> Physical Address Extensions (PAE) 32-bit is available.
If the pae flag is not present in /proc/cpuinfo then PAE is not enabled
on your particular CPU, even if it is available for other CPUs in the
same family. The CPU indicates PAE support (or not) in the result of the
CPUID instruction, which i
I also ran into this problem with Xubuntu 16.04 LTS.
I'm running an Intel Pentium M 735, Dothan, (2MB L2 Cache, 1.70 GHz, 400 MHz
FSB) (CPUID: 6.D.6 (hex) or 06D6h or 6.13.6 (dec)).
When I lookup the specification on the Intel site, then it says:

FWIW - the rebooting part of comment #8 is essential.

Yes, it would be nice for the user to not have to bother with forcepae
to run computers with Pentium M and Celeron M CPUs.
But I think this is a great improvement. Forcepae (used according to
Colin Watson's advice in post #8) makes it much easier to use Ubuntu
flavours in version 14.04 LTS compare

How did you boot the installer? Normally syslinux will boot the kernel
in 16-bit mode and you would get the forcepae error message.

I'm not sure if a software fix is appropriate here. Should the ubiquity
installer do a special check to see if it's been s tarted with forcepae
and copy that option to the install regardless of what side of the '--'
the user put it on?
If not, then this really isn't a bug per se, as better documen
Comment to #11 : Actually the system works with or without the forcepae at boot
arguments. When option is removed from /etc/grup/default (and grub updated),
everything still works, but /proc/cpuinfo just does not show the pae over there.
System bootet without forcepae option:
foo@t42
I can confirm that Colin Watson's advice in post #8 works.

If the kernel is booted, then forcepae must have been supplied, and if
it is supplied then PAE should be flagged in cpuinfo. It looks like
this is only about copying forcepae across. See comment #8 for that.

so, the post-inst on the kernel checks to see that cpu does not have PAE and
then bails the upgrade.
However, it could check that even though cpu has no PAE support yet the
currently running kernel does have PAE config option enabled and continue with
the upgrade.

Just put the forcepae option after the "--" entry on the installer
