The latest HTMLDOC, open-source HTML conversion software, now can be easily installed in Ubuntu 16.04 and higher via Snap package.

HTMLDOC is a program that reads HTML and Markdown source files or web pages and generates corresponding EPUB, HTML, PostScript, or PDF files with an optional table of contents.

Type user password (no asterisks feedback) for sudo prompt and hit Enter.

Then install the software package via command:
