Upgrading from Ubuntu 14.04 LTS or 15.10
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' if you are using 15.10, set it to 'long-term support versions' if you are using 14.04 LTS.
- Press Alt+F2 and type in 'update-manager' (without the quotes) into the command box.
- Software Updater should open up and tell you: New distribution release '16.04 LTS' 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 if you are using 15.10, lts if you are using 14.04 LTS.
Launch the upgrade tool with the command sudo do-release-upgrade.
- 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.
Snap application format
Ubuntu 16.04 LTS introduces a new application format, the ‘snap’, which can be installed alongside traditional deb packages. These two packaging formats live quite comfortably next to one another and enable Ubuntu to maintain its existing processes for development and updates. More information is available here.
Updated Packages
As with every new release, packages--applications and software of all kinds--are being updated at a rapid pace. Many of these packages came from an automatic sync from Debian's unstable branch; others have been explicitly pulled in for Ubuntu 16.04.
For a list of all packages being accepted for Ubuntu 16.04, please subscribe to xenial-changes.
Linux kernel 4.4
Ubuntu 16.04 LTS is based on the long-term supported Linux release series 4.4.
Python 3
Python2 is not installed anymore by default on the server, cloud and the touch images, long live Python3! Python3 itself has been upgraded to the 3.5 series.
If you have your own programs based on Python 2, fear not! Python 2 will continue to be available (as the python package) for the foreseeable future. However, to best support future versions of Ubuntu you should consider porting your code to Python 3. Python/3 has some advice and resources on this.
VIM defaults to python3
The default VIM package has been built against python3 instead of python2. This means plugins that require a python2 interpreter support from VIM will not work anymore. For this case alternative VIM packages are available that still use python2, for example vim-gnome-py2. They can be made the default via the alternatives mechanism:
sudo update-alternatives --set vim /usr/bin/vim.gnome-py2
Golang 1.6
The golang toolchain was upgraded to the 1.6 series, and gccgo was upgraded to the GCC 6.1 release candidate 1. Thus the same level of standard library and compiler features are provided by both compilers on all fully supported architectures.
OpenSSH 7.2p2
Recent OpenSSH releases disable several pieces of weak, legacy, and/or unsafe cryptography. If you are upgrading a system remotely over SSH, you should check that you are not relying on these to ensure that you will retain access after the upgrade.
Support for the legacy SSH version 1 protocol is disabled by default at compile time. Note that this also means that the Cipher keyword in ssh_config(5) is effectively no longer usable; use Ciphers instead for protocol 2. The openssh-client-ssh1 package includes 'ssh1', 'scp1', and 'ssh-keygen1' binaries which you can use if you have no alternative way to connect to an outdated SSH1-only server; please contact the server administrator or system vendor in such cases and ask them to upgrade.
Support for the 1024-bit diffie-hellman-group1-sha1 key exchange is disabled by default at run-time. It may be re-enabled using the upstream instructions.
Support for ssh-dss, ssh-dss-cert-* host and user keys is disabled by default at run-time. These may be re-enabled using the upstream instructions.
Support for the legacy v00 cert format has been removed.
Several ciphers are disabled by default in ssh: blowfish-cbc, cast128-cbc, all arcfour variants and the rijndael-cbc aliases for AES.
MD5-based and truncated HMAC algorithms are disabled by default in ssh.
GNU toolchain
glibc was updated to the 2.23 release, binutils to the 2.26 release, and GCC to a recent snapshot from the GCC 5 branch (post GCC 5.3.0).
Apt 1.2
Apt 1.2 includes the new privilege separation features introduced in Apt 1.1. Importantly, the unprivileged '_apt' user is now used when making outgoing network connections and parsing the results for the various apt transport methods (HTTP, HTTPS, FTP).
Ubuntu for IBM LinuxONE and z Systems
Ubuntu 16.04 LTS includes a new port to 64-bit z/Architecture for IBM mainframe computers. This is a practically complete port of Ubuntu Server and Cloud with around 95% binary package availability. We are excited to enable OpenStack software, Juju, MAAS, LXD, and much more on this platform.
For more information about this port see S390X page.
Ubuntu Desktop

Ubuntu Server
General
New in 16.04, the kernel crash dump mechanism now supports remote kernel crash dumps. It is now possible to send kernel crash dumps to a remote server using the SSH or NFS protocols. Details of the new functionality are available in the Ubuntu Server Guide.
Since the release of 16.04.2, the server ISOs are now larger than a standard 700MB CD. The increase in size is due to the ability to run the installer with the use of the Hardware Enablement (HWE) kernel. The HWE kernels enables newer platforms and components, which require functionality delivered in newer kernels, while allowing the continued use of an LTS release.
OpenStack Mitaka
Ubuntu 16.04 includes the latest OpenStack release, Mitaka, including the following components:
OpenStack Identity - Keystone
OpenStack Imaging - Glance
OpenStack Block Storage - Cinder
OpenStack Compute - Nova
OpenStack Networking - Neutron
OpenStack Telemetry - Ceilometer and Aodh
OpenStack Orchestration - Heat
OpenStack Dashboard - Horizon
OpenStack Object Storage - Swift
OpenStack Database as a Service - Trove
OpenStack DNS - Designate
OpenStack Bare-metal - Ironic
OpenStack Filesystem - Manila
OpenStack Key Manager - Barbican
Please refer to the OpenStack Mitaka release notes for full details of this release of OpenStack.
OpenStack Mitaka is also provided via the Ubuntu Cloud Archive for OpenStack Mitaka for Ubuntu 14.04 LTS users.
Ubuntu 16.04 also includes the first GA release of of the Nova driver for LXD ('nova-lxd').
WARNING: Upgrading an OpenStack deployment is a non-trivial process and care should be taken to plan and test upgrade procedures which will be specific to each OpenStack deployment.
Make sure you read the OpenStack Charm Release Notes for more information about how to deploy Ubuntu OpenStack using Juju.
libvirt 1.3.1
Libvirt has been updated to the 1.3.1 release.
qemu 2.5
Qemu has been updated to the 2.5 release.
See http://wiki.qemu.org/ChangeLog/2.5 for details.
Open vSwitch 2.5.0
Ubuntu 16.04 includes the latest release of Open vSwitch, 2.5.0. This is also an LTS release of Open vSwitch.
Ubuntu 16.04 also includes support for Open vSwitch integrated with DPDK (Data Plane Development Kit) enabling fast packet processing through userspace usage of compatible networking cards - see the openvswitch-switch-dpdk package for more details.
Ceph Jewel
Ubuntu 16.04 includes the latest release candidate (10.1.2) of the Ceph Jewel stable release; An update to the final release version will be delivered as an SRU to Ubuntu 16.04.
For full details on the Ceph Jewel release, please refer to the upstream release notes.
Nginx
Ubuntu 16.04 includes version 1.9.15 of the Nginx web server, with an expectation to provide the next stable release of Nginx, 1.10.0, as an SRU after release (which will be virtually identical to 1.9.15). This version of Nginx also includes HTTP/2 support, which supersedes SPDY support previously provided in the Nginx packages.
LXD 2.0
Ubuntu 16.04 LTS includes LXD, a new, lightweight, network-aware, container manager offering a VM-like experience built on top of Linux containers.
LXD comes pre-installed with all Ubuntu 16.04 server installations, including cloud images and can easily be installed on the Desktop version too. It can be used standalone through its simple command line client, through Juju to deploy your charms inside containers or with OpenStack for large scale deployments.
All the LXC components - LXC, LXCFS and LXD - are at version 2.0 in Ubuntu 16.04 LTS.
Learn more about LXD here: http://www.ubuntu.com/cloud/lxd/
And discover all the LXD 2.0 features with: https://www.stgraber.org/2016/03/11/lxd-2-0-blog-post-series-012/
docker 1.10
docker was upgraded to version 1.10. Note that this requires migration of existing images to a new format which will be performed on the first start of the service. This migration can take a long time and put a high load on the system; see https://docs.docker.com/engine/migration/ for more information.
PHP 7.0
PHP was upgraded to 7.0. Note that this will require modifications to custom PHP extensions (https://wiki.php.net/phpng-upgrading) and may require modifications to PHP source code (http://php.net/manual/en/migration70.php).
- NGINX and PHP 7.0
Upgrading from a prior version of Ubuntu with PHP5 FPM configurations and NGINX will require a manual configuration change (details at: http://dark-net.net/nginx-http2-php7.0).
Most PHP-dependent packages were either rebuilt or upgraded for PHP7.0 support. Where that was not possible, packages may have been removed from the archive. There was one exception, Drupal7.
Drupal7 did not pass upstream testing with PHP7.0 as of the 16.04 release (https://www.drupal.org/node/2656548) and therefore the Ubuntu package was uninstallable. Before Ubuntu 16.04.2, Drupal7 was updated and is now installable (1582340).
MySQL 5.7
MySQL has been updated to 5.7. Some configuration directives have been changed or deprecated, so if you are upgrading from a previously customized configuration then you will need to update your customization appropriately. See bug 1571865 for details.
Password behavior when the MySQL root password is empty has changed. Packaging now enables socket authentication when the MySQL root password is empty. This means that a non-root user can't log in as the MySQL root user with an empty password. For details, see the NEWS file.
Juju 2.0
Juju and Juju UI have been updated to 2.0beta4. The final Juju 2.0 release will come via an update post-release. The package name is juju-2.0. Juju 1.25.5 is available in the juju package for existing production environments. Please read the upgrade documentation before moving to 2.0.
Juju now supports modeling workloads on AWS, Microsoft Azure, Google Cloud Engine, Rackspace, Joyent, LXD, MAAS, and manual deployments.
The Juju Charm Store now has over 300 charms ready to deploy. Most of these workloads will deploy Trusty instances, but we expect 16.04 charms to start landing and being announced independent of Juju's release.
Juju Core Release Notes
Juju GUI Release Notes
As is to be expected, with any release, there are some significant known bugs that users may run into with this release of Ubuntu 16.04. 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
Installing Xen host in UEFI mode
It is currently impossible to boot a Xen hypervisor from grub in UEFI mode. However the package does not detect this and will set the default boot to Xen mode. So for any machine in UEFI mode, do not install the Xen hypervisor (or enable legacy mode first). Please see this bug report for more information.
Upgrade
Kubuntu
WARNING: LTS to LTS upgrade to Xerus is currently problematic and should not be attempted. Please install a fresh copy of 16.04 instead. To prevent messages about upgrading, change Prompt=lts to Prompt=normal or Prompt=never in the /etc/update-manager/release-upgrades file.
OpenSSH
The default of the 'UseDNS' configuration option has changed from yes to no. This may cause users who use the 'from=' functionality in authorized_keys to limit ssh access by host to be locked out, which is especially troublesome if upgrading remotely. See bug 1588457.
MySQL
Users with customised MySQL server configurations may hit a maintainer script error on upgrade due to changed configuration directives in MySQL 5.7. This will need to be fixed up manually. See the general MySQL update notes for details and instructions on fixing one common case of this.
IBM LinuxONE and z Systems specific known issues
Fully automated preseed install
Fully automated preseed installation is currently not possible with only DASD drives at the moment. For zfcp installation s390-zfcp/zfcp preseed key can be used. For more information please see bug and bug.
zfcpdump not available yet
zfcpdump kernel is not available yet, and will be made available as an SRU at a later date. Please see this bug for more information.
Install-time parameters are not propagated to the installed system
If installation is performed with special kernel parameters, e.g. cio_ignore, these are not propagated to the installed system. Please edit /etc/zipl.conf to apply these and re-run sudo zipl to update the IPL. Please see this bug for more information.
IPv6 with PCI/RoCE
The Linux kernel has an issue in its IPv6 stack with PCI/RoCE cards. IPv4 with PCI/RoCE cards is fully supported. The Linux kernel needs an upgrade to the first SRU kernel post-release for complete IPv6 PCI/RoCE support. Please see this bug for more information.
SCSI LUN detection issues
Usage of SCSI LUNs on a DS8870 Storage server with μCode Bundles 87.51.xx.0 (LMC 7.7.51.xx) via NPIV enabled zfcp adaptors causes detection issues. Please see this bug for more information.
z/EDC compression cards
There is a known issue with z/EDC compression cards. Please see this bug for more information.
IBM POWER
PCI pass-through with QEMU-KVM
Running PCI pass-through with Ubuntu 16.04 kernel 4.4 and stock QEMU packages will lead to DI issues as soon as I/O starts on the pass-through adapter bug. In such a case an update to a QEMU packages with DDW support is required. Such packages are available via the following PPA: https://launchpad.net/~ibmpackages/+archive/ubuntu/ddw
CPU Hotplug with QEMU-KVM
CPU hotplug on ppc64el was not yet supported with the QEMU and Libvirt versions available in Ubuntu 16.04. If required please consider upgrading to 18.04 (Bionic).
Desktop
Unity 7
Sometimes Gtk application menus go missing https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1532226. You can workaround this by launching this from a terminal or Alt+F2 dash view:
restart unity-panel-service
Ubuntu Software
Ubuntu Mate Docker Windows 10
Sometimes doesn't update apps to 'Installed' after installation via search https://bugs.launchpad.net/ubuntu/+source/gnome-software/+bug/1551599
Does some time-consuming operations without any indicator https://bugs.launchpad.net/ubuntu/+source/gnome-software/+bug/1572606
Missing some details for apps that aren't installed https://bugs.launchpad.net/ubuntu/+source/gnome-software/+bug/1564621https://bugs.launchpad.net/ubuntu/+source/gnome-software/+bug/1571414

Review stars aren't clickable https://bugs.launchpad.net/ubuntu/+source/gnome-software/+bug/1549555
Doesn't use full deb descriptions or translations https://bugs.launchpad.net/ubuntu/+source/gnome-software/+bug/1559338
- Upgrades from previous versions can result in two Software Center icons in the launcher. One for the old Ubuntu Software Center and one for the new Ubuntu Software application. The Ubuntu Software Center icon can be removed if required.
Server
HTTP/2 support in Apache httpd
HTTP/2 support is considered an experimental feature by the Apache httpd upstream project, and so we do not consider it suitable or maintainable for the 5 year supported period of this LTS release. Therefore HTTP/2 support is not available in our builds of Apache httpd.
We expect to issue stable release updates enabling HTTP/2 support after the Apache httpd upstream considers this support to be non-experimental, although this will depend on our assessment of the risk of regression to existing Xenial users at that time.
Graphics and Display
fglrx
The fglrx driver is now deprecated in 16.04, and we recommend its open source alternatives (radeon and amdgpu). AMD put a lot of work into the drivers, and we backported kernel code from Linux 4.5 to provide a better experience.
When upgrading to Ubuntu 16.04 from a previous release, both the fglrx driver and the xorg.conf will be removed, so that the system is set to use either the amdgpu driver or the radeon driver (depending on the available hardware).
More information is available at https://tjaalton.wordpress.com/2016/03/11/no-catalystfglrx-video-driver-in-ubuntu-16-04/
6th gen Intel Core CPUs and llvmpipe software rasterizer
LLVM-3.8 enables AVX512 on all 6th generation Intel Core CPUs ('Skylake') when it should be enabled only on server CPU's. This causes the user session to fail to start when Mesa llvmpipe driver is used. This should happen only when the system has a separate GPU which isn't natively supported by open source drivers.
This bug will be handled in a post-release update. In order to install a machine suffering from this remember to boot directly to the installer instead of live-session which doesn't start, and select the option to 'Download updates while installing' to make sure updated packages are installed before logging in for the first time. https://bugs.launchpad.net/ubuntu/+source/llvm-toolchain-3.8/+bug/1564156
