Я не могу обновить, обновить и удалить свое приложение из kubuntu

У меня проблема с обновлением программного обеспечения. Я не могу обновить, обновить или удалить свое программное обеспечение.

Уведомление диспетчера обновлений подписывает 46 пакетов безопасности и 83 других пакета, и когда я нажимаю на них, чтобы установить их, появляется другое окно и пишется:

Не все пакеты могут быть помечены для обновления. Доступные обновления могут потребовать установки или удаления новых пакетов. Вы хотите пометить обновления, которые могут потребовать установки или удаления дополнительных пакетов?

И у меня есть две возможности:

Отметить обновления или нет

Независимо от моего ответа я получаю два окна ошибок:

Первый из них:

Я попытался запустить:

sudo apt-get update

а потом

sudo apt-get upgrade или sudo apt-get dist-upgrade

но

Когда я бегу sudo apt-get updateэто результат: http://paste.ubuntu.com/1468542/

Когда я делаю "sudo apt-get dist-upgrade": http://paste.ubuntu.com/1468859/

Как я могу решить проблему?

Редактировать:

Читая об ошибках, я подумал, что проблема может быть в Ubuntu-связке ключей. Я искал в ask.ubuntu и нашел эту ссылку: Проблемы с обновлением системы с помощью apt-get

и я попробовал:

:~$ sudo rm -r /var/lib/apt/lists/*
:~$ sudo apt-get update

Вот результат: http://paste.ubuntu.com/1475133/

а также:

:~$ sudo apt-get upgrade

Вот результат: http://paste.ubuntu.com/1475136/

Edit2:

Я посмотрел на ошибку, и я догадался, что, возможно, ошибка в libreadline. Я спросил что-то об этом здесь: https://dba.stackexchange.com/questions/31143/libreadline-so-6/31177

И в конце я удалил файл, я успешно обновил системы, но когда я перезапустил систему, удаленный файл все еще был там. Так что проблема остается.

Большое спасибо за помощь
