I reviewed the log and I tend to agree with you that using the "interest"
variant is the correct course of action.
The cases where a postinst will require dbus to have loaded new policies
provided by one of its dependencies are probably fairly rare (possibly
even non-existent in Debian) but we should not rely on this being the case
because your explanation of the actual behaviour makes sense.
It would be nice if apt could be smarter and fallback to
"dpkg --configure --pending" when the single "dpkg --configure foo"
that it invokes fails...
At the same time, dpkg could be nicer and accept to configure other
packages when it's required to achieve the goal requested by the caller.
Hopefully this would not confuse apt too much since apt tracks what
dpkg does via the status-fd anyway. Is this realistic or only
wishful thinking ?
Only the latter solution seems to satisfy our requirements in terms of
upgrades...
Cheers,
