can anybody plz help me
PS yesterday i tried to install headphone daemon & media box, both were downloaded but app manager encountered an error in nistalling both. since then its giving me this error.

at a short glance it looks like your filesystem got corrupted somehow.
/var/lib/dpkg/status is a plain text file and if the app manager can't read it, it probably means the fs has issues.

the most easy and safe way would be, imo, reflashing the rootfs (where /var/ lives).


edit: i don't think it makes a difference, but check if that file /var/lib/dpkg/status exists at all.

looks like your software index is broken or corrupted.
There should be a backup of same file status-old. try to move that status-old to status and try again.
I hope they are not much difference between them and might work
As root
-- First copy the main file
# cp -p /var/lib/dpkg/status /var/lib/dpkg/status.orig
# cp -p /var/lib/dpkg/status-old /var/lib/dpkg/status
# apt-get update

why it show
archives directory /var/cache/apt/archives/partial is missing
what i have to do?

recreate.
- get root
- do
mkdir /var/cache/apt/archives/partial

i try mkdir /var/cache/apt/archives/partial
but it show
cannot create directory /var/cache/apt/archives/partial : No such file or directory

please, post the results of

ls -alR /var/cache/
