I have just downloaded snapshot 23388 (Nov 1st) and done a fresh install.
When I try to do apt-get upgrade I get :
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
I have tried updating /etc/apt/preferences from 600 to 500 as per http://forum.linuxmce.org/index.php?topic=10309.0
I have also tried changing apt-get to aptitude.
I have changed my sources.list from .archive & .security
When I try a different snapshot say Beta2 upgrades work fine.
Is anyone else having issues with 23388 snapshot? Or know what I am doing wrong.
