Cydia won't update Intelliscreen

[prgeno]

Now that Rock is no longer, I tried using Cydia which says there is an update to the primary reason I have for jailbreaking, which is Intelliscreen.

The update is listed as 4.5.6 (I have 4.5.4 installed). I'm logged into Cydia via my Facebook login. Cydia says "Package Officially Purchased" so I assume my license have been successfully moved over from Rock.

However, whenever I try to download (it appears to download fine)and install the update it fails during installation. The errors that pop up are:
"Error:running subprocess /usr/bin/dpkg returned an error code (1)" with an "Okay" button.

After pressing "Okay" I get a series of errors all saying:
"/var/cache/apt/archives/firmware-sbin_0-1_iphoneosarm.deb subprocess pre-installation script returned error exit status 1" with an Okay button

After respringing, the Intelliscreen config app confirms the update did not install. I never had a problem updating Intelliscreen from within Rock.

Is this a Cydia problem, a Cydia/Rock acquisiton/conversion problem, or an update package problem?

I am running this on an iPhone 3G running 3.1.2 IOS.

Interesting, lots of Cydia/Rock talk but nobody even comments on this issue.

Am I the only one experiencing problems since the move from Rock to Cydia?

seems you have a corrupt apt list, nothing todo with the rock to cydia move.
this has just highlighted it.

Best bet is to using terminal try some APT codes such as 'apt-get' or google the rest to find the cleaning code
