Ubuntu 19.04 (Disco Dingo) released

Codenamed "Disco Dingo", 19.04 continues Ubuntu's proud tradition
of integrating the latest and greatest open source technologies into a
high-quality, easy-to-use Linux distribution. The team has been hard at
work through this cycle, introducing new features and fixing bugs.

The Ubuntu kernel has been updated to the 5.0 based Linux kernel,
our default toolchain has moved to gcc 8.3 with glibc 2.29, and we've
also updated to openssl 1.1.1b and gnutls 3.6.5 with TLS1.3 support.

Ubuntu Desktop 19.04 introduces GNOME 3.32 with increased performance,
smoother startup animations, quicker icon load times and reduced CPU+GPU
load. Fractional scaling for HiDPI screens is now available in Xorg
and Wayland.

Ubuntu Server 19.04 integrates recent innovations from key open
infrastructure projects like OpenStack Stein, Kubernetes, and Ceph with
advanced life-cycle management for multi-cloud and on-prem operations,
from bare metal, VMware and OpenStack to every major public cloud.

The newest Ubuntu Budgie, Kubuntu, Lubuntu, Ubuntu Kylin, Ubuntu MATE,
Ubuntu Studio, and Xubuntu are also being released today.

More details can be found for these at their individual release notes:

Maintenance updates will be provided for 9 months for all flavours
releasing with 19.04.

New team for Shibboleth package maintenance in Ubuntu

Hash: SHA512

Hello everyone,

In order to better coordinate maintenance of Shibboleth-related
packages [1] in Ubuntu, I created a new team "pkg-shibboleth" on
Launchpad [2] and invite everyone interested to join it. I see this
team as a kind of equivalent to the Debian Shibboleth packaging team.
In the same move, I would like to use the Git repositories on [3] to maintain Shibboleth packages for Ubuntu (under
the ubuntu/ namespace as per DEP-14 [4]) and keep them as identical as
possible to the Debian packages (like they are now). With common
packaging repositories, security fixes should also be easier to
coordinate (cherry-picking patches, for example).

One of my goals with this initiative is to provide backports of the
latest Shibboleth version for Ubuntu LTS releases through official
channels (i.e. <lts>-backports). I've been doing backports for Debian
since 2016 both in the official archive and with a private repository
[5] with help from the Debian Maintainer (thanks Ferenc!) and
Shibboleth developers (thanks Scott!), on time and resources provided
by my employer (SWITCH). SWITCH's private repository [5] is intended
for Shibboleth users in Switzerland, but in practice it has gained a
world-wide audience. By using official Ubuntu channels, I want to make
those packages available to every Ubuntu user without configuring a
third-party repository, as is already the case with Debian. Also this
opens the door to collective maintenance at a central place instead of
pushing other interested developers into operating their own
repository in case they want to release faster than I do or support
older LTS releases.

I hope this team gathers enough interest to build a sustainable group
of maintainers. I also warmly welcome guidance from experienced Ubuntu
developers, being quite new to Ubuntu-specific processes and tools.


[1] source packages: log4shib, opensaml, shibboleth-resolver,
shibboleth-sp, xml-security-c, xmltooling

post-disco software-properties port to PackageKit ready for testing

Hi folks,

I just finished porting disco's software-properties to PackageKit,
so we have less aptdaemon around. Target here is early ee, as disco
is about to release, so for now I put a build into the PPA at:

If you have some time to spare, possibly after the release is done,
give it a go and leave me some feedback. Interested whether driver
installation and cache refresh after editing sources works for you,
in both GTK+ and Qt frontends; and also how DebConf works for you.

We might be switching to a new apt daemon[1] in the future, as PackageKit
is not really actively developed, and lacks features needed for update-manager
(and well, synaptic, for those who want synaptic on wayland, but that's
not _really_ the main focus) but it's at least one aptdaemon tool less.

I also plan to be uploading that to Debian experimental later on, so
we get some feedback there hopefully; although, they are in a freze
as well, so ....

Release Candidate (and testable!) Disco Dingo builds ready to test (hint hint!)



Disco Final builds should now be available on the ISO QA tracker[1].
These builds are not final. We're still waiting on a few more fixes, a
few things to migrate, etc. Neither base-files or the ISO labels are
updated yet, so please don't file bugs about those.

What there are, however, are "close enough" for people to be testing in
anger, filing bugs, fixing bugs, iterating image builds, and testing all
over again. So, please, don't wait until Wednesday night to test,
testing just before release is *TOO* *LATE* to get anything fixed. Get
out there, grab your favorite ISO (if you don't have a favorite, grab
them all), beat it up, find bugs, report bugs, escalate bugs, fix bugs,
respin (if you're a flavor lead with access), and test, test... And
test. Did I mention testing? Please[2] test.

[2] Please. Pretty please?

Disco Dingo (19.04) Final Freeze - is it available?


Are the above isos available for testing yet - and where are they? Was hoping to test it this morning but I haven't heard a peep so far.
