in developing Linux From Scratch for checking test suite i run this command:

and at last it shows some errors as you seen attachment, i'll be merciful
to guide me about this problem.

Please don't send screenshots of text; just send the text. As far as the actual bug goes, what is in gnulib-tests/test-update-copyright.sh.log?
