Fix apt-get update on Ubuntu 20.04 under WSL2

I recently cannot run a apt-get update resulting in a kind of - weird - temporary network issue...

Execute the following lines to adress this issue:

wget https://gist.githubusercontent.com/TeddyBear06/f2524b8b2d0e15336c4f8463127f5332/raw/cc54c875310d7be4e768bf6c50df496ac4294cbb/fix_apt_update_under_WSL.sh
chmod +x fix_apt_update_under_WSL.sh
sudo ./fix_apt_update_under_WSL.sh

Initial idea from Sundar Narasiman.

fix_apt_update_under_WSL.sh
# Generate a file to avoid WSL to overwrite again and again /etc/resolv.conf file
echo "[network]" >> /etc/wsl.conf
echo "generateResolvConf = false" >> /etc/wsl.conf
# Set /etc/resolv.conf new content (use your favorite DNS resolver)
echo "nameserver 8.8.8.8" > /etc/resolv.conf
# Protect /etc/resolv.conf from overwriting (see https://man.archlinux.org/man/chattr.1.en)
chattr -f +i /etc/resolv.conf
