[Bug 1046906] Re: Update Manager does not offer kernel updates

[sampo555]

Thank you for taking the time to report this bug and helping to make
Ubuntu better.

Ubuntu follows a slightly different versioning scheme than the upstream
Linux kernel. The version number of the upstream kernel increases with a
new stable release. However, when the Ubuntu kernel is updated to a new
stable release of upstream kernel, only upload number and possibly ABI
version is changed (see
https://wiki.ubuntu.com/Kernel/FAQ/GeneralVersionMeaning for more
details about Ubuntu kernel versioning).

If you wish to know, which upstream version the currently running kernel is based on, run
$ cat /proc/version_signature
Ubuntu 3.2.0-30.48-generic 3.2.27

The first field is always "Ubuntu", the second field is the Ubuntu
kernel version (3.2.0-30.48-generic), and the final field is the
upstream version (3.2.27).

You can also use the kernel version mapping (http://kernel.ubuntu.com
/~kernel-ppa/info/kernel-version-map.html) to convert a Ubuntu kernel
version to the corresponding upstream version. For example, your
3.2.0-29-generic maps to version 3.2.24 of the upstream kernel.

Title:
  Update Manager does not offer kernel updates

Status in “update-manager” package in Ubuntu:
  New

Bug description:
  I have upgraded from 12.04 LTS to 12.04.1 LTS using the updates
  provided by Update Manager:

  ~$ lsb_release -a
  No LSB modules are available.
  Distributor ID:	Ubuntu
  Description:	Ubuntu 12.04.1 LTS
  Release:	12.04
  Codename:	precise

  What is completey missing is the 3.2.14 kernel which was mentioned in
  the 12.04.1 release notes.

  ~$ uname -a
  Linux tuxdev64 3.2.0-29-generic #46-Ubuntu SMP Fri Jul 27 17:03:23 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

  Somehow I am still on 3.2.0 instead of 3.2.14

  Note:  I have scourred many forums looking for a solution for this to
  no avail.
