I'm getting what appears to be exactly the same error as MrFlipnote.
First, some details of my system:
Hardware: Nexus 7 wi-fi only
Current Android version: 4.2.1
Current kernel version: 3.1.10-g22b4fcd
android-build@vpbs1.mtv.corp.google.com #1 Fri Nov 2 10:55:26 PDT 2012
Current build number: JOP40D
Locale: UK
Bootloader unlocked.
Rooted prior to this update.
ClockworkMod Recovery v.6.0.2.3.
SuperSU installed.
I first attempted to install the update after receiving the official notification that the update had been downloaded and was ready for installation: I clicked on the notification message, followed the prompts, and received the same error messages whose details I will give below.
Since then I have downloaded the update separately from -
http://android.clients.google.com/p....signed-nakasi-JDQ39-from-JOP40D.6ece895e.zip
- then attempted to invoke an update as follows:
On the (Ubuntu) PC, in a terminal:
1. [cd to the location of the downloaded zip.]
2. adb push 6ece895ecb23.signed-nakasi-JDQ39-from-JOP40D.6ece895e.zip /sdcard/
3. adb reboot recovery
That reboots the Nexus 7 to CWM Recovery mode. Then, on the Nexus 7:
1. Select menu option: Install zip from sdcard > Choose zip from sdcard.
2. Select folder "0", then scroll down to the pushed zip file and click it.
3. Click "Yes - Install 6ece[...].zip
Whereupon I get the errors listed below.
Things I've tried (followed by a repeat of the process above):
* In CWM, selecting option: Wipe cache parition.
* In CWM, selecting option: Advanced > Wipe dalvik cache.
* In CWM, selecting option: Fix permissions.
* In CWM, selecting option: Install zip from sdcard > Toggle signature verification.
None of those worked.
The error messages as reported on-screen on the tablet are as follows, when I attempt the update with signature verification switched off (with verification turned on, I also get the "signature verification failed" error reported by MrFlipnote):

Here is my full CWM log (obtained by selecting CWM menu option: Advanced > Report error, then finding the log on my tablet, in /data/media/clockworkmod/recovery.log), which contains some more detail:
