Hi Mohammed,
I ran into a similar issue when doing a docker installation a few months back. If your setup.cfg file was created/modified/saved on a Windows machine then check if there are any Windows newline characters in the file; the installation process will fail if Windows newline characters exist. Support had recommended the following to me:
"I would suggest recreating the setup.cfg file under your Linux system directly. See what happens once you run that command again. Or you could just replace all \r\n newline characters with \n"
Would suggest looking through your setup.cfg file, replace any Windows newline characters and see if that allows the command to complete.
