在 Ubuntu 中安装 libssl-dev 和 libssl1.0-dev 时出错

Question

我正在尝试通过以下命令在 Ubuntu 18.04 中安装 libssl-dev 和 libssl1.0-dev：

sudo apt-get -y install build-essential openssl libssl-dev libssl1.0 libgl1-mesa-dev libqt5x11extras5

我得到以下输出：

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Note, selecting 'libssl1.0-dev' for regex 'libssl1.0'
Note, selecting 'libssl1.0.0' for regex 'libssl1.0'
Note, selecting 'libssl1.0.2' for regex 'libssl1.0'
build-essential is already the newest version (12.4ubuntu1).
libqt5x11extras5 is already the newest version (5.9.5-0ubuntu1).
libqt5x11extras5 set to manually installed.
libgl1-mesa-dev is already the newest version (20.0.8-0ubuntu1~18.04.1).
libgl1-mesa-dev set to manually installed.
libssl-dev is already the newest version (1.1.1-1ubuntu2.1~18.04.20).
libssl1.0.0 is already the newest version (1.0.2n-1ubuntu5.10).
openssl is already the newest version (1.1.1-1ubuntu2.1~18.04.20).
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:
 libssl-dev : Conflicts: libssl1.0-dev but 1.0.2n-1ubuntu5.10 is to be installed
 libssl1.0-dev : Conflicts: libssl-dev but 1.1.1-1ubuntu2.1~18.04.20 is to be installed
E: Unable to correct problems, you have held broken packages.**

以下命令序列应该可以解决依赖关系。

$ sudo apt-get install -f # 修复系统上损坏的依赖项。

$ sudo dpkg -–configure -a # 重新配置所有解压的包。

$ sudo apt-get install -f # 修复系统中损坏的依赖项。

$ sudo apt-get install <package_name> # 在系统上安装包。
