Especially on the Raspberry Pi, it is quite often for me to lose connection while updating. I know some people setup
tmux sessions so that they can easily reconnect. I’m not good at remembering to do this. Angus and Cas on StackExchange shared that to resume a stopped update…
sudo kill $(pgrep dpkg) sudo dpkg --configure --pending sudo apt install -f
Which will then configure the packages that have already been installed but not configured yet and finish installing packages.
