Comment 29 for bug 1160346

Folks,

At the risk of sounding in inappropriately (again), I wanted to
reiterate that the bug report I filed was when I tried to update my
Pentium M ThinkPad from Ubuntu 12.04 to 12.04.3 / 12.04.4.

http://askubuntu.com/questions/336527/how-to-upgrade-ubuntu-12-04-2-12-04-3-to-12-04-4-the-next-hardware-enablement/417581#417581

http://www.omgubuntu.co.uk/2014/02/ubuntu-12-04-4-released-new-kernel

http://www.ubuntuask.com/q/answers-why-12-04-2-to-12-04-3-didnt-upgrade-kernel-3-5-3-8-and-or-xorg-368181.html

That was where I created unmet dependencies and hosed my upgrade
manager until I undid via the Synaptic Package Manager.

Neither in the read me nor on any of the above pages did I understand
that I should not do such an upgrade on a notebook with non-PAE
processor. Also, as I was trying to perform the update, I did not get
an error message until the upgrade was partially complete.

Will the work done help people like me, those with a non-PAE processor
who try to upgrade to a more current version of the 12.04 LTS?

Again, I want to repeat how much respect and appreciation I have for
the work you folks do.
