insighttolkit4: remove everywhere except amd64 and i386

[Gianfranco Costamagna]

Insighttoolkit4 is a complex software, and upstream can't make it work on anything except amd64 and i386.
For such scientific software, disabling testsuite is a bad thing, because it results in a broken software, giving wrong results to the end user without noticing them.

Please kick arm64 armhf ppc64el and s390x out from the archive, including reverse-deps.

We should just sync the next release

[Matthias Klose (doko)]

why should we do this, is there any reference from upstream about this?

[Gianfranco Costamagna (costamagnagianfranco)]

yes, but I forgot where.

btw the analysis about what can go wrong if ITK misbehaves is done by an ex-colleague of mine, who used it in his tumor-related research university master thesis.

A wrong analysis can draw the user into the wrong conclusions, and the worst part is that different architecture might give different results.

unless somebody does a real porting, I would recommend to not ship that software at all where not supported.

Another prove is here:
https://launchpad.net/ubuntu/+source/camitk/4.1.2-2build1

camitk (a reverse-dependency) has now a testsuite that fails everywhere except amd64 and i386, and failing tests are related to itk bugs

rdeps are missing

[Gianfranco Costamagna (costamagnagianfranco)]

fw4spl should just be kicked out from release

[Steve Langasek (vorlon)]

I have reuploaded insighttoolkit4 to fail the build when the test suite builds (a precondition for this removal is that the binaries won't grow back on reupload) and it has now failed to build on all non-x86 architectures https://launchpad.net/ubuntu/+source/insighttoolkit4/4.12.2-dfsg1-4ubuntu7.

I have removed the binaries for all of these packages from the eoan release pocket on armhf,arm64,ppc64el,s390x. So this removal is done.

I agree that insighttoolkit4 should become a sync again in the next Debian upload. We should not be wasting (considerable) buildd time in Ubuntu only just to try and fail to build the package on architectures unsupported by Debian or upstream.
