The following tutorial describes how to emergency shutdown Debian when it does not respond to shutdown -r now.
When we issue the command

shutdown -r now 

and we get the result:

Failed to start reboot.target: Activation of org.freedesktop.systemd1 timed out
Failed to open initctl FIFO: Nie ma takiego urządzenia ani adresu
Failed to talk to init daemon.

The way to force a safe shutdown would be:

emergency shutdown:

echo 1 > /proc/sys/kernel/sysrq

echo o > /proc/sysrq-trigger

emergency restart:

echo 1 > /proc/sys/kernel/sysrq

echo b > /proc/sysrq-trigger
