Looking through the syslog further, I see the following message, which occurs during the disk detection phase of the installer: > parted_devices: /lib/libblkid.so.1: version `BLKID_2.17' not found (required by /lib/libparted.so.0) I think this may be related to http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=587570
