问题描述
我在 GitHub Actions 上的 Ubuntu 16.04 上安装 libzmq3-dev 时遇到问题。 这可能是我的用户错误，因为我在本地 Ubuntu 机器上安装它时没有遇到错误。我很感激故障排除建议，例如我应该在 libzmq3-dev 之前专门在 GHA 机器上安装库。
我向 https://github.com/wlandau/libzmq-reprex/runs/2521101152 发布了一个最小的可重现示例。 相关：Cannot install libzmq3-dev on ubuntu 19.04。
Run sudo apt-get install libzmq3-dev

解决方法
我在 Azure Pipelines 中遇到了同样的问题。我的解决方法是从 OpenSUSE repository 安装 libzmq3-dev。
