The Ubuntu 19.04 release is now available to download, six months after development started. In this post we look at the new features and changes this update brings.
If you know Ubuntu Releases at all, you should remember that there's usually another release between 19.04 and 20.04 - it's 19.10. All the x.10 releases are called interim releases - they're issued about 6 months after each x.04 release and are not supported even for a full year.
But first things first: how do you get it?
If you want to download Ubuntu 19.04 right now, you can: just skip on down to the download section of this post to snag yourself a minty-fresh ISO.
You can also upgrade to Ubuntu 19.04 from 18.10 without reinstalling. Just wait for the ‘upgrade prompt' to appear on your desktop (sometime after April 18) or force an upgrade by using the command in the linked guide.
Regardless of the way in which you get it, chances are you'll want to know what's new and what's changed once you've got it, so keep reading to learn more!
The Ubuntu 19.04 release date is April 18, 2019. Daily builds became available in November 2018, while the first Ubuntu 19.04 beta released on March 28.
Other milestones during 'Disco Dingo' development included feature freeze on February 21, 2019, UI freeze on March 14, 2019, and kernel freeze on April 1, 2019.
Ubuntu 19.04 is the fourth version of Ubuntu to ship with the GNOME Shell desktop, but the first version to actually feel like the switch was worth it!
Don't get me wrong: I love the GNOME Shell workflow, the UI, the UX. It runs great on Fedora, Arch and Manjaro (or so I'm told).
But until now, Ubuntu's implementation of the GNOME Shell desktop has handled like an underwater level in Sonic the Hedgehog, i.e. pretty sluggish.
Thankfully the treacle-footed feeling that afflicts earlier versions is absent in the Disco Dingo. Here, the Ubuntu desktop finally feels as fast and as fluid as it did during the late Unity desktop days.
The uptick is the result of work by both upstream and downstream developers. Memory enhancements, CPU optimisations, and animation tweaks combine to make an Ubuntu desktop experience that feels infinitely more responsive.
Improved performance is what defines the ‘Disco Dingo', so if you only take one thing away from reading this post, let it be this.
Ubuntu 19.04 ships with the Linux 5.0 kernel release.
To quote our own post on its release, this kernel version comes with ‘a bucket full of improvements'. Support for AMD FreeSync, Raspberry Pi touchscreens, and Adiantum encryption sit among the highlights.
Mesa 19.0 is available out of the box in 19.04. This is the latest development release of the popular open-source graphics driver and ensures those of you using compatible graphics cards get the best performance on Linux.
If you use a machine with an NVIDIA graphics card you now have the option to install proprietary NVIDIA graphics drivers during installation. No, it's not essential, but it certainly helps cut down on the amount of post-install things-to-do.
Similarly, those who choose to install Ubuntu 19.04 in a VMware virtual machine will be pleased to hear that (where detected) the open-vm-tools package is installed as part of the install process.
Finally, since we're on the subject of graphic drivers, keep an eye out for the new ‘safe graphics mode' option in the Grub menu. Choosing this will boot Ubuntu with 'NOMODESET' turned on. If you're having issues with graphics cards or graphics drivers this mode will prove invaluable.
Shipping the latest GNOME 3.32 release delivers a wealth of improvements. Features like night-light intensity control, rounded user avatars, faster Google Drive access, and advanced application permission are ready to play with from the get-go.
The new version of Nautilus included support for file favouriting.
To favourite a file just select it, right click, and choose the 'Star' option.
You can quickly view all your starred files by selecting the ‘Starred' bookmark in the file manager sidebar.
The Disco Dingo features a new background wallpaper and an updated Yaru GTK & icon theme.
The Yaru icon set switches from the uniform ‘squircle' shape for a liberal mix of icon shapes. This might not sound like a big deal but it makes a massive improvement to the look of the apps screen, which now has a cohesive and consistent appearance to it.
On the subject of icons, the new upstream Adwaita icon set is available to install from the 19.04 repos (should you want to try it out). Just open a Terminal window and run sudo apt install adwaita-icon-theme and switch icon theme using the Tweaks tool.
With the update to Nautilus 3.32, Ubuntu lost the ability to show icons on the desktop. To remedy the (rather critical) omissions, a new GNOME Shell extension is included. It's called 'Desktop Icons' and it does exactly what you'd expect it to: show icons on the desktop.
Alas, it's not a fully-formed replacement. The new extension lacks some of the functionality we're all (probably) used to.
For example, the ‘desktop icons' extension doesn't let you drag and drop files from the desktop onto app shortcuts or into app windows. Instead, you have to open Nautilus > Desktop and do it via the file manager.
Ubuntu 19.04 offers experimental fractional scaling support in the (optional) Wayland session. Scaling values available include 125%, 150% and 200%.
There's also experimental fractional scaling support on Xorg for HiDPI displays. While this feature isn't ready for the prime time you can turn it on using a command-line switch.
An option to enable location detection (via geo-clue, useful when travelling) has been added to the set-up tool.
There's also better integration of Canonical's LivePatch service (though the feature itself only supports LTS releases).
There's a new header bar in the default Terminal emulator (though it can be disabled) plus a few new features, like ‘find' and ‘read only' mode.
File indexing and search service Tracker is installed by default. This lets desktop apps to keep tabs on recently used files and helps to improve search times.
Mozilla Firefox 66, Thunderbird 58 and LibreOffice 6.2.2 all come as standard (though oddly client-side decoration in Firefox is not enabled by default, despite being available).
Although the Ubuntu Software store is kept back on version 3.30 it still proffers access to the latest apps on the Snapcraft Store.
GSconnect, the handy extension that lets you connect an Android phone to Ubuntu wirelessly, didn't make it in to this release. However, the add-on is available in the archives and isn't difficult to set up.
Likewise, GNOME Clocks was scheduled to be part of the default app selection but, alas, didn't make it in in time. There's also no revamped installer slideshow, something Ubuntu founder Mark Shuttleworth is keen to explore.
You can download Ubuntu 19.04 desktop as a 64-bit .ISO image by hitting the button below:
Other Ubuntu flavours are also available, including Ubuntu MATE 19.04 (ideal for older hardware) and Kubuntu (perfect for those who prefer KDE).
Despite the name, Ubuntu 19.04 is more of a mid-afternoon tea dance than a raucous disco. That's not a negative per se, it's just that this release feels more like a familiar, choreographed, routine update, rather than trying to throw shapes on the distro dance floor.
But with a lighter, more responsive feel, the latest software, and a new Linux kernel, this newest version of Ubuntu has lot to tempt you with.
Changes in brief:
In this tutorial, you will learn how to install Python Pip onto Ubuntu 19.04. You will also learn how to install and manage packages, as well as listing packages and their version available by Pip repository.
Pip is a package management system for Python that allows you to install and manage software packages written in Python. Very similar to apt on Ubuntu and Debian, or yum on Red Hat and Centos, with the exception that it is purposely built for the Python community.
Python Pip is available from the Ubuntu 19.04 source repositories, and it can easily be installed without additional work. The version available for Ubuntu 19.04 is 18.1.
Much like with Ubuntu 18.04 there are two versions of Pip supported in the source repos — Pip for Python 2.7 and Pip3 for Python 3. The latter is the recommended version, as the former will be deprecated in the near future.
To install Pip for Python 3, run the following command.
To install Python Pip for Python 2.7, use the following command.
An alternative to installing Pip from the Ubuntu Apt repository is to run an installation script provided by pypa.com. This is useful for distribution that do not have Pip available in their package manager, or when you want more installation options.
Apt will not be aware of Pip when installed using this script. If Pip is already installed via Ubuntu's package manager, installing it again using the installation script could put your server into an inconsistent state.
Download the installation script for Pip from pypa.com
Execute the script using Python
Pip is capable of updating itself using the pip install command. When executed, Pip will look for an updated version of itself and then install it.
To update Pip, run the following command
To install a new package using Python Pip, the pip install command is used with the name of the package to be installed.
For example, to install Ansible through Pip you would run the following command.
Packages are frequently updated, and to ensure you are running the latest version that fix bugs, security vulnerabilities, or add new features, you use the pip install command with the -U flag.
pip install -U PACKAGE_NAME
For example, to update the Ansible package you would run the following command.
Terraria nintendo switch release date 2018. pip install -U ansible
To uninstall and remove packages from Ubuntu 18.04, the pip uninstall command is used.
For example, to uninstall the Ansible package from Ubuntu 18.04 you would run the following command.
To list packages installed using Pip, you can use the list command. The pip list command will output each install package with its version.
Keeping an eye on outdated packages is simply using the outdated list option. A nicely formatted list of outdated packages that are installed on the system by pip will be outputted.
To show detailed information about a package that is installed on the server, the pip show command can be used. Included in the output of this command is the package name, version, a short summary, and a dependency tree.
