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.
https:/
~$ 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.

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/GeneralVers ionMeaning for more details about Ubuntu kernel versioning).
If you wish to know, which upstream version the currently running kernel is based on, run signature
$ cat /proc/version_
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.
