Issue Installing Picade X pHat

After running the one line installer I’m getting this.

Checking environment
Updating apt indices

Checking hardware requirements

Checking for packages required for GPIO control
raspi-gpio is already installed

Checking for dependencies
alsa-utils is already installed
lsb-release is already installed

Github repo already present. Updating
fatal: index file smaller than expected

Finalising Install

Picade is not showing up. I’m very new to all this. Any help please? Thanks in advance!
