Hi Gabriel, Just like packages can depend on other packages, so Guix channels can depend on other channels. A channel can define dependencies in the .guix-channel file at the root of each repository. Checking through each channel, I found that guix-gaming-games depends on guix-past. As for getting around it, you could try running "guix pull --roll-back" and try pulling again. Hope that helps, James
