Public bug reported:
After:
>apt-get update & apt-get dist-upgrade & reboot
>lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 18.04.1 LTS
Release: 18.04
Codename: bionic
Simple network configuration:
>cat /etc/netplan/network.yaml
network:
version: 2
renderer: networkd
ethernets:
enp0s3:
dhcp4: false
link-local: [ ipv4, ipv6 ]
critical: true
addresses: [ 192.168.10.20/24 ]
gateway4: 192.168.10.254
nameservers:
addresses: [ 8.8.8.8 ]
After system reboot
>ip addr
2: enp0s3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP
group default qlen 1000
link/ether 08:00:27:d0:16:63 brd ff:ff:ff:ff:ff:ff
inet 169.254.123.211/16 brd 169.254.255.255 scope link enp0s3
valid_lft forever preferred_lft forever
inet 192.168.10.20/24 brd 192.168.10.255 scope global enp0s3
valid_lft forever preferred_lft forever
inet6 fe80::a00:27ff:fed0:1663/64 scope link
valid_lft forever preferred_lft forever
looks ok.
route table:
>ip route
default via 192.168.10.254 dev enp0s3 proto static
default dev enp0s3 proto static scope link metric 2048
169.254.0.0/16 dev enp0s3 proto kernel scope link src 169.254.123.211
192.168.10.0/24 dev enp0s3 proto kernel scope link src 192.168.10.20
Don't know what is this second default route for?
After interface flush:
>ip addr flush dev enp0s3
>netplan apply
2: enp0s3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP
group default qlen 1000
link/ether 08:00:27:d0:16:63 brd ff:ff:ff:ff:ff:ff
inet 169.254.123.211/16 brd 169.254.255.255 scope link enp0s3
valid_lft forever preferred_lft forever
inet 192.168.10.20/24 brd 192.168.10.255 scope global enp0s3
valid_lft forever preferred_lft forever
missing ipv6 link-local address (and it's takes few seconds to bring up
ipv4 link-local address up again).
Works after:
ip link set down enp0s3
netplan apply
