depends: libcomerr2 (>= 1.01) but it is not going to be installed  
        Depends: libcups2 (>= 1.4.0) but it is not going to be installed
        Depends: libgcc1 (>= 1:4.4.0) but it is not going to be installed  
        Depends: libgssapi-krb5-2 (>= 1.10+dfsg~) but it is not going to be installed  
        (...)
Try 'apt-get -f install' with no packages (or specify a solution).

だから私はsudo apt-get -f installを実行してみましたが、結果は次のようになります。

 $ sudo apt-get -f install

その後、これらの新しいエラーを修正する方法を見つけようとし、最終的に次のような結果が得られました。http://www.raspberrypi.org/forums/viewtopic.php?f=28&t=48737

だから私は次の手順に従います。https://askubuntu.com/questions/55099/dpkg-error-parsing-file-var-lib-dpkg-available-near-line-0

他の人にとってはうまくいったようですが、それでも同じエラーが発生するため、パケット管理に問題があるようです。この問題をどのように解決できるかを知っている人はいますか？
