[Bug 2067228] [NEW] ncurses/i386 autopkgtest failure

[Bryce Harrington]

Public bug reported:

The i386 autopkgtests for ncurses are failing in oracular due to build
dependency confusions.

https://autopkgtest.ubuntu.com/results/autopkgtest-
oracular/oracular/i386/n/ncurses/20240526_110804_4d872@/log.gz

It looks like this same sort of issue occurred in noble (LP: #2052951),
and was addressed by simply disabling the manpage-references subtest for
i386.  It looks like ncurses 6.5-2 was sync'd in instead of merging with
the delta, thus dropping the workaround.

However, the log of this failure differs a bit from the prior issue, in
that all of the subtests are failing, and the error messages are a bit
different:


267s autopkgtest [11:07:52]: test infocmp-dumb: preparing testbed

268s autopkgtest [11:07:53]: ERROR: | E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

One option might be to do as in LP: #2052951, and disable all subtests
for i386, but I wonder if there are better options to consider that
would allow the testsuite to run?  I'm not sure I understand precisely
what is causing the i386/amd64 confusion, but perhaps this is a known
situation with an established way to fix it?

If not, would it make sense to do some hackery like:

# debian/tests/control
Tests: manpage-references
Restrictions: superficial
Depends: libncurses-dev, ncurses-bin, ncurses-doc
Architecture: !i386

Tests: backspace-delete-keys, infocmp-dumb
Restrictions: superficial
Depends: ncurses-base, ncurses-bin
Architecture: !i386

Tests: manpage-references
Restrictions: superficial
Depends: libncurses-dev:i386, ncurses-bin:i386, ncurses-doc
Architecture: i386

Tests: backspace-delete-keys, infocmp-dumb
Restrictions: superficial
Depends: ncurses-base:i386, ncurses-bin:i386
Architecture: i386

Hopefully there's a better idea than this...?
