Step 1 :
Go to the following link and get your access key.
Get Ksplice Uptrack Access Key
Step 2 :
Add the following lines to the file ksplice.list.
deb http://www.ksplice.com/apt natty ksplice
deb-src http://www.ksplice.com/apt natty ksplice
Step 3 :
Replace INSERT_ACCESS_KEY with your access key. Please use the same
access key for all of your systems:
sudo apt-get install ca-certificates
wget -N https://www.ksplice.com/apt/ksplice-archive.asc
sudo apt-key add ksplice-archive.asc
echo 'uptrack uptrack/accesskey string INSERT_ACCESS_KEY' | sudo debconf-set-selections
sudo apt-get update
sudo apt-get install uptrack
Step 4 :
Change the following as is :
autoinstall = yes
Step 5 :
Ksplice Uptrack updates your running kernel in memory only. Enabling
autoinstalldoes not mean the Uptrack client itself is automatically upgraded. You will be notified via e-mail when a new Uptrack client is available, and it can be upgraded through your package manager.
That's all! See you.
