Ubuntu: netplan disable dhcp

system ip configuration b4 netplan edit:

root@pro-rpi-02:/# ip a sh
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether dc:a6:32:b3:45:e0 brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.2/26 brd 192.168.1.63 scope global eth0

    inet 192.168.1.7/26 brd 192.168.1.63 scope global secondary eth0

    inet6 fe80::4569:7d7a:108d:c2ad/64 scope link
       valid_lft forever preferred_lft forever

Я добавил vlan в netplan:

root@pro-rpi-02:/# more /etc/netplan/01-netcfg.yaml
network:
  version: 2
  renderer: networkd
  ethernets:
    eth0:
      dhcp4: no
      addresses:
        - 192.168.1.2/26
      gateway4: 192.168.1.10
      nameservers:
          addresses: [192.168.1.24]
          search: [hello.home]
  vlans:
    vlan.8:
      id: 8
      link: eth0
      dhcp4: no
      addresses:
        - 192.168.8.2/24

А теперь самое интересное:

root@pro-rpi-02:/cluster/Radius# ip addr sh
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether dc:a6:32:b3:45:e0 brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.2/26 brd 192.168.1.63 scope global eth0
       valid_lft forever preferred_lft forever
    inet 192.168.1.5/26 brd 192.168.1.63 scope global secondary eth0
       valid_lft forever preferred_lft forever
    inet6 fe80::4569:7d7a:108d:c2ad/64 scope link
       valid_lft forever preferred_lft forever
3: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel state DOWN group default qlen 1000
    link/ether dc:a6:32:b3:45:e1 brd ff:ff:ff:ff:ff:ff
4: vlan.8@eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
    link/ether dc:a6:32:b3:45:e0 brd ff:ff:ff:ff:ff:ff
    inet 192.168.8.2/24 brd 192.168.8.255 scope global vlan.8
       valid_lft forever preferred_lft forever
    inet 192.168.8.112/24 brd 192.168.8.255 scope global secondary noprefixroute vlan.8
       valid_lft forever preferred_lft forever

Кто-нибудь может объяснить, почему я получаю адрес dhcp 192.168.8.112/24? Или хотя бы подскажите, где я могу начать искать?

UPDATE 1, как и просили, вот результат, пока не вижу ничего, что могло бы мне помочь :)

Потратив X часов на попытки найти здесь исправление, я решил просто отключить службу dhcpcd : 

root@pro-rpi-02:~# systemctl status dhcpcd.service
● dhcpcd.service - DHCP Client Daemon
     Loaded: loaded (/lib/systemd/system/dhcpcd.service; disabled; vendor preset: enabled)
     Active: inactive (dead)
       Docs: man:dhcpcd(8)

Теперь все работает как Я бы хотел, чтобы он работал: 

root@pro-rpi-02:~# more /etc/netplan/01-netcfg.yaml
network:
  version: 2
  renderer: networkd
  ethernets:
    eth0:
      dhcp4: no
      dhcp6: no
      addresses:
        - 192.168.1.2/26
      gateway4: 192.168.1.10
      nameservers:
          addresses: [192.168.1.24]
          search: [hello.home]
  vlans:
    vlan8:
      id: 8
