Hi Samuel,

Thanks for the response.

Ack.

Ack, me too, except when it shows it's too sensitive. E.g. a lot of
python tests fail otherwise on deprecation warnings which is *not* what
we want in autopkgtests.

In most cases "please retry this with all to-be-migrated packages" can
be achieved by adding appropriate versioned breaks (for the breaking
package) or versioned (test) depends to the broken package. If people
find this unpretty, I don't mind scheduling the check for now. What Ivo
and I already have been considering, we should maybe accept the failure
*if* the current broken package passes in unstable. But I have to think
about what that means during transitions *before* the "broken package is
rebuild.

I'll make sure the package is tested with both packages from unstable,
to confirm that everything is OK.

Paul
