Hi Guix,

yesterday I installed a new Guix System (on iron) using the installer
(latest stable
https://ftp.gnu.org/gnu/guix/guix-system-install-1.1.0.x86_64-linux.iso.xz
on USB)

The installation is fine but when I try to guix pull I get this:

I searched in the current guix master branch and found icu4c is at
version 66.1 now (the commit that upgraded to 64.2 is 27ed6960be)

The problem is that
http://download.icu-project.org/files/icu4c/64.2/icu4c-64_2-src.tgz
moved pernamently:

--8<---------------cut here---------------start------------->8---

This will be a build server so I'm not using substitutes:

--8<---------------cut here---------------start------------->8---

   (guix-service-type config =>
                                (guix-configuration
                                 (inherit config)
                                 (use-substitutes? #f)
                                 (authorized-keys
                                  %authorized-guix-keys))

--8<---------------cut here---------------end--------------->8---

Please how can I fix this situation?

Thanks! Gio'
