IPv4 is not showing, current Ubuntu build says "Failed to start Raise network interfaces"
Hi, I have a droplet with IPv4 and IPv6 enabled. It has never been a problem. However, yesterday I somehow managed to break my droplet while upgrading. IPv6 looks fine but IPv4 is now missing from my IP if I run
$ip addr .
I can access the DO console to test, but cannot ssh in or ping from my terminal.
$cat /etc/network/interfaces.d/* looks the same as an older snapshot (too old unfortunately). Changing network interfaces has yet to produce anything encouraging. My firewall is disabled. Not sure where else to look.
$sudo reboot shows the error:
"Failed to start Raise network interfaces".
DO support has responded and recommended the following:
$ ip addr learned that inet6 displays, inet not present
$ ip route no change
$ ls -l /lib/modules total 8 drwxr-xr-x 5 root root 4096 Jun 13 07:00 4.4.0-128-generic drwxr-xr-x 5 root root 4096 Jul 2 13:51 4.4.0-130-generic
$iptables -nvL --line-numbers empty
and lastly removing
/etc/udev/rules.d/70-persistent-net.rules results in no change.
As per support I learned that IPv4 is not present. Support suggested "ensuring IPv4 is present" although I'm not sure how to go about accomplishing that.
Hopefully someone out here can throw me a bone, it has been a long night.
