<vgutierrez> I: dh_python3 pydist:220: Cannot find package that provides josepy. Please add package that provides it to Build-Depends or add "josepy python3-josepy" line to debian/py3dist-overrides or add proper dependency to Depends by hand and ignore this info.
didn't notice this before, also some previous packages I've built (on ubuntu bionic possibly with older debhelper versions) have come out with python3-josepy dependencies fine...
