package linux-image-4.2.0-22-generic (not installed) failed to install/upgrade: subprocess new pre-installation script returned error exit status 1

[Derek Roberts]

This machine (I believe) has PAE capabilities (Pentium-M), but 15.10 has become very unforgiving of machines that don't report PAE flags in /proc/cpuinfo.
I had a royal pain in the behind upgrading from 15.04 (where --forcepae just did the business) to 15.10 because this package wouldn't install and only managed to retrive a completely stuffed machine by hacking /proc/cpuinfo to force the PAE flag on there. This is of course temporary.

It would be useful if whoever maintains the code that does /proc/cpuinfo would recognize the exception created by Intel with not correctly reporting PAE and fix this flag if future Ubuntu releases are going to barf so badly on not seeing it.

Working around the problem for now with this:

     cat /proc/cpuinfo | sed 's/flags\t*:/& pae/' > /tmp/cpuinfo_pae
      sudo mount -o bind /tmp/cpuinfo_pae /proc/cpuinfo
      sudo mount -o remount,ro,bind /proc/cpuinfo

But would like a more permanent solution

"But would like a more permanent solution" - I agree with that!
I upgrade XUbuntu 14.10 to 15.10 and then software update kernel 4.2.0-25-generic and then I got same error.

The problem solved as Derek wrote, but what about next update?
