libcupt2-0 declares that it Recommends
	libcupt2-0-downloadmethod-curl | libcupt2-0-downloadmethod-wget
Presumably this is not a Depends because it is also possible to write
your own download handler. Eugene, do you think it would make sense
to have a libcupt2-0-downloadmethod virtual package so this could say
	Depends: libcupt2-0-downloadmethod-curl | libcupt2-0-downloadmethod
?
Thanks for writing,
Jonathan

This. Manuel, you probably switched installing Recommends off which is
not a good idea since Recommends is for "all but unusual installations".
So, install the 'libcupt2-0-downloadmethod-curl' package, which should
have been installed by default.

These are put to Recommends by intent, because:
1) there are file:// and copy:// built-ins;
2) one can, as you just said, write a custom download method;
3) finally, on some embedded system you can in theory install download
 methods, download some unchangeable suite's cache, remove Cupt download
 methods (along with wget/libcurl) and they play with repository analysis
 and simulations.

Yeah, good point. :)
The tweak below would have made it harder to forget.
Thanks for explaining,

OK, thanks for the fix.

Apart from acknowledging that it's my fault, I've been using all of my
systems with Recommends off by default for many years, without major
hiccups.
I honestly don't think that the number of people switching it off is
less than the ones writing downloading methods by hand... not even for
cupt, but for any other packaging tool in Debian.
And I guess that you can use "provides"/virtual packages for the case
that you mention. If somebody is going to the trouble of writing such
a method, creating a virtual package is a minor issue.
Cheers.

Maybe the package description should mention that you might want a
download method if planning to use cupt with a sources.list using
protocols other than file:// and copy://.
The relevant package is libcupt2-0, and I don't think many people read
its package description, but that information could go in the cupt
description anyway. How about this?

Here "manager" is an odd sort of compromise between 'method' and
'handler'. It should say 'method'. Sorry for the confusion.

I think that the patch to the source file that you mentioned before
explaining the problem is the best way.
"There is not handler for blah... please install one of these packages
[ ... ] or provide your own."
Or Depend (not Suggest) on one of those packages, and let the people
who want to play around with cupt change the control file to depend on
other download methods.
Anyway, I just wanted to bring the issue to your attention, you know
better than me how to fix it :)
Cheers.

In policy-conforming Debian world we wouldn't need this, but it
doesn't hurt either, so applied for 2.5.4, thanks.
