Unfortunately i’m not able to join the beta 2 party bus.
The official upgrade path ends with the terminal commands for replacing the two repositories (the »out of memory« error again).
I was able to boot my usb stick (in safe-mode), but the installer isn’t working. I’ve tried different destinations, it’s reporting »bad data« everytime right after hitting the install button.
Booting from my beta 1 partition and trying that installer was failing too: »Permission denied«?
