本文记录我在 Debian 安装 dotnet 失败，报错信息是 packages-microsoft-prod depends on ca-certificates; however: Package ca-certificates is not installed.
一开始按照官方的以下代码例子进行安装 packages-microsoft-prod.deb 文件，命令如下
sudo dpkg -i packages-microsoft-prod.deb
报错信息如下
(Reading database ... 9939 files and directories currently installed.)

dpkg: dependency problems prevent configuration of packages-microsoft-prod:
packages-microsoft-prod depends on ca-certificates; however:
Package ca-certificates is not installed.
根据网上提供的命令，通过以下命令重新安装 ca-certificates 工具
sudo apt-get install --reinstall ca-certificates
依然提示失败，这次是依赖的 openssl 没有安装，错误提示如下
Reading package lists... Done
Building dependency tree... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
ca-certificates : Depends: openssl (>= 1.1.1) but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution)
解决方法：
先通过 apt --fix-broken install 命令解开错误，输入命令行如下
sudo apt --fix-broken install
运行成功，输出如下
