Discussed on #guix [0]:

[14:40:28] <civodul> hmm /gnu/store/njdhsdv216hyk23nfrc7wh9hbq17ymxk-compute-guix-derivation has no references
[15:49:47] <civodul> if i rebuild compute-guix-derivation.drv locally, it gets a proper list of referenecs
[15:52:40] <lfam> civodul: How do you figure out which drv it is?
[15:52:52] <civodul> "guix gc --derivers ...-compute-guix-derivation"

Ludo rebuilt the affected file on berlin.guixsd.org, so you garbage
collect 'njdhsdv216hyk23nfrc7wh9hbq17ymxk-compute-guix-derivation' and
then try again.

If that doesn't work yet, rebuild one of the derivers locally with
--no-substitutes.
