Обновление проблемы

Позвольте мне поблагодарить Вас заранее за чтение и попытку помочь мне.Спасибо! Извините за ужасное редактирование также должен был изменить некоторые ссылки, потому что я не уважаем :)

Моя проблема как такова: Открытие центра программного обеспечения Update ошибочное окно кажется говорящим: "Объекты не могут быть установлены или удалены, пока каталог пакета не восстанавливается..." Я нажимаю восстановление, но оно перестало работать.

выполнение sudo склонный - добирается, обновление перестало работать, это - сообщение об ошибке:

"W: Failed to fetch archive.ubuntu.com/ubuntu/dists/precise/Release  Unable to find expected entry 'restricted/source/Sources' in Release file (Wrong sources.list entry or malformed file)

W: Failed to fetch bzip2:/var/lib/apt/lists/partial/us.archive.ubuntu.com_ubuntu_dists_precise-updates_main_binary-i386_Packages  Hash Sum mismatch

E: Some index files failed to download. They have been ignored, or old ones used instead."

Я попробовал: чтение других ответов подобных и выполнения, что они предложили:

1. изменение сервера я использую

2.

    sudo apt-get autoclean
    sudo apt-get autoremove
    sudo apt-get -f install

3. следующее не работало также:

    cd /var/lib/apt
    sudo mv lists lists.old
    sudo mkdir -p lists/partial

Помогите мне askubuntu, Ваша моя единственная надежда! Еще раз спасибо
