I am running Ubuntu 12.04.1 LTS i686 on VirtulBox. Every time I check the updates, there's a new Linux kernel. If I install the new kernel, I have to install the Virtulbox Guest Additions again and reboot the server. I don't want to do this every week. I know I can manually uncheck the kernel packages from update manager, but is there a way to skip the kernel update automatically? I found an answer here, but it's for Ubuntu 10. Thanks.
APT (Advanced Packaging Tool) is the system that Ubuntu uses to manage all of the software installed on a system. It allows you to “pin” a package to a certain version, so that it won’t be updated when you the Update Manager runs.
To pin your kernel packages, first you must determine what version your kernel is. One way to do this is to open the Synaptic Package Manager in System > Administration.
Type in “linux-generic” in the Quick search text field and hit enter.
Make a note of the number listed in the “Installed Version” column. We’ll use it in the next step.
Next, we need to edit the file /etc/apt/preferences. Open it by pressing Alt+F2 to bring up the Run Application window and entering in:
This will open up a gedit window. Most likely the window will be blank, unless you’ve played around with APT before.
In the window, type in the following, replacing the version number with the version number you found in the Synaptic Package Manager.
Save the file and close gedit. If you open the Update Manager, you should see that the Linux kernel updates are now hidden!
Blocking packages with APT/DPKG
Remember the package name of your kernel from above.
Open a terminal and run:
And hit enter.
Enter your password for sudo:
To remove pin from Apt/Dpkg:
Open a terminal
Replace kernel_package with the package you want to pin.
What you're trying to do is called pining. The sources i gave you above, have the essentials on what you must do to accomplish your tasks in hand.
