Обновленный от 14,10 до 15,04, после перезагрузки никакое изменение

Я использовал Ubuntu 14.10 (ПОМОЩНИК Ubuntu), и мой Менеджер обновлений разоблачил это существует обновление, возможное к 15,04. Таким образом, я выбрал хорошо и запущенное обновление. Потребовалось много времени, но после этого все было закончено, и я должен был перезапустить систему.

Но теперь все - то же. Нет никакого изменения. Я проверил ядро с uname -a , но это - старые 14,10 ядер, я думаю:

Linux i3 3.16.0-38-generic #52-Ubuntu SMP Thu May 7 10:51:21 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

Я запустил менеджер обновления также sudo apt-get dist-upgrade но нет никаких новых обновлений. Существует что-то подозрительное? Какие-либо идеи?

Править: возможно, этот вывод может помочь для анализа:

Я вижу 3.19 там - но так или иначе когда начальная загрузка моей системы все еще использует 3.16, почему?

Редактирование 3:

lsb_release -c
Codename:   vivid

Почему это ярко, если даже ядро не корректно?

Редактирование 4:

Хорошо sudo apt-get install linux-generic действительно решал проблему. После этого я перезагрузил, и теперь у меня есть текущее (?) ядро:

uname -a
Linux i3 3.19.0-18-generic #18-Ubuntu SMP Tue May 19 18:31:35 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

Я все еще не понимаю, почему моя система использовала старое ядро после обновления 15,04 (возможно, кто-то может объяснить?), но я надеюсь теперь, что все прекрасно. Спасибо за помощь!
