How do you fix a "failed to start dhcpcd on all interfaces" error?

Question

i've never had this error since i bought my rpi3 last january. Any advice?

Details:

OS: Raspbian Stretch

Never edited /etc/network/interfaces as pi is attached to router via cable and had not needed to use wi-fi

journalctl -e (errors found)

vc_vhci_sm_init: failed to open VCHI service (-1)

What OS + version do you run? Did you modify /etc/network/interfaces? Please add that information to your question. — Dirk, Aug 08 '18 at 07:28
Currently version is stretch and no modifications made to interfaces. Just used network cable to router from the beginning and thats it. This just happened today so I'm very confused. — Kurover, Aug 08 '18 at 07:35
Please edit your question and add the output from ip addr. That will give an overview about the status of your interfaces. Look at journalctl -e for any error messages. — Ingo, Aug 08 '18 at 07:43
Updated with results from ip addr and errors from journalctl -e — Kurover, Aug 08 '18 at 08:17
Odd error starting dhcpcd5 (Exec format error). What does 'file' report on that file (should be a script)? Also 'file /sbin/dhcpcd' — Dirk, Aug 08 '18 at 08:34
@Kurover: Before you reformat, please run this, and report result journalctl -u dhcpcd.service — Seamus, Aug 08 '18 at 13:41
Also: This is worth asking Roy Marples a question... but I think his mail list server is having issues at the moment, so you may need to wait a bit. — Seamus, Aug 08 '18 at 13:46

For those googlin' "failed to start dhcpcd on all interfaces" like myself:

NB: This is relevant to Raspbian Stretch; for a different release, the situation may differ.

Essentially, if your Pi has a wired DHCP connection, and you have eth0 in /etc/network/interfaces -- something like that :

# .. loopback interface ..
auto eth0
iface eth0 inet dhcp

Then it shall be enough and you can now disable dhcpcd.service :

systemctl disable dhcpcd

This shall be it -- reboot ( and don't forget to start your DCHP server, if your client is dhcp-bound ) and you shall not have this message for anymore.

Explanation: I suppose we have triggered dhcpcd.service into an enabled state, and since its Description field is "dhcpcd on all interfaces" -- it goes into the log file as "failed to start dhcpcd on all interfaces" . That's it.

Edit: fixed typos, thanks Ingo

Seems you have done some typos. There is no dhcpd service you can disable. Do you mean dhcpcd? – Ingo Jan 20 '19 at 13:57
@Ingo : thanks, it did not occur to me it has a 'c' there. I mean, I did it just not too long ago, but nevertheless did some typing mistakes here. Thanks again ) – ジョージ Jan 20 '19 at 14:58

Of course -- my bad. It is a client, therefore it shall go with a 'c'. – ジョージ Jan 20 '19 at 15:00
