I've used the same rules for the same package the 30 January without problem.

Thanks for all advices

If you diff the working package against the broken one using debdiff on the two .dsc files, you'll find this among the output:

So you removed upstream code that forced "sh build.sh -i" to install under debian/python3-exiv2/, and so "sh build.sh -i" is now trying to install files directly into /usr rather than into the staging directory that's due to be packed up into the output .deb. Your job with your packager hat on is to figure out how to adapt your packaging for that change.

I don't think you have any way to fix this without patching configure.py. However, I wouldn't recommend just reverting to the previous code, as hardcoding debian/python3-exiv2 in upstream code was a layering violation. I would suggest changing the upstream configure.py to generate code in build.sh that honours the environment variable DESTDIR, prefixing its value to installation paths if it's set; you could then set that variable to debian/python3-exiv2 or similar in the override_dh_auto_install target in debian/rules.

(Alternatively, you could work out how to get a standard Python build system such as setuptools to do what you need rather than rolling your own build system, as they usually come with this sort of feature and are already well-integrated into Debian packaging tools.)

Ooops, I've used the bad config.py.

I'm the packager and the maintainer and this config.py is for my venv wher I work on my lib.

Now, with the good config.py the build was succeed.

Many thanks Colin.
