Sto seguendo questo tutorial per installare Linux in un sistema che non dispone di lettore CD né funzionalità di avvio USB. Alla fine, ho raggiunto il punto in cui dovevo installare isc-dhcp-server
e l'ho fatto, in un certo senso .
Apt
mi dice che esiste un pacchetto parzialmente installato. Corro sudo apt-get install -f
e ottengo quanto segue:
Job for isc-dhcp-server.service failed. See 'systemctl status isc-dhcp server.service' and 'journalctl -xn' for details.
invoke-rc.d: initscript isc-dhcp-server, action "start" failed.
dpkg: error processing package isc-dhcp-server (--configure):
subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
isc-dhcp-server
E: Sub-process /usr/bin/dpkg returned an error code (1)
Se lo faccio, /etc/init.d/isc-dhcp-server start
il prompt è costituito dalle prime due righe dello stesso messaggio.

Devo nascondere il mio indirizzo IP?
dhcpd
sta iniziando e qui stiamo arrivando solo alla fine dei suoi messaggi. Sembra che si stia lamentando della dhcpd.conf
mancanza di alcune informazioni richieste. È necessario tornare un po 'più indietro nei registri di sistema, per vedere l'intera serie di messaggi da dhcpd
. Su un sistema tradizionale in cui dovrebbero trovarsi i log /var/log/syslog
, non so se systemd rovini tutto.
