raspotify: raspotify doesn't support architecture 'arm64'

I’ve installed Ubuntu 64 bits 18.04.4 LTS on my raspberry pi and I faced some issues to install raspotify on it: > curl -sL https://dtcooper.github.io/raspotify/install.sh | sh Raspotify installer only runs on a Raspberry Pi > sudo apt-get update ... N: Skipping acquire of configured file 'main/binary-arm64/Packages' as repository 'https://dtcooper.github.io/raspotify raspotify InRelease' doesn't support architecture 'arm64'

I found this article on the net but it seems a bit dirty: https://thewayeye.net/posts/installing-raspotify-arm64/

Do you plan to make raspotify compatible with Ubuntu 64 bits ? Or do you have tips to make it run ?
