That error message looks strange. It looks like you're installing the libnettle7 package for amd64, but there's _another_ instance of that package that's _also_ for amd64? Did you download the .deb file manually? libnettle7 should exist in Ubuntu 20.04 according to https://packages.ubuntu.com/focal/libnettle7.
