从 PPA 安装 PHP5.6 时 Ubuntu 中的 UnicodeDecodeError

Question

我有一个干净的 VPS，使用 Ubuntu 14.04 LTS x64。并尝试了以下操作：

# Upgrade The Base Packages

apt-get update
apt-get upgrade -y

# Add A Few PPAs To Stay Current

apt-get install -y software-properties-common

apt-add-repository ppa:nginx/stable -y
apt-add-repository ppa:rwky/redis -y
apt-add-repository ppa:chris-lea/node.js -y
apt-add-repository ppa:ondrej/php5-5.6 -y

但是在最后一个失败了：

root@xxx:~# apt-add-repository ppa:ondrej/php5-5.6 -y

    return codecs.ascii_decode(input, self.errors)[0]

我想不通出了什么问题。这一切都很基本。

Answer 1

正确的方法是在终端中启用 UTF-8 支持。

首先检查您的语言环境：

locale -a

然后，安装一个 UTF-8 语言环境，为 en_US，示例如下：

locale-gen en_US.UTF-8

然后你需要导出它：

export LANG=en_US.UTF-8

然后add-apt-repository命令将正常工作。

如果这仍然不起作用，请尝试使用以下行：

LC_ALL=en_US.UTF-8 add-apt-repository -y ppa:ondrej/php

Answer 2

请尝试以下操作：

• 如果您已经安装了 php5，请删除。

• 现在尝试全新安装。

• 运行gedit /etc/apt/sources.list添加以下代码：

  deb http://ppa.launchpad.net/ondrej/php5-5.6/ubuntu trusty main 
  deb-src http://ppa.launchpad.net/ondrej/php5-5.6/ubuntu trusty main
  

  ^{请小心编辑和添加源代码。}

• 保存并更新它。(1234)

  sudo apt-get update  
  

• 现在尝试安装php5。

安装后你应该得到 php5-5.6。
