12.04 - Dist upgrade to fix dirty c0w vulnerability does not work - Ask Ubuntu


today decided follow steps patch server dirty c0w vulnerability.

it's running ubuntu 12.04 lts:

uname -rv 3.2.0-87-generic #125-ubuntu smp fri jun 19 08:25:10 utc 2015 uname -a linux webdev 3.2.0-87-generic #125-ubuntu smp fri jun 19 08:25:10 utc 2015 x86_64 x86_64 x86_64 gnu/linux

so, every version prior 3.2.0-113.155 affected, i've ran following command:

sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade

everything went fine, rebooted:

sudo reboot

but check version, has not changed:

uname -rv 3.2.0-87-generic #125-ubuntu smp fri jun 19 08:25:10 utc 2015

did miss ? double checked , didn't error during during upgrade.

edit based on comments / answers

i ran sudo update-grub , got following:

generating grub.cfg ... warning: setting grub_timeout non-zero value when grub_hidden_timeout set no longer supported. found linux image: /boot/vmlinuz-3.2.0-87-generic found initrd image: /boot/initrd.img-3.2.0-87-generic found linux image: /boot/vmlinuz-3.2.0-86-generic found initrd image: /boot/initrd.img-3.2.0-86-generic found linux image: /boot/vmlinuz-3.2.0-85-generic found initrd image: /boot/initrd.img-3.2.0-85-generic found linux image: /boot/vmlinuz-3.2.0-84-generic found initrd image: /boot/initrd.img-3.2.0-84-generic found linux image: /boot/vmlinuz-3.2.0-83-generic found initrd image: /boot/initrd.img-3.2.0-83-generic found linux image: /boot/vmlinuz-3.2.0-82-generic found initrd image: /boot/initrd.img-3.2.0-82-generic found linux image: /boot/vmlinuz-3.2.0-80-generic found initrd image: /boot/initrd.img-3.2.0-80-generic found linux image: /boot/vmlinuz-3.2.0-79-generic found initrd image: /boot/initrd.img-3.2.0-79-generic found linux image: /boot/vmlinuz-2.6.32-38-server found initrd image: /boot/initrd.img-2.6.32-38-server found memtest86+ image: /memtest86+.bin done

after reboot still no change.

ran dpkg --get-selections | grep linux , got:

seems there no new linux images in list.

however, when ran sudo apt-cache policy linux-image-generic listed new version candidate (it's in french it):

linux-image-generic:   installé : (aucun)   candidat : 3.2.0.113.129  table de version :      3.2.0.113.129 0         500 http://fr.archive.ubuntu.com/ubuntu/ precise-updates/main amd64 packages         500 http://security.ubuntu.com/ubuntu/ precise-security/main amd64 packages      3.2.0.23.25 0         500 http://fr.archive.ubuntu.com/ubuntu/ precise/main amd64 packages

ok managed upgrade.

here's how did it.

based on ron comment on answer decided run:

sudo apt-get install linux-image-generic

that failed because of /boot being full got rid of old versions running:

sudo dpkg -r linux-image-3.2.0-79-generic sudo dpkg -r linux-image-3.2.0-80-generic sudo dpkg -r linux-image-3.2.0-82-generic sudo dpkg -r linux-image-3.2.0-84-generic sudo dpkg -r linux-image-3.2.0-85-generic

after ran:

sudo apt-get upgrade -f

then reboot:

sudo reboot

and now, i'm running "safe" version:

uname -rv 3.2.0-113-generic #155-ubuntu smp tue oct 18 17:53:59 utc 2016

however, still have no idea why running following never worked:

sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade
