I installed Ubuntu 14.04.1 LTS on machine and have upgraded its kernel version to 4.2 with the following command:

sudo apt-get install linux-generic-lts-wily

I was a bit confused about kernel version and release name. Some software provides binaries for different releases: Trusty, Utopic, Vivid, Wily, ...

In this case, should I download a binary for Trusty or that for a newer release name as far as the software provides?

Ubuntu releases and the kernel versions are independent from each other.

Open a terminal and check the Ubuntu release version with this command :

lsb_release -a  

The output shows something like :

No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 15.10
Release:    15.10
Codename:   wily

Open a terminal and check the running kernel version with this command :

uname -r  

The output shows something like :

4.2.0-22-generic  

This was a PC running Ubuntu 15.10 - here is a PC running Ubuntu 14.04 :
If you opt into the hardware enablement stack for Ubuntu 14.04 (Trusty),
the outputs will show that the release still is 14.04 and the kernel is 3.19.

lsb_release -a  

No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 14.04.3 LTS
Release:    14.04
Codename:   trusty  

uname -r  

3.19.0-42-generic

    For non-LTS releases kernel major versions are always same unless it is manually changed. For LTS it is quite different. – Pilot6 Dec 29 '15 at 15:03

Upgrading your LTS release to a newer kernel line does not change the release name.

So you still have Ubuntu 14.04 trusty.

See about HWE

LTS releases allow to install kernels from non-LTS main releases.

linux-generic-lts-wily installs the kernel from 15.10 "wily" release. It will be default in Ubuntu 14.04.4.

This may be a bit confusing.
