Hi, I can confirm this bug. Step to reproduce. Put this in /etc/pip.conf:
[global] timeout = 60 index-url = http://mirror.dfw.rax.openstack.org/pypi/simple trusted-host = mirror.dfw.rax.openstack.org extra-index-url = http://mirror.dfw.rax.openstack.org/wheel/ubuntu-18.04-x86_64 then any pip install command will fail. For example: virtualenv --no-download venv ./venv/bin/pip2 install -U <SOMETHING> It'd be nice to have this fixed for Buster. Cheers, Thomas Goirand (zigo)
