安装 nodejs-dev 失败（取决于 libssl1.0-dev）但我已经安装了 libssl-dev

Question

$ sudo apt-get install nodejs-dev
[...]
The following packages have unmet dependencies:
 nodejs-dev : Depends: libssl1.0-dev (>= 1.0.2) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

然后检查我已经安装的软件包的版本libssl-dev：

$ dpkg -L libssl-dev | grep libssl.pc
/usr/lib/x86_64-linux-gnu/pkgconfig/libssl.pc
$ grep Version /usr/lib/x86_64-linux-gnu/pkgconfig/libssl.pc
Version: 1.1.1

然后检查将从包安装的版本libssl1.0-dev：

$ apt-get download libssl1.0-dev
$ ar x libssl1.0-dev_1.0.2n-1ubuntu6.2_amd64.deb
$ tar xf data.tar.xz
$ grep Version usr/lib/x86_64-linux-gnu/pkgconfig/libssl.pc 
Version: 1.0.2n

为什么当我已经有1.1.1 版本并且依赖低于该版本的版本时apt-get拒绝安装，即版本 >= 1.0.2？nodejs-devlibsslnodejs-dev

然后
