Hi, Line 32 on the Makefile has a broken link in a comment: https://lintian.debian.org/tags/manpage-has-errors-from-man.html I found a google cached copy: https://webcache.googleusercontent.com/search?q=cache:_t5GTxkpo5wJ:https://lintian.debian.org/tags/manpage-has-errors-from-man.html The copy is very recent (21-aug-2020), so it may be broken only temporarily. Alex.
