Debian 8 - 安装 php7.0 的设置首选项

  • 772

请帮助设置安装 php7.0 和相关软件包的首选项（其中一些不是稳定版本）。

我有操作系统 Debian 8。

我在以下位置设置包的源列表etc\apt\sources.list.d\：

security.list

deb http://security.debian.org/ stable/updates  main contrib non-free
deb http://security.debian.org/ testing/updates main contrib non-free

stable.list

deb     http://ftp.de.debian.org/debian/ stable main contrib non-free
deb-src http://ftp.de.debian.org/debian/ stable main contrib non-free

testing.list

deb     http://ftp.de.debian.org/debian/ testing main contrib non-free
deb-src http://ftp.de.debian.org/debian/ testing main contrib non-free

unstable.list

deb     http://ftp.de.debian.org/debian/ unstable main contrib non-free
deb-src http://ftp.de.debian.org/debian/ unstable main contrib non-free

我在以下位置为包设置了一些首选项文件etc\apt\preferences.d\：

security.pref

Package: *
Pin: release l=Debian-Security
Pin-Priority: 1000

stable.pref

Package: *
Pin: release a=stable
Pin-Priority: 900

testing.pref

Package: *
Pin: release a=testing
Pin-Priority: 750

unstable.pref

Package: *
Pin: release a=unstable
Pin-Priority: 50

我创建99default-release了etc\apt\apt.conf.d\包含内容的文件：

APT::Default-Release "stable";

最后，当我运行安装 php7.0 的命令时，出现下一个错误：

root@machie:/etc# apt-get install php7.0

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 php7.0 : Depends: libapache2-mod-php7.0 but it is not going to be installed or
                   php7.0-fpm but it is not going to be installed or
                   php7.0-cgi but it is not going to be installed
W: No priority (or zero) specified for pin
E: Unable to correct problems, you have held broken packages.

PS 没有来源、首选项和 apt.conf 文件 php7.0 安装成功表单“ deb http://packages.dotdeb.org jessie all” repo。但我希望这是可能的设置偏好。

linux apt preferences php7 debian-jessie

    http://packages.dotdeb.org我只是从sources.list 中删除repo。现在我可以通过执行命令从 debian repo 安装测试版本：

    sudo apt-get install -f -y -t testing php7.0 php7.0-curl php7.0-cli php7.0-gd php7.0-xml php7.0-mbstring php-xdebug

    完全依赖（apache2等）

    对于更新测试包运行命令：

    apt-get install `apt-show-versions -u -b | grep testing`

    要将任何软件包降级到稳定版本，请etc\apt\preferences.d\使用以下内容创建文件：

    Package: <package_name_here> 
Pin: release a=testing
Priority: 1001

    并运行apt-get update
