    how is this different to the question you already asked [here](https://askubuntu.com/questions/1346288/sudo-apt-update-error) 10 minutes previously which has an answer? – graham Jun 16 '21 at 15:18
  • @sia you have some problem with the *internet connection*. I have no clue about wsl 2 so i cannot help. – AlexOnLinux Jun 16 '21 at 20:01

DNS resolution error is quite common in WSL2

So execute the below commands

echo "[network]" | sudo tee /etc/wsl.conf
echo "generateResolvConf = false" | sudo tee -a /etc/wsl.conf
sudo rm -Rf /etc/resolv.conf
echo "nameserver 8.8.8.8" | sudo tee /etc/resolv.conf 
sudo chattr +i /etc/resolv.conf
