Yes, you are right. I found the keyfiles in the ~/.cache location,
thank you.

This machine is running GNU Guix on top of an old GNU/Linux-libre
distro (Trisquel7).

I edited the /etc/init/guix-daemon.conf configuration file and added
--substitute-urls=https://ci.guix.gnu.org to the exec line.

Then I used
 $ sudo -i
 # guix archive --authorize < path/to/ci.guix.gnu.org.pub
to authorize the server url.

But I think guix still tried to substitute from hydra.
So I deleted the rsa key entries in /etc/guix/acl manually and
performed a logout-login sequence to restart the daemon.

Now it works, hurray! I was able to perform a fast 'guix pull' (~2h)
and the space in / and /tmp turned out to be sufficient.

When invoking guix package -I for example, I encountered an error like
 guile: failed to install locale

But that went away after having updated and installed some packages.
Unfortunately, I don't know exactly which action was responsible to
make this message disappear.

Now that I am running an up-to-date version of guix, there seem to be
no further need to use --substitute-urls=https://ci.guix.gnu.org in the exec
line of the daemon config file nor to have the rsa key deleted in /etc/guix/acl.

I thank you all very much for your help. I feel pretty much relieved
and encouraged to keep trying guix.

best regards
Kai
