While netbooting, in initramfs-tools/scripts/functions, netplan for some reason tries to overwrite /run/net-enp0s3.conf that is initially and correctly generated by ipconfig.
There, it writes unquoted values like the following, which are a shell syntax error:
IPV4DNS0=1.2.3.1 1.2.3.2 1.2.3.3
Then, initramfs-tools/init tries to source that in various places, and produces the following message a lot of times:
/init: /run/net-enp0s3.conf: line 8: 1.2.32: not found
I.e. values should be quoted, and 2 DNS entries should go in IPV4DNS0/IPV4DNS1, not multiple unquoted ones in IPV4DNS0.
Here is the erroneous file that netplan produces:
DEVICE=enp0s3
PROTO=dhcp
IPV4PROTO=dhcp
IPV4ADDR=10.161.254.38
IPV4NETMASK=255.255.255.0
IPV4BROADCAST=10.161.254.255
IPV4GATEWAY=10.161.254.1
IPV4DNS0=194.63.237.4 194.63.239.164 194.63.238.4
ROOTSERVER=10.161.254.1
HOSTNAME=
DNSDOMAIN=
Here is the correct one that ipconfig initially produces, before getting overwritten:
DEVICE='enp0s3'
PROTO='dhcp'
IPV4ADDR='10.161.254.38'
IPV4BROADCAST='10.161.254.255'

Since 18.10, Ubuntu switched to using dhclient instead of ipconfig in initramfs configure_networking(). And now a malformed /run/net-enp0s3.conf is generated, with unquoted values like the following, which are a shell syntax error:
IPV4DNS0=1.2.3.1 1.2.3.2 1.2.3.3
This file is sourced by initramfs-tools/init in various places, and produces the following message a lot of times:
/init: /run/net-enp0s3.conf: line 8: 1.2.3.2: not found
I.e. values should be quoted, and 2 DNS entries should go in IPV4DNS0/IPV4DNS1, not multiple unquoted ones in IPV4DNS0.
Here is the erroneous file that dhclient-enter-hooks.d/config produces:
DEVICE=enp0s3
PROTO=dhcp
IPV4PROTO=dhcp
IPV4ADDR=10.161.254.38
IPV4NETMASK=255.255.255.0
IPV4BROADCAST=10.161.254.255
IPV4GATEWAY=10.161.254.1
IPV4DNS0=194.63.237.4 194.63.239.164 194.63.238.4
ROOTSERVER=10.161.254.1
HOSTNAME=

Here is the correct one that ipconfig produces:
DEVICE='enp0s3'
PROTO='dhcp'
IPV4ADDR='10.161.254.38'
IPV4BROADCAST='10.161.254.255'
IPV4NETMASK='255.255.255.0'

ROOTSERVER='10.161.254.1'
ROOTPATH=''

I.e. please either fix dhclient-enter-hooks.d/config, or revert the ipconfig => dhclient change. |
