我试图在Ubunt 12.04上将php 5.3升级到5.6，但在尝试安装任何内容时遇到错误：
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:

are supported and installed on your system.

当我试图添加这个剧目时：
sudo add-apt-repository ppa:ondrej/php5.6
我收到了以下错误：
Cannot access PPA
(https://launchpad.net/api/1.0/~ondrej/+archive/php5.6) to get PPA
information, please check your internet connection.
请帮忙吗？
