如何Ubuntu Software Center在 Ubuntu Gnome 17.04 上安装 Zasty Zepus (笔记：不同于Ubuntu Software）？
我们知道，Ubuntu GNOME 默认GNOME Software自带。但是，我需要旧版本，Ubuntu Software Center因为那里可以找到一些软件包。我已经尝试搜索Synaptic Package Manager，但没有成功。我还尝试运行sudo apt-get install software-center，但结果如下：
Package software-center is not available, but is referred to by
another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'software-center' has no installation candidate
我特别寻找的是GStreamer plugins for mms, wavpack, quicktime, musepack (thorugh Ubuntu Software Center)。
谢谢！

“software-center”：新的软件包名称是gnome-software http://packages.ubuntu.com/search?suite=default§ion=all&arch=any&keywords=software&searchon=names
旧软件中心http://old-releases.ubuntu.com/ubuntu/pool/main/s/software-center/... 源包，版本 software-center_1.0.2.tar.gz ... 至 software-center_13.10.orig.tar.gz ( 最新版本的补丁：software-center_13.10-0ubuntu4.1.debian.tar.gz )
