8. If fetched `version` > local `version`, `umbrel-manager` checks if local `version` satisfies the `requires` condition in the fetched `info.json`.
9. If not, umbrel-manager makes a `GET` request to `https://raw.githubusercontent.com/getumbrel/umbrel/vX.Y.Z/info.json` and repeats step 8 and 9 until local `version` < fetched `version` and local `version` doesn't fulfill the fetched `requires` condition.
9. If not, `umbrel-manager` computes the minimum satisfactory version, called `L.M.N`, required for update. Eg, for `"requires": ">=1.2.2"` the minimum satisfactory version would be `1.2.2`. `umbrel-manager` then makes a `GET` request to `https://raw.githubusercontent.com/getumbrel/umbrel/vL.M.N/info.json` and repeats step 8 and 9 until local `version` < fetched `version` **AND** local `version` doesn't fulfill the fetched `requires` condition.
10. `umbrel-manager` then returns the satisfactory `info.json` to `umbrel-dashboard`.
