[Bug 1956039] Re: BADSIG 871920D1991BC93C Ubuntu Archive Automatic Signing Key (2018) <ftpmaster at ubuntu.com>

Hmm, I did find what was causing it. I had a proxy configured for apt pointing at apt-cacher-ng on a local system.
When I removed the proxy from the configuration, apt had no issues downloading lists.
