Hello
Following the Metacello installation instructions [1] the following step A runs fine but the step B afterwards gives an error message 'File too short' [2], marked with '"ERROR FILE TOO SHORT'
"A: Get the Metacello configuration (for Squeak users)" Installer gemsource project: 'metacello'; addPackage: 'ConfigurationOfMetacello'; install.
"B: Bootstrap Metacello Preview, using mcz files (#'previewBootstrap' symbolic version" ((Smalltalk at: #ConfigurationOfMetacello) project version: #'previewBootstrap') load.
Any suggestion how to fix this?
Kind regards Hannes

Please make sure to clean your package cache, maybe an mcz got corrupted earlier during download. (I just recently fixed some things in the workflow)
