"man a2ping" gives man page, no problem

Linux Fedora 32, export only PATH with TeX Live binary (file
"/etc/man_db.conf" without any modification, default config).
$ echo $PATH
/opt/texlive/2020/bin/x86_64-linux
$ echo $MANPATH
# nothing, no MANPATH variable
$ manpath
/opt/texlive/2020/bin/man     # option 2
$ manpath -d
path directory /opt/texlive/2020/bin/x86_64-linux is not in the config file
  adding /opt/texlive/2020/bin/man to manpath

Linux Fedora 31 (TeX Live 2019, equivalent as Fedora 32, "man" linked
as default, option 1)
$ echo $PATH
/opt/texlive/2019/bin/x86_64-linux
$ echo $MANPATH

$ manpath
manpath: warning: $MANPATH set, prepending /etc/man_db.conf
/opt/texlive/2019/bin/x86_64-linux/man     # option 1
$ manpath -d     # more verbosity than Fedora 32
path directory /opt/texlive/2019/bin/x86_64-linux is not in the config file
but does have a ../man, man, ../share/man, or share/man subdirectory
  # !!! important !!!
adding /opt/texlive/2019/bin/x86_64-linux/man to manpath
