Question

简单的问题。

我正在尝试在ubuntu上安装php + memcached。

首先，我这样做：

$ sudo add-apt-repository ppa:ondrej/php5-5.6 # Good
$ sudo apt-get update                         # Good
$ sudo apt-get upgrade -y                     # Good
$ sudo apt-get install php5 -y                # Good
$ sudo apt-get install php5-fpm -y            # Good

但是：

$ sudo apt-get install php5-memcached -y

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 php5-memcached : Depends: php5-common (= 5.3.29-1~dotdeb.0) but 5.6.9+dfsg-1+deb.sury.org~precise+2 is to be installed
E: Unable to correct problems, you have held broken packages.

有关服务器的一些信息：

$ cat /etc/*-release | grep PRETTY
PRETTY_NAME="Ubuntu precise (12.04.5 LTS)"

$ php -v | grep PHP
PHP 5.6.9-1+deb.sury.org~precise+2 (cli) (built: May 26 2015 15:13:29)

$ php5-fpm -v | grep PHP
PHP 5.6.9-1+deb.sury.org~precise+2 (fpm-fcgi) (built: May 26 2015 15:38:14)

$ apt-cache policy php5-common
php5-common:
  Installed: 5.6.9+dfsg-1+deb.sury.org~precise+2

如何解决此问题并在5.6上安装memcached扩展？

我也尝试从PECL安装，但是

$ pecl install memcache
pecl/memcache is already installed and is the same as the released version 2.2.7
install failed

谢谢！

我已经用OndřejSurýrepo和aptitude解决了这个问题。我有PHP 5.5.9（Ubuntu 14.04）。这是消息

以下软件包具有未满足的依赖项： php5-memcached：取决于：php5-common（= 5.3.29-1~dotdeb.0）但是要安装5.5.9 + dfsg-1ubuntu4.9

我添加了Ondrej repo：

sudo add-apt-repository ppa:ondrej/php5
sudo apt-get update

然后安装php5-memcache和php5-memcached：

sudo aptitude install php5-memcached

并按“n”几次，当aptitude提供旧的PHP版本。经过约5次才得以说：

Next actions will solved depends:

 Install next packets:             
1)     php5-memcached [2.1.0-6build1 (trusty)]
Accept this solution? [Y/n/q/?]

按Y.

Ubuntu 12.04 + PHP 5.6 + Memcached =如何解决依赖关系？
