Environment

Windows build number: Microsoft Windows [Version 10.0.19041.329]
Your Distribution version: Debian GNU/Linux 10 \n \l
Whether the issue is on WSL 2 and/or WSL 1: Linux version 4.19.104-microsoft-standard (oe-user@oe-host) (gcc version 8.2.0 (GCC)) #1 SMP Wed Feb 19 06:37:35 UTC 2020
Same problem in WSL 1 and WSL 2

Steps to reproduce

I just do sudo apt update

Expected behavior

Get packages updates

Actual behavior

After waiting for network timeouts, more or less 10 seconds, this is the output for sudo apt update:

luke@DESKTOP-U264O87:~$ sudo apt update

Obviously with this fail, sudo apt upgrade returns nothing to upgrade.

What I already tried

1. Deleted symlink in /etc/resolv.conf pointing to that in /run/resolvconf/resolv.conf

2. Created /etc/wsl.conf file to stop auto-generation of /etc/resolv.conf which i edited putting only nameserver 8.8.8.8

3. Set up eth0 interface by getting gateway ip from vEthernet(WSL) card by this PowerShell script:

$gateway_ips = Get-NetIPAddress -InterfaceAlias "vEthernet (WSL)" | select IPAddress
$gateway_ip = $gateway_ips[1].IPAddress
Write-Output "Gateway (local WSL adapter) IP is: $gateway_ip"

because with my default network gateway at 192.168.1.1 it didn't work.
and then I configured eth0 interface with:
sudo ip a add 172.23.64.1/255.255.240.0 dev eth0
sudo ip route add default via 172.23.64.1 and
ip link set dev eth0 up

so that now ip r returns:

default via 172.23.64.1 dev eth0
172.23.64.0/20 dev eth0 proto kernel scope link src 172.23.64.1

but Internet is still not working.
