dhcp fails on br0, new configuration
Solution 1:
There are a few errors in your netplan-configuration.
- Duplicate network sections
- Duplicate version keys
- I do not think you are supposed to enable DHCP on the interface wlp0s20f3 but rather on the bridge only.
Like this:
network:
version: 2
renderer: NetworkManager
ethernets:
wlp0s20f3:
dhcp4: false
bridges:
br0:
interfaces: [wlp0s20f3]
dhcp4: yes
