Hi Denis, Thanks for your answer.
Strange thing, though… I didn't received your answer!? I came across it by chance while checking [bug-guix](https://lists.gnu.org/archive/html/bug-guix). > Sat, 12 Nov 2022 16:40:20 +0100 > Does it also fails with 'guix pull -M 1 -c 1' ? Thanks for the tip, but unfortunately, I get the same kind of error: ``` building /gnu/store/sq3w2hk9z1va6q2dbjg16mi0afw64q9b-gnutls-3.7.7.drv... substitute: updating substitutes from 'https://ci.guix.gnu.org'... 100.0% substitute: updating substitutes from 'https://ci.guix.gnu.org'... 100.0% substitute: updating substitutes from 'https://ci.guix.gnu.org'... 100.0% substitute: updating substitutes from 'https://ci.guix.gnu.org'... 100.0% substitute: updating substitutes from 'https://ci.guix.gnu.org'... 100.0% substitute: updating substitutes from 'https://ci.guix.gnu.org'... 100.0% substitute: updating substitutes from 'https://ci.guix.gnu.org'... 100.0% substitute: updating substitutes from 'https://ci.guix.gnu.org'... 100.0% substitute: updating substitutes from 'https://ci.guix.gnu.org'... 100.0% \ 'build' phas\Backtrace: 15 (primitive-load "/gnu/store/62r09kg575mg293by6fb83808p9diy3b-compute-guix-derivation") In ice-9/eval.scm: 155:9 14 (_ _) 159:9 13|(_ #(#(#(#(#(#(#(#(#(#(#(#(#(#(#(#(#<directory (guile-u?> ?) ?) ?) ?) ?) ?) ?) ?) ?) ?) ?) ?) ?) ?) ?) ?))
