I run a new installation of Minimal image based on Debian Buster on Raspberry Pi 3B.

sudo apt-get update gone as usuall - 1-2 minutes. However, sudo apt-get upgrade is running already 1:30 or so. And still not finished.

I run another console and see that it's working extremely slow. I saw that login prompt appeared only when a new line in the upgrade window appeared. Further activity in the second shell was related to the activity in the first one. It looks like my RPi virtually stuck with upgrade. But CPU looks almost free of any load:

What can I do to debug the process?

This happens because of:

=> Slow mirror server.

=> Slow internet speed.

=> Very slightly because of broken packages.

    Slow connection just makes the upgrade take longer. It doesn't stall the entire system.
