[Python-modules-team] Bug#841421: python-opcua: FTBFS (build hangs)

[Santiago Vila]

Package: src:python-opcua
Version: 0.10.17-3
Severity: serious

Dear maintainer:

I tried to build this package in stretch with "dpkg-buildpackage -A"
(which is what the "Arch: all" autobuilder would do to build it)
but it failed:

--------------------------------------------------------------------------------
[...]
 debian/rules build-indep
dh build-indep --buildsystem=pybuild --with python2,python3
   dh_testdir -i -O--buildsystem=pybuild
   dh_update_autotools_config -i -O--buildsystem=pybuild
   dh_auto_configure -i -O--buildsystem=pybuild

   dh_auto_build -i -O--buildsystem=pybuild
I: pybuild base:184: /usr/bin/python setup.py build 
running build

The relevant part of the build log is included above.

If this is really a bug in one of the build-depends, please use reassign and affects,
so that this is still visible in the page for this package.

If you could not reproduce this using sbuild on a single CPU virtual machine (as I did),
please do not downgrade or mark as unreproducible, I would then consider giving you access
to a virtual machine on which I can reproduce it so that you can as well.
(In such case, please contact me off-list for details).

Thanks.
