Hi, 

when trying to install fdroidserver, I have the following build failure
in the tests with python-networkx:

I've the following setup:

Host distribution: Parabola i686 with an x86_64 kernel (linux-libre-64)
Guix: Guix i686

Do I need to give more information?

Denis.

I can reproduce on i686 (--system=i686-linux) but not x86_64.
The test failure appears to be determenistic but architecture-dependent.

Greetings,
Maxime.

Can you `guix pull` and test it again? I just updated it to 2.6.2 and
building with --system=i686-linux didn't show me any test errors.

I tried to build fdroidserver again after doing 'guix pull' and this
time it worked fine.

Thanks a lot.

Denis.

You can close the issue by sending a mail to <49913-done@debbugs.gnu.org>.

Closing.
