Ubuntu Xenial 官方 Ubuntu 存储库python3-pychromecast中不存在源包。
我想下载Ubuntu Bionic python3-pychromecast源包并在 Ubuntu Xenial 上重建它：
$ sudo apt-get build-dep python3-pychromecast/bionic-universe
Reading package lists... Done
E: Unable to find a source package for python3-pychromecast/bionic-universe
$ apt-get source --compile python3-pychromecast/bionic-universe
Reading package lists... Done
E: Unable to find a source package for python3-pychromecast
EDIT0：下载并提取源包：
