I have 2 IP adresses

Hello
Since ~2 months (before upgrading to OMV4) when OMV boot, I have 2 IP on eth0
192.168.0.40 and 192.168.1.50 (old conf)

I’m able to remove the second one with ip addr del 192.168.1.50/24 dev eth0 but if I reboot, the IP is back and broke routes btw :-/

/etc/network/interfaces as no references to 192.168.1.50

Any idea ?

Can you put the first command in a code tag ?

IP is static (I have already delete the old leases but don't fix the problem)

# The loopback network interface
auto lo
iface lo inet loopback


# eth0 network interface
auto eth0
allow-hotplug eth0
iface eth0 inet static
    address 192.168.0.40
    gateway 192.168.0.1
    netmask 255.255.255.0
    dns-nameservers 89.2.0.1
    dns-search lan
iface eth0 inet6 manual
    pre-down ip -6 addr flush dev $IFACE

EDIT : For the first command I have a "500 Internal Server Error"

boot.txt

dpkg -P dhcpcd5
apt-get install dhcpcd5

Solved my issue
EDIT : Thank you for your help, after a new reboot, everything is all right and 192.168.1.50 is definitely gone
