MarsSeed [1] filed a deletion request for live-usb-install [2]: Broken Python2 pkg, upstream discontinued since 2017. [a]
I recommend deletion. It does not seem to be worth the effort to try to develop it to make it work, when there are so many currently maintained and working alternatives for the same use case.
