What version of Guile did you use?

Could you specify all commands that you used (after you had fetched the
tarball)?  So I could try to reproduce the problem.

Please attach logs in the future.  We shouldn't rely on third party
services.

Please send a message to bug-guile@gnu.org if you can't find anything
here [1].

I think that the above might cause some problems.  Normally, you don't
have to touch the store (i.e., '/nix/store') at all.  Could you specify
the absolute location of that Guile 2.0.9 directory?

Could you also try to install Guix from Git [2] and report any problems?

Finally, I hope that you'll switch to a free distro [3] instead of
Ubuntu that contains non-free [4] packages.
