Christoph Thiede uploaded a new version of Installer-Core to project The Trunk: http://source.squeak.org/trunk/Installer-Core-ct.447.mcz
==================== Summary ====================
Name: Installer-Core-ct.447 Author: ct Time: 30 May 2022, 8:29:16.661662 pm UUID: de20d79f-7397-a243-ab5a-a4712e237212 Ancestors: Installer-Core-cmm.446
Enables new bootstrapping process for Metacello and fixes dependencyWarning for Squeak 6.0beta.
With the new process, the first installation of Metacello does not require us to load an auxiliary gemsource package any longer, but we use a pre-generated SAR file instead that is hosted on files.squeak.org [2,3].
With this change, the dependency on the gemsource repository is eliminated. Additionally, the SAR includes a recent fix for Metacello which removes the dependency on BlockContext from the 60Deprecated package. [3] Last but not least, this improves the installation time signifcantly - on my machine, [Metacello new] timeToRun decreases from 119 seconds to 50 seconds.

Thanks to Tom (tobe) for designing and pushing this new process!
Revision to installation script: Handle networking errors gracefully.
