This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

If you remove existing PAE kernels it won't want to update them any more.... as you sow, so shall you reap, fortune favors the brave, etc. etc. :P – izx Jun 29 '12 at 16:24
@izx small correction to your comment . convert it to answer by adding extra text as " select to remove listed pae kernel in update manager from synaptic manager " bottom line is : " have to remove all existed PAE kernels and then upcoming PAE kernel which was listed in update manager " Thank you . – Raja Jun 29 '12 at 16:49

Why not remove the PAE kernels along with their headers? You don't use them anyway, and that will both solve the updates problem and free some space. To do that, use the following:

  1. This command will only show what's to be removed, without removing anything.

    dpkg -l linux-* | awk '/^ii/{ print $2}' | grep -v -e `uname -r | cut -f1,2 -d"-"` | grep -e [0-9] | xargs sudo apt-get --dry-run remove
  2. This command will purge all unused kernels and headers.

    dpkg -l linux-* | awk '/^ii/{ print $2}' | grep -v -e `uname -r | cut -f1,2 -d"-"` | grep -e [0-9] | xargs sudo apt-get -y purge

Info source

Edit: Apparently, that command doesn't remove the metapackages, so I'd add the follwoing as well:

sudo apt-get purge linux-generic-pae linux-image-generic-pae linux-headers-generic-pae
