I try to make it clear what works and what does not work with Pentium M and Celeron M processors that have PAE capability but lack the PAE flag.

Title:
  No installable kernel was found in the defined APT sources

Status in linux package in Ubuntu:
  Invalid

Bug description:
  I tried to install from the Ubuntu Vivid 32-bit mini.iso into a
  computer with Pentium M

  http://www.cnet.com/laptops/lenovo-
  thinkpad-t42-2373/4507-3121_7-31155666.html

  and booted the installer with the forcepae boot option. This made the
  installer start and work until it should get the kernel. Then it
  stopped with the following message

  "No installable kernel was found in the defined APT sources ...
  Continue the installation without installing a kernel?"

  I checked if this is a PAE issue ... and yes, it is.

  Forcepae makes the installer work, but later on, during installation,
  it refuses to manage the [PAE] kernel. I tested, and it works in a
  computer with CPU with a built-in PAE flag. And the trusty mini.iso
  can install in the same computer with Pentium M, so this is a
  regression.

  At 'ctrl+alt+F4' it complains that the kernels found are not usable on
  486. But forcepae should allow it. And the same kernels work when
  installed with the corresponding daily Lubuntu Vivid desktop iso file.

  -o-

  This bug is reported from another computer, because I don't know how
  to report it from the mini.iso system. So you should disregard the
  collected data, that I might not be able to remove.
