How to Upgrade to Linux Kernel 4.1.1 on Ubuntu

Linux Kernel 4.1.1 was released earlier this week with a host of improvements and new features making it the most advanced and stable version of the 4.x LTS series.

Greg Kroah-Hartman, who released this latest version, recommended existing users of the 4.1 kernel series upgrade immediately. As the Linux Kernel 4.1.1 is an LTS version, every week a new version of Kernel 4.1.x will be released.
