Thanks for a reminder --- something like that. I haven't worked out
whether there is a dpkg correctness bug here. There are certainly
usability and documentation bugs.

>From doc/triggers.txt:

Status Pending Awaited Satisfies Remedy
triggers triggers Depends

unpacked never maybe No postinst configure
c.-failed never maybe No postinst configure (when requested)
t.-awaited yes always No postinst triggered + fix awaited pkg(s)
t.-awaited no always No fix awaited package(s)
t.-pending always never Yes postinst triggered
installed never never Yes n/a

Triggers are not part of policy[1] yet. But anyway, this requirement
seems sensible --- a package in python triggering python-support, for
example, is not usable until python-support creates some symlinks as

The usual UI for satisfying unpack-time dependencies is that dpkg
leaves it to a higher-level package manager. A higher-level package
manager makes sure the pre-dependencies are fully installed before the
pre-dependent packages are unpacked and dpkg only checks this.

This is in contrast to configuration-time dependencies for which
ordering of triggers is taken care of automatically by
dpkg --install/--configure (though I haven't checked the details.
I would hope --no-triggers would mean that the triggers-awaited state
would percolate through the dependency tree, but I couldn't find code
for that).

The upshot: iiuc one needs to run

dpkg --triggers-only <packages pre-depended upon>

to satisfy an unpack-time dependency, by design.

Hope that helps,
