LucidaSans-Typewriter is supplied in the xv6-riscv-src-booklet directory.
To my knowledge, Lucida font family has a commercial license and cannot be freely distributed.
A very close alternative would be the SourceCodePro-Regular font: https://github.com/adobe-fonts/source-code-pro/ which is under the SIL Open Font License, and may be distributed freely (with the license).
See https://xv6-64.gitlab.io/xv6-64/xv6-64.pdf for a sample with the xv6-64 version.
