Hi Etienne,

Sorry for the delayed reply, I've been either busy or on holiday, and
this won't change much for the rest of this summer.

I'm not sure how long wheezy-backports(-sloppy) will stay open.  By
https://backports.debian.org/news/stretch-backports/ I'd expect it to
close soon, because wheezy supported by LTS only...  Maybe worth asking
the LTS team.

Did you also find the cause of the failure?  I've got negligible
experience with piuparts.

Well, direct upgrades from wheezy to stretch are not supported, but from
wheezy to wheezy-backports-sloppy... er, I don't know.  But it would be
nice, if feasible.

You certainly have to revert 4a20cce3 to enable direct upgrades from
< 2.5.3+dfsg, so this is a good move.  Could you please send me the full
piuparts logs of the failing scenario with this change included?

20863ed8 is another revert candidate for wheezy, by the way.
