Debian Jessie UpStart / Systemd / SysV no more reboot

Question

I have make some test on a Jessie server with Upstart installation and replace it by SysV and the reverse.

After this I'm not anymore able to reboot.

root@amoo-001:~# reboot
Failed to talk to init daemon.

root@amoo-001:~# systemctl reboot
Failed to get D-Bus connection: Unknown error -1

Try installing dbus if it complains that dbus is missing – ptman Jul 27 '15 at 13:31 — ptman, Jul 27 '15 at 13:31
@ptman dbus was installed and running. – frbayart Jul 27 '15 at 14:36 — frbayart, Jul 27 '15 at 14:36

I have manually stopped all my important services like LDAP, PostgreSQL and MySQL. And I did run:

reboot -f

The -f force parameter to ignore the init system. After the reboot I was able to make a simple reboot without force mode.

Another solution could be more agressive but useful to know, send a magic sysreq remotely with:

echo b > /proc/sysrq-trigger

See more information about Magic SysReq on Wikipedia.
