How to Install Linux Kernel 4.7 in Ubuntu 16.04/14.04

Linux Kernel

Linus Torvalds finally announced the release of the Linux Kernel 4.7. He wrote on lkml.org:

So, after a slight delay due to my travels, I’m back, and 4.7 is out.

Despite it being two weeks since rc7, the final patch wasn’t all that big, and much of it is trivial one- and few-liners. There’s a couple of network drivers that got a bit more loving. Appended is the shortlog since rc7 for people who care: it’s fairly spread out, with networking and some intel Kabylake GPU fixes being the most noticeable ones. But there’s random small noise spread all over.

Kernel 4.7 release highlights:

  • open source support for Radeon RX 480 GPUs
  • async discard support by the core block code
  • support for upgrading firmware using the EFI Capsule
  • New Linux Security Module (LSM) “LoadPin”
  • support for generating virtual USB Device Controllers in USB/IP
  • numerous drivers updates and lots of bug-fixes.
