Hi, and thanks for the report.

That one should be simple enough: since yubikey-manager/2.0.0-2,
I use a Build-Depends on debhelper-compat to control the dh compatibility level.

The version of dh in stretch is too old for this, and sbuild calls the clean
pass outside the schroot; pass --no-clean-source to sbuild (or specify it in
your configuration) if you expect to build packages from sid on a host running
stable.

Could you confirm that the package builds correctly, without patching,
if you pass --no-clean-source ?

OK, I'll try passing --locale=C.UTF-8 (what does `locale` output, in your
environment?) and check this doesn't break anything under sbuild or debuild.

I'd prefer not to rollback the debhelper compatibility level to 10;
however, I'll happily commit the locale-related changes and credit you.


Best,
