Ubuntu 16.10 Yakkety Yak

Canonical vient de lancer la version finale de la dernière évolution de sa distribution Linux Ubuntu. Estampillé Ubuntu 16.10 alias Yakkety Yak, ce système d’exploitation est proposé pour différents environnements allant du PC de bureau ou Cloud Computing en passant par les serveurs.

Ubuntu 16.10 alias Yakkety Yak, quoi de neuf ?

Ubuntu 16.10 est en développement depuis six mois maintenant. Son objectif est de proposer les derniers raffinements du monde GNU/Linux avec l’assurance d’une stabilité éprouvée.

Les utilisateurs ne doivent cependant pas s’attendre à une révolution. Cette nouvelle version se dévoile comme une évolution en douceur de cet OS open source. L’une des grandes nouveautés touche au moteur de la distribution avec l’adoption du noyau Linux 4.8. Cela permet d’améliorer la prise en charge du matériel récent. En parallèle plusieurs composants profitent de mises à jour basées principalement sur GNOME 3.20 Stack.

Il a cependant quelques applications pré-installées issues de GNOME 3.22 Stack. Ceci ne concerne pas le gestionnaire de fichiers Nautilus. La suite bureautique LibreOffice passe en version 5.2 tandis que le navigateur Firefox est en version 49.

Il y a la possibilité de découvrir le prochain environnement de bureau Unity 8. Il s’agit pour le moment que d’une découverte. Canonical le propose par défaut dans  le gestionnaire de connexion mais principalement à des fins de test. Il faut bien noter qu’Unity 8 peut rencontrer des problèmes selon la configuration matérielle présente.

Canonical souligne à son sujet

“Ubuntu 16.10 propose une prévisualisations de la vision de convergence de Canonical. Unity 8 Developer Preview inclut des applications qui « évoluent » du téléphone au bureau, de la souris à l’écran tactile »

 Les autres changements touchent à plusieurs autres choses. Par exemple Unity 7 profite d’une importante mise à jour censée améliorer les performances générales, le GPG binary est désormais basé sur GnuPG 2,  systemd est mis en œuvre dans les sessions utilisateurs tandis que la visualisation  des changelog pour l’AAE (Personal Archives Package) est de la partie.

Ubuntu 16.10 (Yakkety Yak) est pris  en charge durant neuf mois soit jusqu’en Juillet 2017. A cette date, la distribution ne profitera plus de mises à jour (logicielles et de sécurité).

Canonical propose différents ISO d’Ubuntu 16.10. Ils sont accessibles depuis le site officiel.

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.

qemu 2.6.1

Qemu has been updated to the 2.6.1 release.

See the Changelog for details. This already includes a stable releases, more about that can be found at 2.6.1 stable release.

Additionally this includes a backport to enable GPU Passthru for ppc64le.

DPDK 16.07

Ubuntu 16.10 includes the latest release of DPDK, 16.07.

See the Release Notes for details.

Noteworthy for DPDK application developers is that upstream deprecated the old mechanism of a combined shared library. libdpdk.so is now a linker script referring to the – individually packaged – sub-libraries librte-*. Furthermore the DPDK related kernel modules are now provided as dkms based packages.

libvirt 2.1

Libvirt has been updated to version 2.1. See the Changelogs for details.

In order to reduce the Debian delta, the main libvirt service has been renamed to libvirtd.service. libvirt-bin.service becomes an alias to maintain backwards compatibility.

Open vSwitch

Open vSwitch has been updated to the latest release, 2.6.

See the Open vSwitch News for mroe details.

The enablement of openvswitch-switch-dpdk has changed upstream. So if you are upgrading from a previously dpdk enabled configuration then you will need to update your enablement appropriately. See associated Readme at /usr/share/doc/openvswitch-switch-dpdk/README.Debian for details.

LXD 2.4.1

Ubuntu 16.10 ships with LXD 2.4.1. The main highlights for this new version of LXD are:

  • Support for AppArmor profile stacking. This allows containers to load their own AppArmor profiles, further securing tasks running inside LXD containers.
  • Building on the new AppArmor feature, it is now possible to install Snap packages inside LXD containers. For the time being, this is only possible with Ubuntu 16.10 containers that have the “squashfuse” package installed.
  • New network management features have been added to LXD, allowing the creation and management of bridges, DHCP settings, tunnels, … More information can be found from “lxc network help” and in the upstream documentation.

A full changelog can be found at: https://linuxcontainers.org/lxd/news/

LXD 2.4.1 can also be tried online at: https://linuxcontainers.org/lxd/try-it/

cloud-init

All of cloud-init’s recent development has been brought back to 16.04, so you’ve probably already used it in production! Some recent improvements include:

  • changes with systemd integration to better enforce order of boot which improve the reliability of configuring disks and network.
  • bug fixes
  • updated documentation on http://cloudinit.readthedocs.io
  • new format for configuring apt
  • support for configuring ntp

Known issues

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

  • Wifi shows no ap in oem end user mode, work around reboot the machine and then everything should work as expected (1633012)
  • Bluetooth driver on XPS13 9434 not functioning at all (1633019)

EC2

  • 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. (1616879)

PowerPC

  • Choosing an Entire Disk install on PowerPC will result in an un-bootable system. The work around is to manually partition your hard disk and create a 1GB ext2 /boot partition. One also needs to move /etc/yaboot.conf to /boot/etc/yaboot.conf and symlink it back. (1606089)

GCC

  • We have modified GCC to by-default compile programs with position independent executable support to improve the security benefits provided by

Address Space Layout Randomization.

  • This may cause difficulty when trying to compile Linux kernels that still need this patch applied.

Other programs may experience other problems; some debugging guidelines are at https://wiki.ubuntu.com/SecurityTeam/PIE

AppArmor

  • The Linux kernel recently changed how executables are run. AppArmor profiles that were developed on previous versions of the Linux kernel may require modification to allow the programs to work. Error messages will be logged (to dmesg or to auditd, if that is installed) that look like this:

… apparmor=”DENIED” operation=”file_mmap” … profile=”/usr/sbin/tcpdump” name=”/usr/sbin/tcpdump” … requested_mask=”m” denied_mask=”m” …

  • Often the profile and the name will match but this is not required.

The aa-logprof program from the apparmor-utils package can interactively prompt the user for previously-logged AppArmor messages. To run it, use sudo aa-logprof.

Desktop

  • 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.
  • Unity 8 session sometimes locks up when you press Print Screen (1525285)
  • Unity 8 session locks up when you press media meta keys such as play/pause. (1633046)
  • Unity 8 Web Browser has no sound. (1632620)

  1. La grande nouveauté d’Ubuntu 16, c’est sa facilité d’installation et d’utilisation. On insère le CD, on se laisse porter par l’installateur et une heure plus tard, tout fonctionne à merveille. Ceux qui ont connu les versions antérieures, se souviennent que ce n’était pas toujours le cas auparavant. Avec le virage Canonical, les “no-power users”, vous et moi quoi, peuvent enfin abandonner la firme de Redmond.

    1. Un grand bonjour a PIERRE LINUX 16 en effet s’installe facilement et fonctionne bien .et se dépanne normalement parfois sans etre specialiste. mais difficile de lire les dvd sur 16.10 amitiés a tous
