I disagree and here is why.
That the apt resolver failed and the dose3 explainer succeeded is *not* useless
information. It tells you, that a solution exists but apt is able to find one.
This in turn tells you, that you might want to choose a different resolver. If
the apt explainer were the default, then you would not be able to figure out
that the problem is not a dependency problem but instead a problem with the apt
resolver.
To your second argument: indeed the reason why dose3 fails might be a different
one because of which apt fails. But that should not matter. Because (in theory)
as long as the dose3 explainer fails, you simply cannot get a solution from
apt. So even if the reason is different, you have to fix the reason given by
the dose3 explainer anyways, even if it's a different reason from the one that
apt had. So why is it then a problem that the reason given by the dose3
explainer might be a different one?
Thus, I'm tagging this wontfix. But if you think that my arguments are
unfounded, please tell me why. :)
Another reason why the dose3 explainer is the default is, that its output is
much more human readable than the output of the apt explainer. Do you disagree?
Thanks!
