Ah. In that case it's a `know bug' that is being worked on. > how do I do that? I looked into core-updates-next and at the moment it does not seem to be in a really usable state, in other words: work in progress. Theoretically one might do `guix pull --branch=<branch-name>'. However, branches other than master and version-1.0.x are generally not suited for general use. See `14.6 Submitting Patches' (https://guix.gnu.org/manual/en/html_node/Submitting-Patches.html). Using a developer branch like core-updates-next is usually done by working on a clone of the Guix Git archive. See `14.1 Building from Git' (https://guix.gnu.org/manual/en/html_node/Building-from-Git.html).
