无法在 Ubuntu 20.04 焦点上安装 libpcre3-dev

Question

我想

apt install libpcre3-dev

我得到

eading package lists... Done
Building dependency tree
Reading state information... Done
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:
 libpcre3-dev : Depends: libpcre3 (= 2:8.39-12build1) but 2:8.43-1+ubuntu19.10.1+deb.sury.org+1 is to be installed
E: Unable to correct problems, you have held broken packages.

当我尝试安装 libprec3 时：

apt install libpcre3

我得到

Reading package lists... Done
Building dependency tree
Reading state information... Done
libpcre3 is already the newest version (2:8.43-1+ubuntu19.10.1+deb.sury.org+1).

我该如何解决这个问题？注意，我需要安装 libpcre3-dev 因为我想从源代码构建 Nginx，我得到：

./configure: 错误：HTTP 重写模块需要 PCRE 库。您可以使用 --without-http_rewrite_module 选项禁用该模块，或者将 PCRE 库安装到系统中，或者使用 --with-pcre= 选项使用 nginx 从源静态构建 PCRE 库。

根据请求，这里是输出 apt-cache policy libpcre3 libpcre3-dev

您必须安装指定版本的软件包：

sudo apt-get install libpcre3=2:8.39-12build1 libpcre3-dev=2:8.39-12build1

发生这种情况的原因如下：前段时间您libpcre3已从 PPA安装，但现在已删除或禁用 PPA。
