Comment 1 for bug 1537237

Hi Jeff,

The Trusty HWE (Hardware Enablement) kernels (aka linux-lts-trusty kernels) are the 14.04 LTS kernels made available in the 12.04 LTS updates and security archives, to give people who want to continue using Ubuntu 12.04 LTS access to kernels that would support hardware that become generally available after the 12.04 LTS release. Additionally, the Trusty HWE kernel is the default kernel installed from the 12.04.5 LTS point release install media.

https://wiki.ubuntu.com/Kernel/LTSEnablementStack describes it in more detail.

Thanks for the query, and I agree that it is a bit confusing and not as straightforward as it could be.
