删除php 5.6.23-1已弃用dontuse deb.sury.org~trusty 1

我用Nginx在ubuntu 14.04上安装了PHP,但安装的版本是PHP 5.5.9.因为我想将它升级到PHP 5.6,所以我解雇了以下命令：

sudo apt-get install software-properties-common
sudo add-apt-repository ppa:ondrej/PHP5-5.6
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install PHP5

我收到一条消息,指出ppa已被删除,但是PHP 5.6已经安装并正常工作只是它显示为PHP 5.6.23-1已弃用dontuse deb.sury.org~trusty 1(cli)我后来继续进入命令LC_ALL = C.UTF-8 add-apt-repository ppa：ondrej / PHP和sudo apt-get install PHP5.6再次为我安装了PHP5.6.

现在当我这样做：PHP -v我得到PHP 5.6.23-1 deb.sury.org~trusty 2(cli)当我这样做：PHP5 -v我得到PHP 5.6.23-1不推荐使用dontuse deb.sury.org ~trusty 1(cli)如何删除已弃用的？

# Remove old ppa: and its packages

sudo apt-get --purge remove PHP5-common
# Add the new ppa:
sudo add-apt-repository ppa:ondrej/PHP
sudo apt-get update
# If you are using it with Apache,run:
