CROSS_ARCH=arm64
if [ "$(dpkg --print-foreign-architectures | grep -c $CROSS_ARCH)" -ne 1 ] ; then
    sudo dpkg --add-architecture $CROSS_ARCH
    sudo sed -i 's/^deb \(.*\)/deb [arch=amd64] \1/g' /etc/apt/sources.list
for f in $(ls /etc/apt/sources.list.d/*.list); do
    sudo sed -i 's/^deb \(.*\)/deb [arch=amd64] \1/g' \$f
done
for f in $(ls /etc/apt/sources.list.d/*.sources); do
    echo "Architectures: amd64" | sudo tee -a \$f
