It has been a few years since I last touched a Linux box. Tonight I decided to install an Ubuntu Server and wanted to give it a static IP address. As I went to /etc/network and wanted to edit the interfaces file, I realised that things have changed. Now you configure the NICs using netplan.
So I fired up putty after reading some examples on how to do this and got hit by this error when trying to apply the configuration:
Invalid YAML at /etc/netplan/eth.yaml line 10 column 0: found character that cannot start any token
Turns out that I had used tab to do indents of the config. I change my tabs to spaces and it all worked out. My config is this now:
network: version: 2 ethernets: ens160: addresses: [ "10.10.10.22/22" ] gateway4: 10.10.10.1 nameservers: addresses: [18.104.22.168, 22.214.171.124]
It is applied using:
sudo netplan apply
If you do not receive any errors verify with
