If you installed it long ago, it could be that you authorized
substitutes from hydra.gnu.org (the former CI server, discontinued in
June¹) but not from ci.guix.gnu.org.

So you would need to check:

  1. which substitute URL guix-daemon is using;

  2. which keys are authorized in /etc/guix/acl.

The above chapter of the manual has more info on this.

LMK how it goes!

Guix needs space in /gnu/store to store the actual build results, and it
needs space in /tmp when it’s building stuff.

Building ‘tar’, for example, consumes quite a bit of space (in /tmp)
because its test suite runs on large files.

It depends on your use case of course, but most likely you’ll need at
least a dozen GiB.

But first, I recommend figuring out the substitute story so you don’t
have to build everything locally!

Thanks,
