I need to install
libcgmanager0 for some other package, however
sudo apt install install libcgmanager0 returns:
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
This site https://packages.ubuntu.com/xenial/libcgmanager0 also shows an error and I just don't know what to do.
Is there any other source I can get it from or how do I solve this problem?
