Comment 2 for bug 1886237

Its reproduced setuptools side. setuptools (48.0.0 onwards) adopt the distutils from std lib but customized version of ubuntu distutils are lost. setuptools 49.1 has disabled the distutils adoption and gate is working fine with that - https://review.opendev.org/#/c/739294/1
