Comment 0 for bug 1990586

Impact
------
Users who manually run sudo apt dist-upgrade without paying attention can remove essential parts of their system

Test Case
---------
This test case won't work as well if phasing is set to 0% or 100%

Set /etc/machine-id to 2c030cfce3b4487f9810f12a3ac6e87c

sudo apt update
sudo apt dist-upgrade

Workaround

Don't run sudo apt dist-upgrade. Just run sudo apt upgrade
Or use Update Manager or the Ubuntu Store to apply updates
