尝试使用 Launchpad 配方打包源文件时出现以下错误。但是，我可以在我的机器中成功构建包（运行 18.04）
dh: error: unable to load addon python3: Can't locate Debian/Debhelper/Sequence/python3.pm
这是完整的buildlog，我的debian/control文件如下。

Description: A beautiful Clock, inspired by Ubuntu Touch homescreen, already on your desktop.
Inspired by Ubuntu Touch homescreen, this clock is able to show you the
time in a way you never seen before. The "clouds" changes colors and
sizes automaticaly awhile showing you the time.
如何解决这个问题？我已经添加python3-distutils-extra到Build-Depends.
在文件中添加
dh-python到 Build-Depends 。debian/control完成此操作后，Launchpad 构建不会引发任何错误。
