UBUNTU_CODENAME=jammyI am using Ubuntu 20.0.4 and originally set up a static ip address using a netplan yaml file like this:
Code:$ cat /etc/netplan/01-network-manager-all.yaml
network:
renderer: networkd
ethernets:
eno1:
addresses:
- 10.168.17.200/24
nameservers:
addresses: [8.8.8.8, 8.8.4.4]
routes:
- to: default
via: 10.168.17.1
version: 2This worked fine.

At some point I unplugged the cable, then later connected it again and realised that eno1 no longer had an ip address

I suspect in between times there had been an (auto probably - I can't remember explicitly doing one, but I may have done) update, but I cannot be certain.

I executed the command:
$ sudo netplan apply
which came up with a Warning about yaml file permissoins, so I changed the permissions to 600 and ran the netplan apply command again.

This came up with a warning:
WARNING:root:Cannot call Open vSwitch: ovsdb-server.service is not running.

So I managed to connect (bit of a checken and egg issue this) to the internet via wireless and install opwnvswitch-switch-dpdk.

Now when I run netplan apply there are no warnings or errors, but the ip address on eno1 is not set.

Anyone know what might be happening here ?
Any ideas on how I can go about debugging the issue ?
