Comment 0 for bug 1969809

I'm using the ua tool (version 27.7~16.04.1). I'm unable to enable the esm-infra service because a couple of the packages that I have installed have been completely removed from the launchpad server. Specifically:

deb http://ppa.launchpad.net/jonathonf/ffmpeg-3/ubuntu xenial main
deb http://ppa.launchpad.net/jonathonf/python-3.6/ubuntu xenial main

When I remove these package definitions from /etc/apt/sources.list.d/ the command succeeds.

I've attached a log file that includes this stack trace.
