Re: Guix can't find substitutes, even though guix weather claims they exist

[Timo Wilken]

Hi,

I've just run into this problem again... I ran guix pull, then guix
home reconfigure two minutes ago. This time aerc and hledger are
rebuilt from scratch, even though guix weather claims substitutes
exist for both (both on bordeaux; only aerc on ci.guix.gnu.org).
