Updated Packages

Linux kernel 4.13

Ubuntu 17.10 is based on the Linux release series 4.13. It includes support for the new IBM z14 mainframe CPACF instructions and new KVM features.

Network configuration

ifupdown has been deprecated in favor of netplan and is no longer present on new installs. The installer will generate a configuration file for netplan in /etc/netplan, which will set up the system to configure the network via systemd-networkd or NetworkManager. Desktop users will see their system fully managed via NetworkManager as it has been the case in previous releases, but Server users now have their network devices managed via systemd-networkd on new installs. This only applies to new installations.

Given that ifupdown is no longer installed by default, its commands will not be present: ifup and ifdown are thus unavailable, replaced by ip link set $device up and ip link set $device down.

The networkctl command is also available for users to see a summary of the network devices. networkctl status will display the current global state of IP addresses on the system; and networkctl status $device can display the details specific to a network device.

For more information about netplan, please refer to the manual page using the man 5 netplan command.

Ubuntu Desktop

Ubuntu Server

qemu 2.10

Qemu has been updated to the 2.10 release.

Since the last version was 2.8 see both Changelogs of 2.9 and 2.10 for details.

Among many other changes there is one that might need follow on activity by the user/admin: Image locking is added and enabled by default. This generally makes execution much safer, but can break some old use cases that now explicitly have to opt-in to ignore/share the locks by tools and subcommands using the --force-share option or the share-rw dqev property.

libvirt 3.6

Libvirt has been updated to version 3.6. See the Changelogs for details.

LXD 2.18

LXD was updated to version 2.18.

Some of the top new features are:

See the Changelogs for details.

DPDK 17.05.2

Ubuntu 17.10 includes the latest release of DPDK that has stable updates: 17.05.2.

See the Release Notes as well as the stable release announcement stable .1 announcement stable .2 and for more detail.

This made it possible to integrate Open vSwitch 2.8.

Open vSwitch 2.8

Open vSwitch has been updated to 2.8.

Please read the release notes for more detail.

Remember that since version 2.7 you need to specify dpdk devices via dpdk-devargs.

New Bind9 KSK

The DNS server bind9 was updated to include the new Key Signing Key (KSK) that was published on July 11, 2017. Starting on October 11, 2017, that key will sign the root zone key, which in turn is used to sign the actual root zones. For more details, visit:

Existing installations of bind9 should automatically update their anchor keys following RFC 5011, but new installations after the rollover event on October 11th, 2017, will need this new package or have the key updated manually.

cloud-init

The version was updated to 17.1. Notable new features include:

curtin

The version was updated to 0.1.0~bzr519-0ubuntu1. Notable new features include:

Samba

Samba was updated to version 4.6.7.

Noteable changes in the 4.6.x series include:

The OS Version for the printing server has been increased to announce Windows Server 2003 R2 SP2 ID mapping checks added to the testparm(1) tool. There are some ID mapping backends which are not allowed to be used for the default backend. Winbind will no longer start if an invalid backend is configured as the default backend.
