操作系统为Ubuntu14.04
在Openstack软件包安装过程中，主机的DNS没问题，软件源的仓库也是正确的，为什么总是出现软件包安装错误呢？
报错如下：
# apt-get install cinder-api cinder-scheduler cinder-volume python-cinderclient -y

cinder-api is already the newest version.

屏幕上的报错，一下跳到最后，怎么检查都没查出来。
于是回头分析报错的根源：
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = "en_US:en",
LC_ALL = (unset),
LC_CTYPE = "UTF-8",
LANG = "en_US.UTF-8"
are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory
这几个警告是提示系统环境的locale设置，太常见很容易忽略。

但这部分已经说软件包由于系统环境的编码格式导致错误。
如果不处理，那在apt安装其他软件时还会报相同的错。
很多时候，我们会把这部分与上面的警告混在一起，从而转移注意力到其他地方。
解决方法为：
echo ‘LC_ALL="en_US.UTF-8"‘ >> /etc/default/locale
注：此环境的OS为ubuntu14.04。其他OS根据实际环境设置。
退出当前终端，重新登录，查看当前终端环境的locale：
# locale
LANG=en_US.UTF-8
LANGUAGE=en_US:en
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=en_US.UTF-8
再次使用apt-get安装即可成功。
