Should have got x86_64, but got aarch64.

It's got the wrong asset for linux_amd64

        #choose from asset list
        URL=""
        FTYPE=""
        case "${OS}_${ARCH}" in

Ahh definitely a bug. it currently checks amd64 is go convention, then falls back to looking for 64 - hence this bug. installer needs to check convention too (x86_64)
