Обновление с 18.04.1 (бионический) до 18.10 (космический) завершается неудачно

Я пытался выполнить обновление с помощью средства обновления программного обеспечения, но окно загрузки после загрузки файлов было закрыто. Затем я попытался обновить с do-release-upgrade но это также не удалось без явного сообщения об ошибке.

Я установил все обновления и перезапустил перед попыткой обновления. Что-нибудь еще, что я должен проверить?
