我正在基于如何安装 unrar-nonfree? 在 Raspbian 上安装 unrar-nonfree？(raspberrypi.stackexchange.com)但使用 Ansible。我使用 ansibles: apt_repository 成功添加了 apt 存储库，它会在发生更改时更新缓存（默认）。在我尝试运行之后立即：
sudo apt-get build-dep unrar-nonfree
但是使用 ansible 的等价物：
- apt:
pkg: unrar-nonfree
state: build-dep
除非这失败了：fatal: [192.168.2.3]: FAILED! => {"changed": false, "failed": true, "msg": "No package matching 'unrar-nonfree' is available"}
失败的扩展 (-vvv) 日志：
