Installiere systemd-sysv
:
apt install systemd-sysv
Erläuterung
Failed to get D-Bus connection: Unknown error -1
bedeutet, dass systemd nicht läuft.
Hier ist meine LMDE 2-Installation, die Debian 8 sehr ähnlich ist:
lmde ~ # systemctl status ssh.service Failed to get D-Bus connection: Unknown error -1
Auf Ihrem System ist /sbin/init
wahrscheinlich kein Symlink, der auf zeigt /lib/systemd/systemd
. So sieht es auf LMDE 2 aus:
lmde ~ # file /sbin/init /sbin/init: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=416c01d5df07b3a795694ff3360339b509daaf86, stripped
So sieht es auf Ubuntu 16.04 LTS aus, auf dem standardmäßig systemd ausgeführt wird:
root@node51 [~]# file /sbin/init /sbin/init: symbolic link to /lib/systemd/systemd
Um dies zu beheben, ersetzen Sie das Paket sysvinit-core
durchsystemd-sysv
:

Starten Sie jetzt mit reboot
.
Nach dem Neustart des Systems führen Sie systemd anstelle von SysV aus:

Mögliche Ursache?
Sie haben angegeben, dass systemd in Ihrer Debian-Installation in der Vergangenheit funktioniert hat. Es ist möglich, dass ein Paket oder seine Abhängigkeiten SysVinit anstelle von systemd und gelöschtes oder deaktiviertes systemd erfordern.
Seien Sie auf der Suche nach gebrochenen Abhängigkeiten, wenn dies der Fall ist.

lmde ~ # apt show systemd-sysv Package: systemd-sysv State: installed Automatically installed: no Version: 215+12+betsy Priority: extra Section: admin Maintainer: Debian systemd Maintainers <pkg-systemd-maintainers@lists.alioth.debian.org> Architecture: amd64 Uncompressed Size: 77.8 k Depends: systemd (= 215+12+betsy) PreDepends: systemd Conflicts: sysvinit-core, sysvinit-core, upstart, upstart, systemd-sysv Replaces: sysvinit (< 2.88dsf-44~), sysvinit (< 2.88dsf-44~), sysvinit-core, sysvinit-core, upstart, upstart Description: system and service manager - SysV links systemd is a replacement for sysvinit. It is dependency-based and able to read the LSB init script headers in addition to parsing rcN.d links as hints. It also provides process supervision using cgroups and the ability to not only depend on other init script being started, but also availability of a given mount point or dbus service. This package provides the manual pages and links needed for systemd to replace sysvinit. Installing systemd-sysv will overwrite /sbin/init with a link to systemd.
