I have not figured out the difference between apt(8) and apt-get(8).  It 
looks like the former uses the latter as a back-end (?).  I use apt-get(8).


Always backup before doing updates; especially kernel upgrades.


When I want to upgrade, re-install, or install packages, I start with 
'apt-get update'.


I would have done 'apt-get upgrade ...' instead of 'apt install ...'.  I 
then reboot.


If there are packages that have been kept back, I do 'apt-get 
dist-upgrade' and then reboot.


If I want to re-install a package for whatever reason, I do 'apt-get 
remove ...' or 'apt-get purge ...'.  If I'm suspicious, I reboot.  Then 
I do 'apt-get install ...' and reboot.
