Public bug reported:
In bionic, running systemd 237-3ubuntu10.22 and netplan.io
0.97-0ubuntu1~18.04.1, systemd-networkd fails to configure an interface
with a static IPv4 address if the statically confiugred address is the
same as the interface already has gotten from DHCP.
This will cause the interface to loose its IP address when the DHCP
lease exires, even though you've told netplan to configure it as static.
I expect systemd-networkd to actually configure an IP address as static,
regardless of what address the interface has before from DHCP.
# lsb_release -rd
Description: Ubuntu 18.04.2 LTS
Release: 18.04
# apt-cache policy systemd
systemd:
Installed: 237-3ubuntu10.22
# apt-cache policy netplan.io
netplan.io:
Installed: 0.97-0ubuntu1~18.04.1
A paste of systemd-networkd's debug log when I run "netplan apply" and
the interface already has the static IP configured from DHCP.
It seems like upon a restart, systemd-networkd will allways add whatever
IP config it had before the service stopped, and then apply changes (if
any). Since my new config has the same IP as it already had, it does
nothing even though the new config has static configuration.
