php - 在 Ubuntu 16 上安装 PHP 7

Question

我尝试在我的 Ubuntu 16 中将 PHP 版本设置为 7，但安装以错误结束:

Setting up install-info (6.1.0.dfsg.1-5) ...
/usr/sbin/update-info-dir: 3: /etc/environment: Syntax error: Unterminated quoted string
dpkg: error processing package install-info (--configure):
 subprocess installed post-installation script returned error exit status 2
Errors were encountered while processing:
 install-info
E: Sub-process /usr/bin/dpkg returned an error code (1)

运行 php -v php 版本保持不变:

mycomputer@mycomputer:~$ php -v

PHP 5.6.11-1ubuntu3.4 (cli) 
Copyright (c) 1997-2015 The PHP Group
Zend Engine v2.6.0, Copyright (c) 1998-2015 Zend Technologies
    with Zend OPcache v7.0.6-dev, Copyright (c) 1999-2015, by Zend Technologies

我遵循此链接中的这些说明:

https://tecadmin.net/install-php-7-on-ubuntu/

哪个是:

sudo apt-get install python-software-properties
sudo add-apt-repository ppa:ondrej/php
sudo apt-get update
sudo apt-get install -yphp7.0

如何修复错误并修复它以在我的 Ubuntu 16 上安装 PHP 7？

命令行告诉您在哪里查看:

/usr/sbin/update-info-dir: 3: /etc/environment: Syntax error: Unterminated quoted string

你能检查一下你的 /etc/environment上是否有错误吗？文件？
