I've just hit this trying to do a netinstall of vivid. Looking at the source, algorithm 10 is sha512. The binary for the installer is built with --enable-minimal, which disables sha512, but then it isn't specifically enabled. Attached patch to enable it. I've tested this by building it myself and using wget to replace the included binary with mine, I successfully completed the install.
