Hi Luis, After confirming that the service works fine in ‘guix system vm’, I figured this must be a state problem.
The solution turned out to be simple: --8<---------------cut here---------------start------------->8--- ludo@bayfront ~$ sudo rm -rf /var/lib/guix-packages-website/.cache/guile/ccache ludo@bayfront ~$ sudo herd restart guix-packages-website Service guix-packages-website is not running. Service user-homes has been started. Service guix-packages-website has been started. --8<---------------cut here---------------end--------------->8--- 👉 https://packages.guix.gnu.org/ IWBN to pre-compile everything instead of letting auto-compilation do it, with this kind of problems coming up. Apologies for the delay! Ludo’. PS: Instead of delegating each request to the Data Service, I think guix-packages-website should simply maintain a local database with all the relevant info, similar to what <https://git.sr.ht/~whereiseveryone/toys> does (a separate Shepherd service populates a sqlite database) or <https://github.com/UMCUGenetics/hpcguix-web> (all the data is kept in a JSON file periodically updated by time machine).
