Ubuntu is a complete desktop Linux operating system, freely available with both community and professional support. The Ubuntu community is built on the ideas enshrined in the Ubuntu Manifesto: that software should be available free of charge, that software tools should be usable by people in their local language and despite any disabilities, and that people should have the freedom to customize and alter their software in whatever way they see fit. “Ubuntu” is an ancient African word, meaning “humanity to others”. The Ubuntu distribution brings the spirit of Ubuntu to the software world.

What’s New in Ubuntu 17.04

Ubuntu Normal Release, version 17.04 (Zesty Zapus), was released on April 13, 2017.

32-bit PowerPC Support Dropped

Networking

The default DNS resolver is now systemd-resolved.

Swap

For new installs, a swap file will be used instead of a swap partition.

Fresh installs of Ubuntu 17.04 will no longer require a swap partition that’s (at least) twice the RAM size. It makes little sense on modern systems that have more memory available.

So, instead, Ubuntu 17.04 Zesty Zapus uses a swapfile by default. Sizing of swap files is different to the swap partitions and typically use no more than 5% of free disk space (or 2048MB of RAM), which is another potential benefit.

Updated Packages

Ubuntu 17.04 is based on the Linux release series 4.10.

If you’re planning on installing Ubuntu on a machine sporting a Kaby Lake or Ryzen CPU, you may want to go with Ubuntu 17.04. The latest kernel version (4.10) has improved support for multithreading and power management with both AMD and Intel’s new CPU lines.

Ubuntu 17.04 includes the Linux kernel 4.10, which is great news for anyone looking to run the release on AMD Ryzen or Intel Kaby Lake systems. Gamers will also appreciate the inclusion of MESA 17.0.2 and the X.Org Server 1.19.2 is also included by default.

Driverless Printing

Driverless printing works out-of-the box with any printer that uses either IPP Everywhere or Apple’s AirPrint. The list of printers that use IPP Everywhere is quite short, and currently limited to HP units. By comparison, Apple’s AirPrint is supported by a litany of printers out there today.

Now supports printers which allow printing without printer-specific drivers. These printers are IPP Everywhere and Apple AirPrint printers, but also some PDF, Postscript, and PCL printers work. This way connecting a printer gets as easy as connecting a USB stick.

The printers can get connected via network or USB.
The setup of IPP Everywhere and Apple Airprint printers should occur fully automatically. You only need to plug in your USB printer or connect your network printer to the local network.

On driverless USB printers (IPP-over-USB) you find the web administration interface under http://localhost:60000/ (if more than one printer is connected, the other ones are on port 60001, 60002, …). It is highly recommended to access the interface with Firefox.

If you have a WiFi printer which does not allow to configure the WiFi access by its front panel, try to connect it via USB. If it is an IPP-over-USB printer you can configure it by its web interface now and then disconnect USB and use WiFi.
If you have an HP multi-function device with scanner, prefer using it with the HPLIP driver as you were used to. When using in driverless mode you will not be able to scan. system-config-printer takes automatically care of this.
If you have a multi-function device with scanner and the scanner is not supported by simple-scan/xsane/SANE, look for a scanning function in the web administration interface. Thanks to IPP-over-USB this will also be possible with many USB-connected devices.
Driverless printing is supported on both Ubuntu Desktop and Ubuntu Server.

If you’re using a multifunction HP printer to scan documents, Ubuntu warns that you’ll still need to use the HPLIP driver, since driverless printing doesn’t support scanning on HP units.

Ubuntu Desktop

Apps provided by GNOME have been updated to 3.24. Exceptions are the Nautilus file manager (3.20), Terminal (3.20), Evolution (3.22), and Software (3.22).

The Calendar app now has a Week view.

gconf is no longer installed by default since it has long been superseded by gsettings. Note that statistics and preferences for the Aisleriot card games will be reset when upgrading to 17.04.

There’s the latest LibreOffice 5.3 (aka the one you can enable the ‘Ribbon’ interface in); the default Calendar app picks up a handy week view; and key essentials Firefox and Thunderbird are shipping their latest stable versions, too.

With the bulk of GNOME 3.24 available in Zesty you also get new versions of many other apps and tools, except for the stock Terminal emulator (which stays on v3.20), the Nautilus file manager ( on v3.20) and Ubuntu Software ( on v3.22, but with some additional features, like Snap URL support).
