bug#54447: cuirass: missing derivation error

[Ludovic Courtès]

Mathieu Othacehe <othacehe@gnu.org> skribis:

> A lot of builds, among them ~20 system tests[1], are failing with:
> "cannot build missing derivation
> ?/gnu/store/hs6kp1lqgymhyp3jndc0dsp0pn4psgv0-gui-installed-desktop-os-encrypted.drv?"
> errors.
>
> Those derivations are present on the CI head node. This means that the
> errors occur during substitution. This is most likely caused by some
> issue with the publish server, because:
>
> - The publish server serves a 404 error. We should get rid once and for
>   all of this 404 thing, pushing something like:
>   https://issues.guix.gnu.org/50040.
>
> or
>
> - The publish server is not fast enough and hits an Nginx timeout that
>   closes the communication.
