10/26/2026, 8:39 AMmise has the same issue as it also uses the aqua backend which is baked into mise. We'll need to wait for mise to cut a new release so that it has the registry fix. Until then, installing any version above 1.233.0 with mise fails.
A work-around is to MISE_AQUA_BAKED_REGISTRY=false which will make mise fetch the latest aqua registry π.Erik Osterman (Cloud Posse)
