Ubuntu – Will “apt-get upgrade” update the kernel on LTS

12.04updates

I am using Ubuntu 12.04 LTS. My question is: Will running "apt-get upgrade" update the kernel? I have read in some untrusted places that only running "apt-get dist-upgrade" will update the kernel.

Is it true?

P.S.Logically I don't think it should update, as it is LTS (stable release).

Only those installing from the 12.04.2 or newer point release media will automatically receive a newer enablement stack by default.

To remain on the original Precise stack, Install from a previous 12.04.0 or 12.04.1 point release and update. The previous 12.04.0 and 12.04.1 releases are archived here.

Ubuntu – How to update kernel to the latest mainline version without any Distro-upgrade

The simplest set of instructions I always used for kernel upgrade / downgrade are by ubuntuforums.org user by the name of lykwydchykyn (url modified by me for this post):

Go here: http://kernel.ubuntu.com/~kernel-ppa/mainline/

Download 3 (maybe 4) debs to a folder somewhere:

linux-headers-VERSION-NUMBER_all.deb
linux-headers-VERSION-NUMBER_amd64.deb
linux-image-VERSION-NUMBER_amd64.deb
linux-image-extra-VERSION-NUMBER_amd64.deb   # if available

Install the debs with whatever package manager front-end you use (is gdebi still around?), or use these commands:
```
cd /path/to/folder/where/you/put/the/debs
sudo dpkg -i *.deb
```

Ubuntu – apt-get dist-upgrade doesn’t fix ‘The following packages have been kept back’

That means they've been kept back for a more difficult reason than new dependencies or needing the removal of other packages. Try apt-get install libavdevice53, which will try a bit harder to upgrade that package. You may find that it wants to remove something you don't want removed.
