如果你需要把Ubuntu 16.04升级成Ubuntu 16.10版本，请按下面的方法进行。（官方提供的方法）
To upgrade on a desktop system:
Open the "Software & Updates" Setting in System Settings.
Select the 3rd Tab called "Updates".
Set the "Notify me of a new Ubuntu version" dropdown menu to "For any new version".
Press Alt+F2 and type in "update-manager -d" (without the quotes) into the command box.
Update Manager should open up and tell you: New distribution release '16.10' is available.
Click Upgrade and follow the on-screen instructions.
To upgrade on a server system:
Install the update-manager-core package if it is not already installed.
Make sure the /etc/update-manager/release-upgrades is set to normal.
Launch the upgrade tool with the command sudo do-release-upgrade -d.
Follow the on-screen instructions.
Note that the server upgrade will use GNU screen and automatically re-attach in case of dropped connection problems.
There are no offline upgrade options for Ubuntu Desktop and Ubuntu Server. Please ensure you have network connectivity to one of the official mirrors or to a locally accessible mirror and follow the instructions above.
注：Ubuntu 16.10搭载Linux kernel 4.8内核，支持更多的硬件设备。
