由于未满足的依赖性，无法在Ubuntu 18上安装PHP7.2-dev

Question

我有Ubuntu 18分配，但我需要安装php7.2-dev用于PECL扩展。

mvolchkov@ias-su:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 18.04 LTS
Release:    18.04
Codename:   bionic

我尝试安装php7.2-dev：

mvolchkov@ias-su:~$ sudo apt-get install php7.2-dev
Unresolved packages:
 php7.2-dev : Depend on: libpcre3-dev (>= 2:8.35) but will not be installed
              Depend on: libssl-dev but will not be installed

但它取决于：libpcre3-dev 比我尝试安装libpcre3-dev，但得到以下错误：

mvolchkov@ias-su:~$ sudo apt-get install libpcre3-dev
 libpcre3-dev : Depend on: libpcre3 (= 2:8.39-9) но 2:8.41-4+ubuntu17.10.1+deb.sury.org+1 will be installed
E: Impossible to resolve problems, you have held packages.

Answer 1

我经历了同样的问题来解决这个问题：

sudo add-apt-repository ppa: ondrej/php -y
sudo apt-get update
sudo apt-get install php7.2-dev

如果它不起作用尝试强制它像这样：这个解决方案太过分了，因为你将强制安装未经身份验证的数据包

sudo apt-get install php7.2-dev  -y --all-not authenticated
