Thanks,

I did try to restart the phone already with no effect.

None of my filesystems is full (or close enough).

What I managed in between is to monitor some behavior during this hang in the download process:

Zero-byte files for all packages are created in /home/user/MyDocs/.apt-archive-cache/partial/. --- They stay zero bytes for all their lifetime and are deleted right before the next one is created so that always only one file is present. Thus it seems the download process itself is failing somehow.

The tool that is actually doing that is "/usr/lib/apt/methods/https" invoked by "/usr/libexec/apt-worker backend /tmp/apt-worker.to /tmp/apt-worker.from /tmp/apt-worker.status /tmp/apt-worker.cancel BM".

Thus what is the expected behavior of that tool? Where are those files supposed to be stored when they are completely downloaded? Is there a way to get potential error messages out of this tool or the apt-worker process?
