我需要安装libcgmanager0一些其他包，但是sudo apt install install libcgmanager0返回：
Package libcgmanager0 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 'libcgmanager0' has no installation candidate
本网站https://packages.ubuntu.com/xenial/libcgmanager0也显示错误，我不知道该怎么办。
我可以从其他来源获得它吗？或者我该如何解决这个问题？
