Comment 10 for bug 1815231

Confirming, this issue went away by Friday evening. Thanks for taking a look. We didn't make any changes our side, and we aren't caching anything ourside (not even ubuntu images).

The file it complainedd about http://archive.ubuntu.com/ubuntu/pool/main/p/python-apt/python-apt_1.6.3_amd64.deb still doesn't exist, so perhaps something in the ubuntu base build needed to be updated in parallel with the rename of the python-apt deb file and we caught it whilst it was out of sync. I'm purely guessing.
