Already in final beta? That's Madagascar: Ubuntu 20.04 'Focal Fossa' gets updated desktop, ZFS support

(2020/04/06)


Canonical has dropped a final beta of Ubuntu 20.04 "Focal Fossa", set for full release on 23 April.

Ubuntu has a six-monthly release cycle, with a long-term support release every two years. Ubuntu 20.04 is one of those, so this will get hardware and maintenance updates until 2022, maintenance updates until 2025, and extended security maintenance until 2030. Other releases by contrast are only supported for nine months.

Canonical says that 95 per cent of all Ubuntu installations are LTS – so for those users, this is the first new release since 18.04. The Linux kernel in 20.04 is 5.4, which is also a long-term release.

Ubuntu 20.04 is now in final beta

A fossa is a cat-like creature endemic to Madagascar and the name has inspired some [2]striking wallpaper in the new OS.

The most visible difference in 20.04, if you are running the desktop edition, is the update to GNOME 3.36. The login screen now has an option to show the password, there's a new graphical boot menu, a new design for the system menu, and claimed performance improvements.

ZFS support is improved in this version, but still marked experimental

ZFS, an alternative file system, is now at OpenZFS version 0.8.3. This [4]includes native encryption, device removal (for removing drives from a storage pool), and Pool Trim for more efficient use of SSD storage. ZFS is still flagged as an experimental option on install. Bundled applications are upgraded, for example, to Firefox 74, Thunderbird 68.6, and LibreOffice 6.4.

On Ubuntu Server, the biggest news is the upgrade of QEMU (Quick Emulator) to version 4.2. Among many new features is support for a minimalist [5]microvm machine type, inspired by AWS [6]Firecracker for container-type workloads with better isolation. Nested virtualisation is now "considered fully supported", according to the [7]release notes . The libvirt library is now at version 6.0, with new features including direct access to NVMe drives.

Other product upgrades in Ubuntu Server include PHP 7.4, Ruby 2.7 and PostgreSQL 12.

We took the new desktop build for a quick spin. The differences from 19.10 are noticeable but not dramatic. An attempted ZFS install on Hyper-V failed with a kernel panic but worked after reboot.

Glimpse is a featured application in the Ubuntu store

In the Ubuntu application store, the first thing we saw was Glimpse, the fork of the GIMP image editor [9]primarily intended to fix the "problematic" name. The project has won enough support to progress to wide availability. There is some evidence of controversy, with 28 out of 62 user ratings awarding just one star, and 23 awarding five stars. Reviews show general appreciation, though.

The install wizard invites you to connect an online service so we hooked up to a Microsoft account to see what would happen. The answer was not much, aside from a scary permissions dialog. There is no integration with OneDrive, for example. It looks as if linking to a Google account instead might work better, with Google Drive support promised.

You can hook up Ubuntu to online accounts, but in this case with little benefit

You do not have to use the GNOME version. Other options range from Kubuntu based on KDE and using the Plasma desktop, the lightweight Lubuntu, and others including Budgie, Kylin (Chinese), MATE, Ubuntu Studio aimed at design and multimedia, and Xubuntu with Xfce (also lightweight). You can find the releases [11]here . ®

ZFS is for dedicated file-servers

_LC_

I feel the obligation to tell the people that ZFS is only useful on dedicated file-servers (as Ubuntu is unlikely to be used for those). Some people read the specs and decide to run ZFS on their desktop systems. That is stupid in many ways. Do yourself the favor and don't.

Surely you're not hinting that they should use btrfs instead?

Software package management is heading towards using ZFS snapshots. It'll be the way you get software, or uninstall it. It's a pretty neat idea.

There's many features of ZFS that are highly attractive to desktop usage. It's far, far more flexible for different storage requirements inside a single machine than something like the (venerable but certainly respected) ext filesystems, and why wouldn't a desktop user want flexibility in how their disparate data types are stored?

"That is stupid in many ways. Do yourself the favor and don't."

Could you elaborate please?

Good to see

it is still in development in these strange times; though maybe all the developers are just working from home on it anyway.

Personally I'll wait for the Linux Mint version of it to come along. Looking forward to something a tad different. Still using Mint 18.3 Cinnamon.

It's pronounced foosa BTW. I was fortunate to be involved with tracking them for a research project a few years back.

The Poet Whose Badness Saved His Life
The most important poet in the seventeenth century was George
Wither. Alexander Pope called him "wretched Wither" and Dryden said of his
verse that "if they rhymed and rattled all was well".
In our own time, "The Dictionary of National Biography" notes that his
work "is mainly remarkable for its mass, fluidity and flatness. It usually
lacks any genuine literary quality and often sinks into imbecile doggerel".
High praise, indeed, and it may tempt you to savour a typically
rewarding stanza: It is taken from "I loved a lass" and is concerned with
the higher emotions.
She would me "Honey" call,
She'd -- O she'd kiss me too.
But now alas! She's left me
Falero, lero, loo.
Among other details of his mistress which he chose to immortalize
was her prudent choice of footwear.
The fives did fit her shoe.
In 1639 the great poet's life was endangered after his capture by
the Royalists during the English Civil War. When Sir John Denham, the
Royalist poet, heard of Wither's imminent execution, he went to the King and
begged that his life be spared. When asked his reason, Sir John replied,
"Because that so long as Wither lived, Denham would not be accounted the
worst poet in England."
