14 DAY TRIAL // Today, July 20, 2017, is the last day when the Ubuntu 16.10 (Yakkety Yak) was supported by Canonical as the operating system now reached end of life, and it will no longer receive security and software updates.
Dubbed by Canonical and Ubuntu founder Mark Shuttleworth as the Yakkety Yak, Ubuntu 16.10 was launched on October 13, 2016, and it was a short-lived release that only received nine (9) months of support through kernel updates, bug fixes, and security patches for various components.
"Ubuntu announced its 16.10 (Yakkety Yak) release almost 9 months ago, on October 13, 2016," said Adam Conrad. "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."
Users are urged to upgrade to Ubuntu 17.04 (Zesty Zapus) immediately
Starting today, you should no longer use Ubuntu 16.10 (Yakkety Yak) on your personal computer, even if it's up-to-date. Why? Because, in time, it will become vulnerable to all sort of attacks as Canonical won't provide security and kernel updates for this release.
Therefore, all users are urged to upgrade to Ubuntu 17.04 (Zesty Zapus) immediately using the instructions we've prepared below, or by accessing https://help.ubuntu.com/community/ZestyUpgrades. Ubuntu 17.04 is also a non-LTS release, but it will receive security and software updates until sometime in January 2018.
Upgrading Ubuntu 16.10 to Ubuntu 17.04
To upgrade Ubuntu 16.10 to Ubuntu 17.04, open the Software & Updates tool, go to the "Updates" tab, click on the "Notify me of a new Ubuntu version" drop-down menu and make sure the "For any new version" entry is highlighted. Open the Terminal app and copy/paste the "update-manager -c" (without quotes) command.
Hit Enter and the Update Manager tool should pop up to inform you that there's a new version of Ubuntu available, namely Ubuntu 17.04. All you have to do now is to click the "Upgrade" button and follow the instructions displayed on the screen to upgrade your Ubuntu 16.10 computer to Ubuntu 17.04.
If you're upgrading a server machine running Ubuntu 16.10, you should first install the "update-manager-core" package from the repositories, then set the prompt line in /etc/update-manager/release-upgrades to normal, and execute the "sudo do-release-upgrade" (without quotes) command to launch the upgrade tool, and follow the on-screen instructions.
