problem on ubuntu bridges installation

I'm following the instructions, but it is not working.

Here is my original 00-installer-config.yaml file:

# This is the network config written by 'subiquity'
network: ethernets: enp2s0: dhcp4: true enxc21a33ea90c1: dhcp4: true version: 2

...and this is how it looks after edits:

# This is the network config written by 'subiquity'
network: ethernets: enp2s0: dhcp4: no enxc21a33ea90c1: dhcp4: no version: 2 renderer: NetworkManager bridges: br0: interfaces: [enp2s0] addresses: [192.168.8.108/24] nameservers: addresses: [8.8.8.8,4.4.4.4]

I got this error after running sudo netplan apply:

/etc/netplan/00-installer-config.yaml:11:15: Error in network definition: expected mapping (check indentation) br0:

Can anyone advise what is wrong?

Netplan (using YAML) is picky about indentation. Try formatting the file exactly like this, and see if it works:

# This is the network config written by 'subiquity'
network: ethernets: enp2s0: dhcp4: no enxc21a33ea90c1: dhcp4: no version: 2 renderer: NetworkManager bridges: br0: interfaces: [enp2s0] dhcp4: no addresses: [192.168.8.108/24] nameservers: addresses: [8.8.8.8, 8.8.4.4]

The main error I can spot is that you lack indentation between br0: and interfaces:.

Also, not that the secondary Google DNS is 8.8.4.4. and not 4.4.4.4.
