Change kernel on Ubuntu Server 14.04.3

  • 772

How may i change kernel on headless Ubuntu Server 14.04.3 64bit ? I want to try some dailybuilt kernels because current one includes grsec patches which cause segfault problems. Or even same kernel without grsec.

The current one

Linux ovh-tb 3.14.32-xxxx-grs-ipv6-64 #1 SMP Sat Feb 7 11:35:27 CET 2015 x86_64 x86_64 x86_64 GNU/Linux
14.04

  1. I successfully did that procedure on production server. It is safe to update or change kernel by installing meta package:

    sudo apt-get install linux-generic-lts-vivid

    But then you need change grub entry to use new kernel, so check current menuentries issue:

    grep menuentry /boot/grub/grub.cfg

    Edit /etc/default/grub as root then update GRUB_DEFAULT to the corresponding menuentry number. Remember that entries started from "0"

    sudo update-grub
