I'm having problems with running Guix on top of openSUSE. I installed
clean 0.12 release on clean system.

$ guix pull

This shows 2 problems:

- pull doesn't support `--fallback'
- hydra build of apr-util is probably corrupted


When I try to help manually, it sometimes helps...

 $ guix build apr-util --fallback
The following derivation will be built:

...and sometimes it gives me different hash...

$ guix build python <at> 2.7.10 --fallback

/gnu/store/813i9qr3l6w5ada97l1m1cna08fzrra9-python-2.7.10-tk

...and pull will never work.


Is there anything I could do to workaround the problem?

and `--substitute-urls` is missing there as well...

sorry, it should be probably python-2.7.10

Let us know if it works and be sure to remove that URL afterwards; that
server cannot handle much traffic.

Thanks, I solved it some other way in the meantime. But thanks, this
could work as well...

From single user perspective it is valid workaround but I'm aftraid
that from guix package maintainer on foreign distribution it is not
usable workaround...

Best regards,

Sure, and we know that `guix pull` needs to be overhauled. We've been
discussing its shortcomings and designing the replacement:
