Public bug reported:
When installing .tar.gz packages with pip on python2.7 the attempt to
install them fails after upgrade to python2.7 amd64 2.7.18-1~20.04.5
installation of the same packages with python2.7 2.7.18-1~20.04.4 was
successful.
Reproducer:
sudo apt-get install -y python2.7 python2.7-dev python-pip-whl
sudo ln -sf python2.7 /usr/bin/python
export PYTHONPATH=`echo /usr/share/python-wheels/pip-*py2*.whl`
sudo --preserve-env=PYTHONPATH python -m pip install --upgrade pip setuptools
wheel
pip install --pre tlslite-ng
Results in:
Collecting tlslite-ng==0.8.0-beta5
