Hello Leo,
> I wonder what is going on? The current mutt package output is: --8<---------------cut here---------------start------------->8--- mathieu@meije ~$ guix build mutt --no-grafts /gnu/store/c0wp5iq5k11mvqrm4bs011qlm7qy48ia-mutt-2.0.7 --8<---------------cut here---------------end--------------->8--- The last mutt build on the master specification is https://ci.guix.gnu.org/build/321231/details, that reports the same output. This build has not been attempted again because its output didn't change. The substitute is however missing as you noticed. That's because the Cuirass GC root expired, and the nar file also probably expired its 90 days TTL. We should maybe increase this TTL, or make sure that every "latest" master derivation is covered by a GC root. WDYT? Thanks, Mathieu
