Adam Conrad has sent out a reminder to people running Ubuntu 16.10 (code name "Yakkety Yak") that this version of Ubuntu is nearing the end of its supported life. People currently running Ubuntu 16.10 may wish to upgrade to version 17.04 or switch to a long term support (LTS) release such as Ubuntu 16.04. "Ubuntu announced its 16.10 (Yakkety Yak) release almost 9 months ago, on October 13, 2016. As a non-LTS release, 16.10 has a 9-month support cycle and, as such, the support period is now nearing its end and Ubuntu 16.10 will reach end of life on Thursday, July 20th. At that time, Ubuntu Security Notices will no longer include information or updated packages for Ubuntu 16.10. The supported upgrade path from Ubuntu 16.10 is via Ubuntu 17.04." Upgrade instructions can be found on this Ubuntu community help page.
