Code:
/usr/lib64/ruby/3.1.0/rubygems.rb:265:in `find_spec_for_exe': can't find gem asciidoctor (>= 0.a) with executable asciidoctor (Gem::GemNotFoundException)
from /usr/lib64/ruby/3.1.0/rubygems.rb:284:in `activate_bin_path'
from /usr/bin/asciidoctor:23:in `<main>'
asciidoctor fails to work. I upgraded to 2.0.17.
