Ooh, there=E2=80=99s a bug here.  The URL should be:

  https://mirror.hydra.gnu.org/file/linux-libre-4.4.18-gnu.tar.xz/sha256/0k=
8k17in7dkjd9d8zg3i8l1ax466dba6bxw28flxizzyq8znljps

(Compare the part right after =E2=80=9C/file.=E2=80=9D)

I believe this is fixed by 328f7cbe435d79d61f57129d9e3ee90404d6bfda.

Now, you can either build and install guix-daemon from =E2=80=98master=E2=
=80=99, or
simply make sure to do:

  export NIX_STORE=3D/home/royadav/opt/guix/local/gnu/store

in the environment where guix-daemon runs.

If you=E2=80=99re using systemd, I guess you can add this setting in the un=
it
file.

Once you=E2=80=99ve done that, you should be able to download this tarball =
from
mirror.hydra.gnu.org transparently.

HTH!

Ludo=E2=80=99.
