I’m trying to publish my first package and running into a problem. The publish succeeded and I can see my package on the hub and with `flox search` but I’m getting an error when installing. I’m attempting to install it on an `aarch64-linux` system (a Fedora VM running on macOS on an M2 macbook) but this is the error I get:

```auto
[lima@lima-flox-fresh newenv]$ flox install willgorman/fio@0.0.1
❌ ERROR: resolution failed: multiple resolution failures:

    but it is available for

It looks like this was a temporary issue, I can now install that version of the package successfully.

I did attempt to initially install the package while `flox publish` was still saying `Waiting for confirmation of successful publish…` because that step was taking a very long time and I could already see the package on flox hub so I thought I could try to install it. Maybe that cached something temporarily while the package wasn’t yet fully published?

Hi there! Yeah sounds like you tried to install it after we had the package metadata but we didn’t yet have the binaries ready for download. We could probably improve that error
