Hi @ollieglass! Hm. It looks like there might be a missing s on what should be curl -sSL, but I just tried both commands and didn’t see an issue on my machine. Let me ask some other folks on our end to see if we can re-create and file a bug if so.
If you’re on Astronomer Cloud right now, you’ll want to be on CLI v0.7.5-2 (otherwise you’ll get this incompatibility error). You’ll be able to upgrade CLI versions as soon as we upgrade our Cloud cluster (soon!).
In the meantime, run the following:
curl -sSL https://install.astronomer.io | sudo bash -s -- v0.7.5-2
