Let us dug it step by step:

In fact, my latexmk configuration, aka, `/home/werner/.latexmkrc` was
set by me very long ago.

See below:

$ cat test.tex
\documentclass{article}

\begin{document}

This is a test.

\end{document}

%%% Local Variables:
%%% mode: latex
%%% TeX-master: t
%%% End:

$ latexmk -C test
$ latexmk -pv test

It's very strange that I don't have any acroread related config in
`/home/werner/.latexmkrc`, why does it complain the following:

sh: 1: acroread: not found


See below for the real config of latexmk:

$ grep -Ev '^[ ]*(#|$)' ~/.latexmkrc
$show_time=1;
$pdf_mode = 4;
$postscript_mode = $dvi_mode = 0;
$lualatex = "lualatex -shell-escape -file-line-error -halt-on-error
-interaction=nonstopmode -synctex=1 %O %S";
$bibtex = "bibtex %O %S";
$bibtex_use = 2;
$makeindex = "makeindex %O -o %D %S";
$silence_logfile_warnings = 1;
   add_cus_dep( 'acn', 'acr', 0, 'makeglossaries' );
   add_cus_dep( 'glo', 'gls', 0, 'makeglossaries' );
   $clean_ext .= " acr acn alg glo gls glg";
   sub makeglossaries {
      my ($base_name, $path) = fileparse( $_[0] );
      pushd $path;
      my $return = system "makeglossaries", $base_name;
      popd;
      return $return;
   }
add_cus_dep( 'svg', 'pdf', 0, 'makesvg2pdf' );
sub makesvg2pdf {
    system( "inkscape \"$_[0].svg\" --export-pdf=\"$_[0].pdf\"" );
}
