[Message part 3 (text/plain, inline)]

After a recent guix pull, I'm getting tracebacks when attempting to run
guix challenge.

I tried switching subsititues to a local caching proxy, not sure if that
could possibly break anything. But after switching back to using the
substitutes directly, the problem still persists.

$ guix --version
guix (GNU guix) 1fa37d1b55b1d25a9d20c7b50a531b763e7a1398

$ guix challenge --substitute-urls="https://berlin.guixsd.org https://mirror.hydra.gnu.org" linux-libre

Hi,

ludo <at> gnu.org (Ludovic Courtès) skribis:

> This is due to an ABI breakage in the (web uri) module that Guile
> provides: in 2.2.3 ‘uri?’ is a procedure, but in 2.2.2 it’s a macro.
>
> As it turns out, build-aux/build-self.scm (which is what ‘guix pull’
> evaluates) selects the latest Guile 2.2.x, so it builds with 2.2.3, but
> then you run that code with 2.2.2, hence the error.

I’ve pushed a workaround as commit
66f217b43aca603326dab17d4dda1a398bf4fb8c.

Thanks,
Ludo’.
