The Ubuntu team is very pleased to announce our seventh long-term support
release, Ubuntu 18.04 LTS for Desktop, Server, Cloud, and Core.

Codenamed "Bionic Beaver", 18.04 LTS 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 4.15 based Linux kernel,
with additional support for Linux security module stacking, signing
of POWER host and NV kernels, and improved support for IBM and Intel
hardware enablement from Linux 4.16.

Ubuntu Desktop 18.04 LTS brings a fresh look with the GNOME desktop 
environment.  GNOME Shell on Ubuntu is designed to be easy to use for
people upgrading from 16.04 LTS and presents a familiar user interface.
New features for users upgrading from 16.04 LTS include assistance with
logging in to public Wifi hotspots and the Night Light feature to
reduce eye strain in the evenings.

18.04 LTS also brings the new minimal installation option which provides
a full desktop with only the essential packages installed, and a tool to
easily enable Canonical LivePatch to apply critical kernel security fixes
without rebooting.

Ubuntu Server 18.04 LTS includes the Queens release of OpenStack
including the clustering enabled LXD 3.0, new network configuration via
netplan.io, and a next-generation fast server installer.  Ubuntu Server
brings major updates to industry standard packages available on private
clouds, public clouds, containers or bare metal in your datacentre.

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:

    https://wiki.ubuntu.com/BionicBeaver/ReleaseNotes#Officia...

Maintenance updates will be provided for 5 years for Ubuntu Desktop,
Ubuntu Server, Ubuntu Cloud, and Ubuntu Core. Ubuntu Studio will be
supported for 9 months. All the remaining flavours will be supported
for 3 years.

Still no coherent SSL trust though? That's a shame, as it's been basically a solved problem for a number of years now and it just needs the distribution to care.

Could you elaborate, please, on what you mean? Is there a comparison available to illustrate the better way? Thanks.

I'm actually happy that my browser's certificate store and the system one are distinct.

It turns out I have to trust way more CAs to surf web conveniently than I need for everything else.

You can always add CAs to your browser's certificate store, even once this is fixed. You don't have to add them to the system store if you don't want to.

These are about 150 root certificates and are enabled by default.
In the lifetime of the distro installation, probably only a fraction of those will ever get used.
Ideally, there should be an accounting tool to keep track when those root certificates are being used and for what websites.

Back to your report at Launchpad, https://bugs.launchpad.net/ubuntu/+source/ca-certificates...
It is obvious the report did not get the proper visibility.
It is not clear why Ubuntu does not support shared certificates if Debian does.
You can contact at the ubuntu-hardened mailing list or ping on #ubuntu-security (Freenode).

"Back to your report at Launchpad, https://bugs.launchpad.net/ubuntu/+source/ca-certificates...

That is, unfortunately, my normal experience for Ubuntu bugs I have filed. Perhaps I'm just unlucky, or care about esoteric topics.
"It is not clear why Ubuntu does not support shared certificates if Debian does.

Debian doesn't get it right either. The various copies of NSS there also each use their own copies of libnsscbki.so instead of having it symlinked to p11-kit-trust.so to use the system trust.

I'd love to see update-ca-trust and update-ca-certificates replaced by a D-Bus service that TLS libraries would call into that would perform centralized certificate verification, and as a by-product, produce audit logs and the kind of statistics you describe in your post.

Hmm... Why is Canonical basing this LTS release on 4.15, which kernel.org lists as EOL, and not on 4.16, like Fedora 28?

They should really have used 4.14, which is an LTS kernel. 4.16 will not be, so it will soon end up EOL just like 4.15, but there we are. Seems the major distributors pay no attention to the LTS kernels, and think they can do better themselves....

Maybe the choice of kernel was down to the time at which it was frozen and the point at which the Spectre/Meltdown mitigation patches had reached. Never ascribe to malice or stupidity that which is simply due to lack of time and a release schedule.

In practice don't they migrate the kernel version in the Ubuntu LTS release to a convenient kernel LTS version in time? (They did with 16.04, IIRC.)

They probably wanted all the updated AMD drivers that came after the last LTS.

Canonical Kernel Team provides stable support for kernels in use in Ubuntu beyond the regular upstream Supported / LTS status, to cover Ubuntu LTS and ESM schedules.

v4.15 was picked as target series for 18.04 LTS early in the development cycle before Spectre/Meltdown was known. The decision is mostly based on the latest released version, with enough time for integration and testing. v4.16 was cutting it way too close to the fixed release schedule for 18.04 LTS.

Note that Ubuntu LTS releases are eligible to receive hwe kernels, thus e.g. this v4.15 kernel will be availble as an -hwe kernel on 16.04 LTS. Ditto, later Ubuntu released kernels will be available on 18.04 LTS as well, starting with the 18.04.2 release onwards. Thus in practice v4.15 based kernel is good enough, and newer kernels (with more hardware support) will be available in the future as well.

Well, I'm running it now on my work/developer machine. So far, so good, but I still don't think I can live with "we know best" GNOME. It looks superficially pretty, but it's like working in a room where the walls keep shrinking around you. So I'll install another desktop environment soon, but otherwise it seems fairly solid underneath....

I use and recommend Xubuntu for this task. 18.04 is coping with GNOME app weirdness much better than 16.04 did.

Ubuntu 18.04 LTS DNS problem

Posted Apr 29, 2018 22:20 UTC (Sun) by dougg (guest, #1894) [Link] (1 responses)

First noticed in 17.10 now I'm seeing more laptops with what seems like a DNS resolution problem in release18.04 . My home network has its own dhcp and DNS setup running on a pair of RPis using Raspbian (Deb 9) . Everything starts out fine when laptops are turned on by which I mean that my local headless devices like printers can be accessed. However after one of those laptops comes back online after a suspend (say having not been used for several hours) its DNS is screwed. Some DNS server is being used but its not mine, so that <everything>.<my_domain> ends up up the external interface of my firewall. The solution is to run 'systemctl restart systemd-resolved' which fixes the DNS resolution until the next time that laptop suspends. Other Debian machines, FreeBSD and W10 on my network don't have this problem. Anyone else seen something like this?

Yes, I had the same issue.

I forget what I did exactly, but I went to this page for pointers:

Finally! Off with ifupdown, long live netplan! Are not you glad from this change ? :>

ifupdown and netplan are...

Posted Apr 30, 2018 20:57 UTC (Mon) by iam.TJ (guest, #56644) [Link]

.. orthogonal to each other.

ifupdown is the legacy network management tool replaced by NetworkManager or systemd-networkd.

Netplan(.io) is a boot-time network configuration parser and renderer - it currently converts its YAML into either systemd-networkd (servers) or NetworkManager (desktops) run-time configuration on every boot.

/etc/netplan/*.yaml -> /run/systemd/network/
/etc/netplan/*.yaml -> /run/NetworkManager/
