Reading package lists: Error!
E: Encounter a section with no package :Header

I dont know what is the problem plz help me

My experience with apt-get update ; apt-get upgrade is generally poor if you’ve not been keeping up to date nearly continuously.

I’d suggest getting another 8GB micro-SD card and installing the latest image from beagleboard.org, or one of Robert’s testing images: http://elinux.org/Beagleboard:BeagleBoneBlack_Debian
