SystemD：软件包systemd-sysv不可用，但由另一个软件包引用

Question

I am trying to install and configure systemD on lindux debian but I get errors when installing systemd-sysv which I understood was necessary to get systemD to manage services.

When I run

apt-get install systemd-sysv

I get :

# apt-get install systemd-sysv
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package systemd-sysv 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 'systemd-sysv' has no installation candidate

Does someone know how to overcome this ? How can I have a running version of systemD on my system?

Answer 1

ubuntu started shipping systemd with Utopic Unicorn (where it is in the universe repository) and fully includes it since (the currently upcoming) Vivid Vervet .

Therefore, if you want to install systemd on your ubuntu-system (via the package manager), you need to first upgrade your entire system to a version that actually supports it.
