[Bug 1160346] Re: do-release-upgrade upgrade from Precise fails : This kernel does not support a non-PAE CPU.

[Chris Bainbridge]

For anyone who thinks this isn't a problem for normal users:

"I mistakenly upgraded to 12.10 in my t42 without realizing the pae/non-
pae kernel conflict. now my system is kind of broken. i can not install
you .dep package because the package manager breaks when loading.
anything i do with apt-get update etc give me 'this kernel does not
support non-pae' errors." -

"This worked perfectly for me on an old Toshiba with a Pentium M
processor. I had also mistakenly upgraded to 12.10 before installing the
fake-pae package." -

Title:
  do-release-upgrade upgrade from Precise fails : This kernel does not
  support a non-PAE CPU.

Status in “update-manager” package in Ubuntu:
  New

Bug description:
  Attempting to upgrade from Precise with a non-PAE kernel will result
  in a failed upgrade. do-release-upgrade should check whether the user
  is using a non-PAE kernel and refuse to run, rather than upgrading to
  a broken system with no installed kernel.

  After downloading 1.5GB+ of data and over 1000 new packages, the
  upgrade will eventually report failure. Looking through the logs there
  is no kernel installed because of the error "This kernel does not
  support a non-PAE CPU.":
