N.Y.,

You may want to use the `--no-substitutes' option. Let us know how that works for you.

Yep, clearing the guix-daemon's substitute cache should workaround these

issues.

On my system, that can be done by running:

sudo rm -r /var/guix/substitute/cache/

I think the key bits here might be a duplicate of #63634

Looks like I need to upgrade my Guix system to fix substitution ... but 
"guix system build" is currently failing, which needs [cycle!].

This time when doing "guix system build" I have a new error:

I haven't seen this ‘failed to alternative substitute for [...]’ before 
and it seems unrelated to #63634. There is also bad error reporting 
here: failing to find a substitute is not a form of ‘corrupted/damaged 
input’.

I'll do the usual tricks (*) to work-around for now, to get the fix in 
#63634 even though it doesn't fix everything.

The one workaround I'd suggest is cleaning the guix-daemon's substitute
cache (/var/guix/substitute/cache). That alone should be sufficient to
work around any missing zstd nars.

I can't upgrade yet, because no substitute of webkitgtk is available:

The following derivations would be built:

At the end, I need to do:

./pre-inst-env guix build webkitgtk -S --no-substitutes

but I do not necessary want to rebuild all.

Well, all in all, I agree with Maxime that the backtrace is ugly, the

message misleading and last that various options should be tried

automatically (for fixed-outputs).

Cheers,

simon

Hi Chris,

I think this report is about two issues:

1. the substitute error,

2. the way the error is reported.

About #1, clearing the cache seems fixing.

About #2, an error about the substitutes server should not trigger “hard

to parse” backtrace or misleading hint, IMHO.

Cheers,

simon

I think I saw it again after upgrading but I might have misremembered.

IMO this manual action of having to clear the cache (in a new Guix) to 
work-around remainders of a bug in old guix should be unnecessary.

I consider having to do this a bug.

Also, I keep not receiving e-mails in my e-mail client.

Greetings,
Maxime.
