Title:
Temporary failure in name resolution in Python 3.7.2
Status in python3-defaults package in Ubuntu:
New
Bug description:
My Python application works in 18.10 fine, but when upgrading to 19.10
for development reasons the same script produces the errors reported
below. I have checked on the Python bug tracker and there are no
related bug reports.
