You can replace VERSION=$(curl --silent $URL |grep '"tag_name":' |sed -E 's/.*"([^"]+)".*/\1/') with VERSION=$(curl -L --silent $URL |grep '"tag_name":' |sed -E 's/.*"([^"]+)".*/\1/') so that curl follows redirects and works with the latest Github API changes.

Just made the change, thanks it makes sense
