ubuntu 14.04 刪除ibus輸入法引發的問題及解決方法

      刪除自帶的ibus輸入法，導致系統設置及其他一些東西沒法使用。

解決方法：

sudo apt-get install ubuntu-desktop

sudo reboot

安裝之前可能需要更換一個速度快的軟件源，本來可以在系統設置裏設置，但是現在系統設置打不開了，所以只能在終端裏配置了。

cd /etc/apt/

sudo cp sources.list sources.list.bak

sudo gedit sources.list

清空內容，加入如下內容：

deb http://mirrors.163.com/ubuntu/ trusty main restricted universe multiverse

deb http://mirrors.163.com/ubuntu/ trusty-security main restricted universe multiverse

deb http://mirrors.163.com/ubuntu/ trusty-updates main restricted universe multiverse

deb http://mirrors.163.com/ubuntu/ trusty-proposed main restricted universe multiverse

deb http://mirrors.163.com/ubuntu/ trusty-backports main restricted universe multiverse

deb-src http://mirrors.163.com/ubuntu/ trusty main restricted universe multiverse

deb-src http://mirrors.163.com/ubuntu/ trusty-security main restricted universe multiverse

deb-src http://mirrors.163.com/ubuntu/ trusty-updates main restricted universe multiverse

deb-src http://mirrors.163.com/ubuntu/ trusty-proposed main restricted universe multiverse

deb-src http://mirrors.163.com/ubuntu/ trusty-backports main restricted universe multiverse

然後更新軟件列表：

sudo apt-get update
