Обновлен с 14.10 до 15.04, после перезагрузки без изменений

Я использовал Ubuntu 14.10 (Ubuntu MATE), и мой менеджер обновлений обнаружил, что возможно обновление до 15.04. Поэтому я выбрал ОК и обновление началось. Это заняло много времени, но после этого все было закончено, и мне пришлось перезапустить систему.

Но сейчас все то же самое. Там нет изменений. Я проверил ядро ​​с uname -a но это старое ядро ​​14.10 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 также запустил менеджер обновлений sudo apt-get dist-upgrade но нет новых обновлений. Есть что-то подозрительное? Есть идеи?

Изменить: возможно, этот вывод может помочь для анализа:

Я вижу там 3.19 - но почему-то при загрузке моей системы все еще используется 3.16, почему?

lsb_release -c
Codename:   vivid

Почему это ярко, если даже ядро ​​не правильное?

Изменить 4:

Хорошо sudo apt-get install linux-generic действительно решил проблему. После этого я перезагрузился 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 до сих пор не понимаю, почему моя система использовала старое ядро ​​после обновления до 15.04 (может, кто-нибудь может объяснить?), Но я надеюсь, что теперь все в порядке. Спасибо за помощь!

Может быть, просто grub не обновлялся и это была единственная проблема
