Re: Binary substituter

[Ludovic Courtès]

Having discussed it today, the problem seems to relate to the use of
Guile 2.0.5: the web client would not work as expected, and thus the
substituter would erroneously think that the queried store paths are
missing on hydra.gnu.org, and cache that.

I believe that commit 1c9e7d6 partly solves that.  That is, if you
‘rm -rf /nix/var/nix/substitute-binary/’, and then run
‘guix build hello -n’, it should report things that it would download.

However, if you type ‘guix build hello’, it will barf in ‘filtered-port’
when trying to actually download the thing.

If you run Guile 2.0.5, can you confirm that my predictions are correct?
:-)

(Again, there’s no problem with Guile > 2.0.5.)
