Package: apt
Version: 2.1.12
Severity: normal


The release notes tell people that they should basically use

apt-get upgrade
apt-get dist-upgrade

But people tend to rather use

apt upgrade
apt dist-upgrade

I guess essentially because apt provides progression indication.

The problem is that these are not equivalent: apt upgrade will attempt
to install additional packages required by newer versions of existing
packages. That can lead to conflicts/breaks with other existing
packages, and thus get into all the complexity that using apt-get
upgrade first avoids.

The problem is then that actual users end up in *other* situations than
what would typically be tested according to the release notes.

We can try to insist on making people use apt-get upgrade instead of apt
upgrade, but I believe that can only work if apt-get provides at least
*some* progress indication, especially for distribution upgrades, whose
duration are quite unknown before doing them.

Alternatively, we could fix apt into behaving really like apt-get, to
avoid that discrepancy between what debian developers actually test and
what users actually use.
