Devuan, as a fork of debian that uses sysvinit (or another– your choice), still uses debian-based utilities. I come from the Fedora/Red Hat/CentOS rpm-based family of distributions, and I struggle with the dpkg-based package management on occasion.
I really dislike how the software upgrades will sometimes pause in the middle, to display the changelog. If I wanted a changelog, I’d go read it! When I issue a command to update packages, I want to walk away, and come back, and it be done, not get stuck at 20% because openssh changed some defaults and wants to tell me. It emails me anyway! I find the defaults of apt-get to be not sane.
Here is how to configure apt-get to run without pausing to display duplicate information or ask you questions.
export DEBIAN_FRONTEND=noninteractive apt-get -q -y upgrade
