Public bug reported:
I use Ubuntu 17.10 Server 64bit with latest updates. (Fresh
installation)
apt-cache policy netplan
netplan:
Installed: (none)
Candidate: 1.10.1-5
Version table:
1.10.1-5 500
500 http://at.archive.ubuntu.com/ubuntu artful/universe amd64 Packages
apt-cache policy ifupdown
ifupdown:
Installed: 0.8.16ubuntu2
Candidate: 0.8.16ubuntu2
Version table:
*** 0.8.16ubuntu2 500
500 http://at.archive.ubuntu.com/ubuntu artful/main amd64 Packages
100 /var/lib/dpkg/status
systemd-networkd is installed and used
Network-Manager is not installed.
/etc/network/interfaces is untouched after installation
Netplan does not set device name configured in /etc/netplan/01-netcfg.yaml
Here my .yaml
network:
version: 2
renderer: networkd
ethernets:
lan:
match:
macaddress: 00:12:34:56:29:e8
set-name: lan
dhcp4: false
dhcp6: false
accept-ra: false
addresses:
- 10.10.0.48/24
- 1701:5740:5000:3301::48/64
I had to switch back to predictable device names like "eth0" in /etc/default/grub with
GRUB_CMDLINE_LINUX_DEFAULT="net.ifnames=0 biosdevname=0" and update-grub.
After this change and reboot, the name is set properly but the network remains still unconfigured.
You have to login with console and type 'netplan apply' or 'systemctl restart systemd-networkd'.
This command will configure the network.
Funny thing about this behavior. If you reboot the system more often,
out of 10 times one time network gets configured properly. I guess this
is a timing issue.
'systemd-analize blame' shows what services are started at what time. I found out this difference.
With unconfigured network systemd-networkd is started at about 34ms
With configured network systemd-networkd is usually started at about 400ms
I played around a lot with timing in systemd-network.service but that
did not change the thing.
