Hi Guys,
I have a Ubuntu 9.04 Linux running on Freescale's i.MX515(ARM Cortex based) board with me.

There were about 250 updates pending and I did that today, well towards the end I could see that some of the updates failed because of the infamous errors:

E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.
E: Couldn't rebuild package cache
E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.

If I do a 'sudo dpkg --configure -a' I get more errors, like -

What do I do now? Any solutions?

Is your disk full?

Dear AlucardZero, Thanks for your reply.

From the Nautilus I see that there is still 856.6 MB free on the SDCARD of the board (I'm using a 4GB SDCARD with Ubuntu image on it).

In the current state, when I do sudo apt-get none of them complete. All of them end with E: dpkg was interrupted,.....

One thing I have noticed, during the booting. I see a list of -
mmcblk0: error -110 transferring data
end_request: I/O error, dev mmcblk0, sector 32
Buffer I/O error on device mmcblk0, logical block 4

But I'm not quite sure if these were also occurring before I did the 256 updates.

Also, the update manager still pops up with the following (Important Security)updates:

libavcodec52 (4MB)
libavformat52 (652KB)
libavutil (97KB)
libpostproc(82KB)
libswscale0(148KB)

There it is, I have mentioned very close-to status of my system.
