To upgrade existing packages use "apt-get update && apt-get upgrade".

"apt-get dist-upgrade" is only required in complex situations, e.g.
where other packages must be added or removed to accommodate package
upgrades.  This normally only happens when upgrading to a new release.

Whenever "apt-get dist-upgrade" is needed it is important to carefully
check what apt-get proposes to do and determine to your own satisfaction
that the proposed actions are sensible, safe, and appropriate.

The information from "apt-get rdepends ..." and/or "aptitude why ..."
is the first step on the road to determining whether this is a Devuan
or Debian or PEBCAK problem.
