To clarify: this is a bug in urllib3 as bundled in python-pip, that shows up only when PyPI is unavailable. Pybuild sets https_proxy=https://127.0.0.1:9/ to forcefully make PyPI unavailable during the package build.
(There's probably a sibling bug lurking around: why is python3-virtualenv attempting to pip install stuff from PyPI instead of using the bundled python-setuptools wheels?) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1743886 Title: TypeError: unsupported operand type(s) for -=: 'Retry' and 'int' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/python-pip/+bug/1743886/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
