locale问题:Cannot set LC_CTYPE to default locale

刚购买的VPS默认安装的系统是CentOS,没想到CentOS现在这么火,很多VPS默认安装这个。但是我只用Debian或FreeBSD,重新安装了一下Debian lenny AMD64,几分钟就完成了。sudo apt-get upgrade时出现错误提示:

locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory

原来是默认没有设置locale
用这个命令dpkg-reconfigure locales配置一下,选个lcoale就好了,我用en_US.UTF-8。
