EDIT #1
Note that when:
sf package list --target-dev-hub bernardo@... I get:
Namespace Prefix Name Id Alias Description Type ──────────────── ──────── ────────────────── ──────── ─────────── ─────── R2C2_002 R2C2_002 0Hoxxxxxxxxxxxxxx R2C2_002 Managed Which means the package is alright. I don't know how to continue reviewing the status of the package or the reason it's unavailable. I think there should be a way to check the status or view a log or something.
