Ubuntu 启动菜单有乱码

启动后发现启动菜单有乱码，按e进去又改不了，

只好去改写/boot/grub/grub.cfg文件，记得以前是menu.lst，名字改来改去真是烦

 

后来启动或使用apt-get时老出现

 

 

 

perl: warning: Setting locale failed.

perl: warning: Please check that your locale settings:

LANGUAGE = (unset),

LC_ALL = (unset),

LANG = "en_US.UTF-8"

    are supported and installed on your system.

perl: warning: Falling back to the standard locale ("C").

去改文件 /etc/default/locale:

LC_ALL = "C"
