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.
NAICT, that's exactly what apt/apt-get/aptitude is/are doing. They exit right after the failed package fetch info shows up onscreen. I just up-arrow, <enter>, it fetches the missing package, and installs everything.
