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

问题描述：

我试图安装php5.6卷曲包。它之前安装过，但是我做了一些手动构建卷曲的东西，所以我从系统中删除了php5.6-curl包。此操作后，我也运行autoremove。无法在ubuntu 16.10上再次安装php5.6-curl。 ppa被添加。

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。

[email protected]:~$ sudo apt-get install php5.6-curl 
Reading package lists... Done 
Building dependency tree

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

你可以肯定的是PPA：的Ondrej/php5-5.6是在我的Ubuntu的安装为php5.6是存在于系统和php5.6卷曲包之前就已isntalled。

我也尝试再次添加ppa并运行apt-get更新。林不知道这个消息是什么意思。

接下来我尝试的是使用apt-cache search php5.6检查php扩展。没有php5.6卷曲，但我知道它应该在那里。

[email protected]:~$ apt-cache search php5.6

我也在云中启动了干净的ubuntu 16.04并试图做同样的动作。 - 安装php5.6，php5.6-curl。 - 删除卷曲，然后手动构建它 - 再次安装php5.6-curl

所有的工作都像一个魅力。当我在云ubuntu上执行apt-cache search php5.6时，扩展名列表太大了。

我不知道我在做什么错，我没有真正强大的Linux家伙，所以我不知道发生了什么事情。请帮忙。

答

askubuntu提供的帮助。事情很明显。只需将ppa repo从yakkety更改为xenial即可使用。由于yakkety在回购时没有php5.6-curl。

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