Tdenham Tengo la misma situación Acabo de actualizar el sistema de 14.04 a 16.04 con do-release-upgrade -d
.
Si no tiene acceso directo al sistema y realmente necesita reiniciar, puede intentar restablecer el hardware como una solución alternativa (como se describe aquí: https://major.io/2009/01/29/linux-emergency- reiniciar-o-apagar-con-comandos-mágicos / )
echo 1 > /proc/sys/kernel/sysrq
echo b > /proc/sysrq-trigger
que hace el truco. Probablemente deberías correr sync
justo antes del segundo comando.
reboot -f
puede ayudar, pero no lo intenté ya que no puedo acceder al servidor si se cuelga nuevamente.
Puede consultar el archivo / var / log / syslog. Encuentre el lugar donde enciende la computadora y verifique las líneas justo antes de eso. Puedes pegarlo aquí.

Parece que dhclient intenta alcanzar la dirección IP incluso cuando se solicita el reinicio.
En caso de que sea un problema dependiente del hardware, pegué la salida lspci
para ayudar a solucionarlo.
