I ran tests of "apt clean; apt update; apt --download-only
install --install-recommends tde-trinity; apt clean" twice
each on three different VPSs, each in a different data center
in a different US state. Prior to testing the VPSs had no
X Windows and no TDE other than the keyring. Debian Buster.
Speeds for the TDE portion of the downloads appeared to be
roughly 10-35MBps (not bps).
With TDE r14.0.x I encountered no download errors.
I ran the six tests again, this time against TDE PSB. Again
no download errors on TDE but I did get one download failure
one time from Debian:
E: Failed to fetch
http://ftp.us.debian.org/debian/pool/main/p/poppler-data/poppler-data_0.
4.9-2_all.deb
Undetermined Error [IP: 208.80.154.15 80]
E: Some files failed to download
I conclude this is a network or apt problem rather than a
TDE problem. It occurs more frequently for Felix so it
might be a local router problem such as NAT table exhaustion.
I looked at:
https://bugs.debian.org/cgi-bin/pkgreport.cgi?dist=stable;package=apt
and there are HUNDREDS of open bugs. I couldn't find one
that matched this but I don't see any point in trying to
report an intermittent issue that might be a communication
problem rather than an apt bug.
I don't think there's anything more that TDE can do. The
workaround is to hit up-arrow then enter if download fails.

If this happens frequently for Felix, it may be a good idea to split the
update so that first apt calls "apt upgrade --download-only", and only
when everything is successfully downloaded does the package upgrade
continue.
