I prefer to download first, before installing any updates, making it 5 steps:
Update the sources
apt-get dist-upgrade -d
I have had issues in the past with a loss of network connectivity mid update causing serious issues.
I’ll try above method definitely. It makes sense. Bad network connecting during the upgrade process causes some time irreversible problems.
