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.

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.
New features in 16.10
Linux kernel 4.8
Ubuntu 16.10 is based on the Linux release series 4.8.
The gpg binary is now provided by gnupg2.
Update Manager now shows changelog entries for PPAs too (253119).
Apps provided by GNOME have been updated to at least 3.20. Many apps have been updated to 3.22 also.
systemd is now used for user sessions. System sessions had already been provided by systemd in previous Ubuntu releases.
As is to be expected, with any release, there are some significant known bugs that users may run into with this release of Ubuntu 16.10. The ones we know about at this point (and some of the workarounds), are documented here so you don't need to spend time reporting these bugs again:
Boot, installation and post-install
Booting the CD on UEFI hardware may fail to complete, only showing a blank screen. This is caused by an issue with the UEFI Shim and has been reported to fail on ThinkPad laptops as well as in QEMU virtual machines. Other devices may also be affected. This issue is expected to be resolved for the final release. (1624096)
Some EC2 instance types are not currently booting, due to changes in the way that ext4 filesystems are created in yakkety. All instance types are expected to boot by release. See https://bugs.launchpad.net/cloud-images/+bug/1616879 for details.
- GTK+ 3.20 requires theme developers to make changes to their themes. Many (but not all) popular themes are now compatible with GTK+ 3.20.
It is not possible to add an account in Online Accounts (1613670).
