I tried apt-get clean, apt-get autoclean, apt-get remove python3-setuptools, dpkg --remove python3-setuptools, apt-get install -f, dpkg -P --force-remove-reinstreq, dpkg -P --force-all --force-remove-reinstreq and dpkg --purge, but none of them worked.

Output of sudo dpkg -P --force-all --force-remove-reinstreq python3-setuptools
