php - 无法在 ubuntu 16.10 上再次安装 php5.6-curl。添加了ppa。

Question

我正在尝试安装 php5.6-curl 包。它以前安装过，但我做了一些手动构建 curl 的东西，所以我从系统中删除了 php5.6-curl 包。在此操作之后，我还运行了 apt autoremove。

所以，在成功构建东西之后，我试图调用 apt-get install php5.6-curl 它向我展示了这一点。

dirst@dirst-machine:~$ sudo apt-get install php5.6-curl
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package php5.6-curl is not available, but is referred to by another 
package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'php5.6-curl' has no installation candidate

您可以确定 ppa:ondrej/php5-5.6 已安装在我的 ubuntu 上，因为系统中存在 php5.6 并且之前已安装 php5.6-curl 包。

我还尝试再次添加 ppa 并运行 apt-get update。我不确定这些消息是什么意思。

接下来我尝试检查 apt-cache search php5.6 可用的 php 扩展。没有 php5.6-curl 但我知道它应该在那里。

dirst@dirst-machine:~$ apt-cache search php5.6
php-igbinary - igbinary PHP serializer
php-msgpack - PHP extension for interfacing with MessagePack
php-ssh2 - Bindings for the libssh2 library
php-xdebug - Xdebug Module for PHP

php5.6-mysql - MySQL module for PHP
php5.6-json - JSON module for PHP
php5.6-common - documentation, examples and common module for PHP

php5.6-readline - readline module for PHP
php5.6-gd - GD module for PHP
php5.6-xml - DOM, SimpleXML, WDDX, XML, and XSL module for PHP

php5.6-ldap - LDAP module for PHP
libapache2-mod-php5.6 - server-side, HTML-embedded scripting language (Apache 2 module)
php-memcached - memcached extension module for PHP, uses libmemcached

我还在云中启动了干净的 ubuntu 16.04 并尝试执行相同的操作。
- 安装 php5.6、php5.6-curl。
- 移除 curl 然后手动构建
- 再次安装php5.6-curl

一切都像一个魅力。当我在云 ubuntu 上执行 apt-cache search php5.6 时，扩展列表太大了。

我不知道我做错了什么，我不是很强大的 linux 家伙，所以我不知道发生了什么。请帮忙。

来自 askubuntu 的人提供了帮助。事情很明显。只需将 ppa repo 从 yakkety 更改为 xenial 即可。由于 yakkety 在 repo 中没有 php5.6-curl。
