Hi Guix, There is a build failure with biber 2.12 in current Guix (commit 7b40d59114e1462d6d8140f325a66b12e91db667). The build log is attached, it shows that several tests fail.
Note that I tried to update to biber 2.13, which builds without problems, but I then discovered that it is not compatible with the texlive version we currently have. Cheers, Konrad.
