Hi, Matthieu Haefele <matthieu.haef...@cnrs.fr> skribis:
> Well, I installed guix on my laptop (with ubuntu) the very standard > way described on guix website. It was back in January 2020. OK. Lzip support was added sometime in 2019: <https://guix.gnu.org/en/blog/2019/substitutes-are-now-available-as-lzip/>. Could you try updating your daemon as described at: https://guix.gnu.org/manual/en/html_node/Upgrading-Guix.html Also, could you report the output of: /var/guix/profiles/per-user/root/current-guix/bin/guix-daemon --version before and after the upgrade? Thanks in advance, Ludo’.
