从14.04升级到14.10, 为什么kernel版本还是3.13？？？

[dp9463]

升级过程中没有报错，升级之后重启了操作系统，发现ｋｅｒｎｅｌ版本还是３．１３：
shawn@dengpeng:~$ uname -a
Linux dengpeng 3.13.0-38-generic #65-Ubuntu SMP Thu Oct 9 11:39:01 UTC 2014 i686 i686 i686 GNU/Linux

查看操作系统版本，发现已经是１４．１０了．
shawn@dengpeng:~$ cat /etc/lsb-release

DISTRIB_RELEASE=14.10
DISTRIB_CODENAME=utopic

應該沒錯

可能原因
你有使用 proxy
把 proxy 關閉看看

如果還是無效
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo reboot
看看

如果還是無效
可能原因
下載伺服器跟不上更新套件
多更新幾天看看

如果還是無效
更換一下 下載伺服器看看

如果還是無效
把下述指令複製貼上終端機執行
sudo dpkg -l | grep linux-generic
sudo dpkg -l | grep linux-headers-generic
sudo dpkg -l | grep linux-image-generic
