Docker构建petereport时遇连接超时与cairocffi安装失败问题

项目地址：https://github.com/1modm/petereport

问题1：添加PPA仓库时连接超时 #

执行Dockerfile第12步时，命令长时间无响应（约2小时），最终抛出连接超时错误，相关命令为：

add-apt-repository ppa:deadsnakes/ppa && apt-get update && apt-get install -y   python3.8   python3-pip   && rm -rf /var/lib/apt/lists/*

报错信息：

注：该命令在宿主机终端中可正常执行

问题2：pipenv安装依赖时cairocffi失败 #

添加-y参数解决上述超时问题后，执行pipenv install --system --deploy --ignore-pipfile步骤时，cairocffi安装失败，报错信息如下：
