Hey,
> Both tests fail with the strange message that the installer cannot access the > sdb2 partition where the guix installer is (see picture 3) Oh, I see. It should now be fixed with: e12be802e02b3345a753e7ec1287852a7337a0a5. It would be great if you could test this new installation image: https://ci.guix.gnu.org/download/357. Thanks for your patience, Mathieu
