Update: Last Linux kernel did not install correctly (was: Re: Problems with Apper / automatic upgrading of my Debian 7.11 system)

[rhkramer@gmail.com]

Ok, I now believe that my problem is that the last Linux image (kernel) update 
did not install correctly / completely.  That image was "linux-image-3.2.0-4-
amd64 Linux 3.2 for 64-bit PCs"

I believe that what has been happening since then is that, each time I've 
installed something else (either recommended by apper to keep the system up-
to-date or as a new program I wanted) both the intended program and the Linux 
image attempted to install, and, typically, the intended program was installed 
or updated successfully, but the Linux image was not.

I can't absolutely confirm that for every case before a few days ago, but, in 
the updates or installs I've done since then, I've noticed that the popup 
message that says there was a problem occurs while apper is attempting to 
install the new kernel.  (To clarify--since that attempt about two weeks ago 
to install the kernel, every subsequent attempt to install anything has caused 
that message to popup, but, before a few days ago, I hadn't noticed that apper 
was re-attempting to install the Linux image).

Aside: apper has installed several linux images before this one, and I never 
had this problem before, and typically did not reboot soon after the update--
instead, I waited until there was some other reason to reboot.

So, now what do I do?

Per the warning from Johann Klemmer, I want to be careful about rebooting--I 
don't want to attempt a reboot that might fail.

Is there any log of the apper install process that would give me more 
information than the popup messages:

<quote>
Package failed to install - Apper

One of the selected packages failed to install correctly.
More information is available in the detailed report.

And, upon clicking on Details, I get the following:

<quote>
subprocess installed post-installation script returned error exit status 1
</quote>

Other suggestions?

Thanks,
Randy Kramer

Aside: I suppose this might be considered somewhat rude, but I wrote the above 
with a headache, my glasses off, and only a cursory attempt at proofreading--I 
apologize!
