Ubuntu server No internet connection

Question

Help me please. 3-rd day trying.

After installing ubuntu server there is no internet connection. ipconfig not installed and no possibility to install it because of internet connection

So. there is 3 interfaces (picture) I`m trying to config netplan

network:
  ethernets:
    enp3s0:
      dhcp4: true
      dhcp6: true
    enp5s0:
      dhcp4: true
  version: 2

But there is no still internet. I tried many options from the Internet, but apparently I don't understand something, please tell me smart people.

sudo lshw -C network

ls -al /etc/netplan
