На этот вопрос уже есть ответ здесь:
Я новичок в Ubuntu. Я пытаюсь загрузить Okular pdf reader из Центра программного обеспечения, но получаю некоторую ошибку. Сначала он запрашивал установку пакетов из неаутентифицированного источника, когда я нажимаю на Использовать этот источник , он идет и делает что-то вроде
обновления кеша
Затем через некоторое время он показывает мне эту ошибку:
Я прочитал этот вопрос «Требуется установка ненадежных пакетов?» и попытался восстановить кеш, как указано в первом ответе, используя:
sudo apt-get clean
cd /var/lib/apt
sudo mv lists lists.old
sudo mkdir -p lists/partial
sudo apt-get clean
sudo apt-get update
и получил это вывод:
yogeshwardancharan@ubuntu:~$ sudo apt-get clean
[sudo] password for yogeshwardancharan:
yogeshwardancharan@ubuntu:~$ cd /var/lib/apt
yogeshwardancharan@ubuntu:/var/lib/apt$ sudo mv lists lists.old
yogeshwardancharan@ubuntu:/var/lib/apt$ sudo mkdir -p lists/partial
yogeshwardancharan@ubuntu:/var/lib/apt$ sudo apt-get clean

E: Some index files failed to download. They have been ignored, or old ones used instead.
Затем я попытался переустановить Okular, но снова получил те же ошибки. Я попытался изменить источник программного обеспечения на Главный сервер , а также включил аутентификацию для сторонних источников программного обеспечения, но все еще без прогресса.
Ubuntu 12.10 не поддерживается больше с мая 2014. Любой необходимо обновить к более свежей версии Ubuntu (т.е. 14.04) или найти альтернативный репозиторий. Альтернативный репозиторий для 12,10 выпущен здесь (благодарен за то, что @rubo77 находит его). Больше информации об обновлении может быть найдено здесь .
Как 12,10 EOL, repos для него переместились. Обновите до более новой версии человечности (или понизьте до 12,04, хотя это действительно не рекомендуется) получить доступ к нормальному repos. Если абсолютно необходимо использовать ту версию человечности, рассмотреть добавление архива repos, Google для получения инструкций относительно того, как сделать это. В конце мой ответ является обновлением 14,04, это более стабильно и имеет поддержку
