Не удалось выполнить su или sudo после обновления с 13 до 14

Я обновил с 13 до 14, а в процессе обновления произошло много ошибок. Теперь я не могу получить доступ к root (через команду su) или выполнить что-то вроде sudo apt-get install something.

Если я пытаюсь:

    sudo apt-get install XXX

Я получаю эту ошибку:

    Errore di segmentazione (core dump creato)
    Segmentation fault (core dump created)

Как я могу исправить эту проблему?

EDIT 1:

Я просто попробовал aptdcon --fix-install в ответе здесь: segmentation fault при использовании su или sudo, и он вернул следующий результат:

ERROR: Operazione di pacchetto non riuscita

После этого я попытался запустить:

echo \"$(dpkg --get-selections | grep install | cut -f 1)\"

и

aptdcon --reinstall "package1 package2 package3..."

с помощью сгенерированного списка, возвращая следующий результат:
