netplan apply does not change the IP address

ok, my file is located at /etc/netplan/50-cloud-init.yaml
I changed the IP address as a static IP address as following:

network:

  version: 2 



  renderer: netwokrd



  ethernets:



    dhcp4: no

    dhcp6: no

    addresses: [10.0.2.100/24]

    gateway4: 10.0.2.1

    nameservers:

       addresses: [10.0.2.100]

Then, I typed sudo netplan apply, and there was not any error message.
BUT, when I typed ifconfig, it still remail past IP address on enp0s3.
Do you guys know why this happen?

Netplan is fussy about how .yaml files are formatted. Don't try to "pretty-fy" them.

Is 50-cloud-init.yaml the only .yaml file in /etc/netplan?

So edit your .yaml file to look like this...

network:

  version: 2 

  renderer: networkd <-- note the correct spelling

  ethernets:

    enp0s3: <-- identify the proper interface

      dhcp4: no

      dhcp6: no

      addresses: [10.0.2.100/24]

      gateway4: 10.0.2.1

      nameservers:

        addresses: [10.0.2.100] <-- this is probably the wrong address

        addresses: [8.8.8.8, 8.8.4.4] <-- use something like this instead

then do:

sudo netplan --debug generate  # generate the config files

sudo netplan apply            # apply the new configuration

reboot                        # reboot the computer

and recheck your ifconfig output.

Note: if it was me, I'd let NetworkManager manage this interface, and set the static address information into the "Wired Connection" profile.

network:

  version: 2

  renderer: NetworkManager

then do:

sudo netplan --debug generate  # generate the config files

sudo netplan apply            # apply the new configuration

reboot                        # reboot the computer

since the netplan config is in /etc/netplan/50-cloud-init.yaml it is likely this is a cloud image which has no NetworkManager installed.

Why do you must reboot? Is there any other way?

Dec 17 '18 at 9:19

@Nimitack technically, the sudo netplan -debug generate and sudo netplan apply commands should do it, but I've seen cases where it didn't, and a reboot will actually start with the netplan configuration you've set, and you can confirm that it's working as expected.

I see this issue on vmware machine and on virtual box.. when I install ubuntu 18.04... I really need this to NOT reboot.. I couldn't find anything about this on the web.. this is pretty basic stuff, static IP. I don't understand why to reset it.. it's not hardware or so..., Linux is all about NOT rebooting right?

– Nimitack
Dec 18 '18 at 12:48

@Nimitack I'm confused. I indicated that a reboot is not mandatory, however, it MAY be required if the sudo netplan apply doesn't do it.
