Update-manager is hung bringing my 12.04 up to the 3.2.0-40 kernel. The cancel button is greyed out. Is it safe and adequate to click the x icon? If not, what sequence to kill the hierarchy of processes, as listed below.

The window says: Applying changes Configuring linux-image-3.2.0-40-generic-pae

Details window:

Setting up linux-image-3.2.0-40-generic-pae (3.2.0-40.64) ...

Running depmod.

update-initramfs: deferring update (hook will be called later)

Examining /etc/kernel/postinst.d.

run-parts: executing /etc/kernel/postinst.d/apt-auto-removal 3.2.0-40-generic-pae /boot/vmlinuz-3.2.0-40-generic-pae

run-parts: executing /etc/kernel/postinst.d/dkms 3.2.0-40-generic-pae /boot/vmlinuz-3.2.0-40-generic-pae

The process hierarchy is:

How long have you waited ? Best to let it run. –  bodhi.zazen Apr 9 '13 at 17:05
    
It's been about 90 minutes. new kernel levels, including the grub cycles for generic then generic-pae usually take maybe a minute after download. –  user15972 Apr 9 '13 at 17:38
    
You can try to kill the process or reboot (choose an old kernel). After you do, open a terminal and manually run sudo apt-get upgrade, see what if any errors you get. –  bodhi.zazen Apr 9 '13 at 18:02
    
Thank you. I (1) killed the processes. (2) sudo apt-get upgrade (3) Synaptic package manager reinstall of the 3.2.0-40 items (4) shutdown & reboot with 3.2.0-40 All's well. –  user15972 Apr 9 '13 at 19:14
