SparkyLinux 5: Great All-Purpose Distro for Confident Linux Users

The latest edition of SparkyLinux, version 5.0 “Nibiru,” finds its true calling as a Linux distro that falls between those that are beginner-friendly and those that require some amount of Linux knowledge.
You can get a variety of editions with different desktop offerings, such as E19, LXDE and Openbox, from versions 4.5, 4.6 and 5.0. However, the best option now is the collection of upgraded features in the latest release.
SparkyLinux 5.0 is based on the testing branch of Debian. It features customized lightweight desktops that include LXDE, Enlightenment, JWM, KDE, LXQt, Openbox, MATE and Xfce. It comes with multimedia plugins, a selected sets of apps, and its own custom tools to ease different tasks.
Regardless of which lightweight desktop or window manager option you prefer, SparkyLinux gives you an operating system that is out-of-the-box ready for use. If you are a Linux purist with very particular distro demands, you can opt for one of the SparkyLinux minimalist releases.
For example, Sparky MinimalGUI gives you Openbox or JWM desktops under the hood and MinimalCLI provides a text-based interface. Both alternatives let you use the Sparky Advanced Installer to load the base system with a minimal set of applications.

Screen Ordering

Previously, you would go through the install journey by picking your spell, selecting a cloud, modifying charm options, and then waiting for bootstrap/applications to be completely deployed prior to performing the post processing steps. In this latest update we’ve moved all steps to be completed prior to any of those longer blocking tasks.

This allows you to see the complete picture and giving you the ability to go back and make updates to your configuration items prior to running the longer tasks of the deployment.

Deployment resilience

We use a mechanism for determining when a deployment has “finished”, meaning, all hooks have been fired and each application is in a ready state to handle the next set of instructions from the installer. In some cases an application may get into a state of error but quickly resolve itself.

This was causing us some issues as we were taking a very strict approach that if there is an error in the application then the deployment should fail. Even though this is the proper thing to do we’ve made a decision that if the application is able to fix itself then we shouldn’t pass on that failed experience to the user since technically the deployment is able to finish and function as intended.

To combat this we’ve made our deployment checker a little more lenient and performing retries (up to 5 times) to validate if an application does fix itself. However, since an error was seen in the application it should not go unnoticed and needs to be fixed in the charm itself. In our integration tests we have an environment variable CONJURE_UP_MODE that can be set to test and gives us the ability to fail on charm failures and get those bugs reported upstream and resolved.

Spell authors can make use of this feature in their own spells by updating the 00_deploy-done script with the following bits:

#!/bin/bash set -eux . "$CONJURE_UP_SPELLSDIR/sdk/common.sh" retry_arg="-r5" if [[ "${CONJURE_UP_MODE-}" == "test" ]]; then retry_arg="" fi if ! juju wait $retry_arg -vwm "$JUJU_CONTROLLER:$JUJU_MODEL"; then setResult "Applications did not start successfully" exit 1 fi setResult "Applications Ready" exit 0 

Getting these changes

Installing the snap from the edge channel will give you the latest work outlined in these developer summaries:

sudo snap install conjure-up --classic --edge

 


 
			
			
			
		

It’s Now Possible to Install the Linux 4.13 RC2 Kernel on Your Slackware Distro

GNU/Linux developer Arne Exton is known for creating and maintaining a bunch of Linux-based operating systems, as well as for packaging the latest kernels for Slackware Linux.
Slackware is the oldest GNU/Linux distro that’s still in active development, and it recently turned 24 years old. To celebrate this event, Arne Exton managed to create a custom 64-bit kernel for Slackware 14.2 based on the recently released Linux 4.13 RC2 kernel, which brings support for new hardware and other optimizations.
If you want to install Arne Exton’s Linux 4.13 RC2 kernel on your 64-bit Slackware 14.2 distro, you should first make a backup of the /boot/vmlinuz file as it will be overwritten during the installation. Also, you may need to modify your GRUB bootloader configuration if you’ve done some changes there yourself.
Nvidia GPU users will also need to remove the blacklisting of the open-source Nouveau graphics driver in the nvidia-installer-disable-nouveau.conf and blacklist.conf files located in /etc/modprobe.d before attempting to install this custom Linux 4.13 RC2 kernel.

ss: another way to get socket statistics

In an earlier blog post I mentioned ss, another tool that comes with the iproute2 package and allows you to query statistics about sockets. The same thing that can be done with netstat, with the added benefit that it is typically a little bit faster, and shorter to type.

Just ss by default will display much the same thing as netstat, and can be similarly passed options to limit the output to just what you want. For instance:

$ ss -t State       Recv-Q Send-Q       Local Address:Port                        Peer Address:Port ESTAB       0      0                127.0.0.1:postgresql                     127.0.0.1:48154 ESTAB       0      0            192.168.0.136:35296                      192.168.0.120:8009 ESTAB       0      0            192.168.0.136:47574                     173.194.74.189:https

[…]

ss -t shows just TCP connections. ss -u can be used to show UDP connections, -l will show only listening ports, and things can be further filtered to just the information you want.

I have not tested all the possible options, but you can even forcibly close sockets with -K.

One place where ss really shines though is in its filtering capabilities. Let’s list all connections with a source port of 22 (ssh):

$ ss state all sport = :ssh Netid State      Recv-Q Send-Q     Local Address:Port                      Peer Address:Port tcp   LISTEN     0      128                    *:ssh                                  *:* tcp   ESTAB      0      0          192.168.0.136:ssh                      192.168.0.102:46540 tcp   LISTEN     0      128                   :::ssh                                 :::*

And if I want to show only connected sockets (everything but listening or closed):

$ ss state connected sport = :ssh Netid State      Recv-Q Send-Q     Local Address:Port                      Peer Address:Port tcp   ESTAB      0      0          192.168.0.136:ssh                      192.168.0.102:46540

Similarly, you can have it list all connections to a specific host or range; in this case, using the 74.125.0.0/16 subnet, which apparently belongs to Google:

$ ss state all dst 74.125.0.0/16 Netid State      Recv-Q Send-Q     Local Address:Port                      Peer Address:Port tcp   ESTAB      0      0          192.168.0.136:33616                   74.125.142.189:https tcp   ESTAB      0      0          192.168.0.136:42034                    74.125.70.189:https tcp   ESTAB      0      0          192.168.0.136:57408                   74.125.202.189:https

This is very much the same syntax as for iptables, so if you’re familiar with that already, it will be quite easy to pick up. You can also install the iproute2-doc package, and look in /usr/share/doc/iproute2-doc/ss.html for the full documentation.

Try it for yourself! You’ll see how well it works. If anything, I’m glad for the fewer characters this makes me type.

Canonical Is Working on Adding Captive Portal Detection to Ubuntu 17.10

Canonical’s Ubuntu Desktop Director Will Cooke reports today on the latest developments done by his team for the upcoming Ubuntu 17.10 (Artful Aardvark) operating system.
Not so much hot stuff this week on the Ubuntu land, as Canonical was working lately on updating various GNOME apps that it packaged as Snaps in the edge channel of the Snappy Store, based on the GNOME 3.24 platform Snap and content interface, as well as on cleaning the ISO images of deprecated components.
But it also looks like Canonical is working on adding captive portal detection to Ubuntu 17.10, which will make it possible for the NetworkManager network connection manager tool to support disabling of connectivity checking via the D-Bus interface by adding a new option in the Privacy settings panel.
Apart from the ISO cleaning, NetworkManager improvements, and Snap packaging of GNOME apps, Canonical has been working lately on implementing a workaround for the GDM (GNOME Display Manager) bug that blocked the A2DP high-quality Bluetooth profile from being activated in the user session.
As well as on adding some more low graphics mode improvements to the Unity 7 user interface targeting only the long-term supported Ubuntu 16.04 LTS (Xenial Xerus) operating system series, which Canonical say it will benefit those with low powered systems and people who run Ubuntu on a virtual machine.

Ubuntu Desktop Weekly Update: July 24, 2017

GNOME

We’re working on adding captive portal detection to Artful. We think it would be good if there were an option in the privacy settings to enable or disable this. We’ve done some initial work as preparation – some patches have been submitted to Network Manager’s upstream to enable an option to be created. They are currently awaiting review.

ISO cleanups

Work continues to move deprecated components out of the desktop ISO and to universe. This week’s list includes indicator-application and indicator-messages.

Snaps

Updated versions of gedit, gnome-sudoku, quadrapassel, gnome-dictionary, gnome-calculator, and gnome-clocks are in the edge channel of the store now built using the gnome-3-24 platform snap and content interface.

Video & Audio

A workaround has been uploaded for GDM which was blocking the A2DP high quality bluetooth profile from being activated in the user session.

Updates

  • Libreoffice 5.3.4, with a workaround for an i386 kernel issue which had been blocking the previous version.
  • GStreamer 1.12.2
  • Evolution 3.24.2
  • The nplan autopkgtest got fixed, unblocking the network-manager update.

Unity 7

16.04 continues to be supported, and we’ve been working on some further improvements for Unity that are targeted there. In particular there are improvements currently being developed to the low graphics mode that will benefit users of low powered systems and VMs.

QA

GNOME Software has a documented test plan now.

Debian 9.1 GNU/Linux Released With 26 Security Fixes

The Debian Project has announced the first update of Debian 9 Stretch, i.e., Debian 9.1. The first point release to this latest stable Debian branch comes with many security issue fixes and other adjustments.
Many of you might be already knowing that Debian 9.1 doesn’t constitute a new Debian version or bring new features. Instead, it only updates the existing packages. So, one doesn’t need to perform an upgrade or reinstall if he/she has already installed the all recent updates in the past few months.
Talking by the numbers, this release has brought 54 important corrections to different packages, including the likes of apt, openssh, perl, systemd, grub-installer, etc.
Apart from that, 26 security updates have also been added. In other related news, in May, Devuan GNU+Linux 1.0 was released. It was the first ever stable release of this Debian-without-systemd fork.

Dustin Kirkland: Ubuntu 18.04 LTS Desktop Default Application Survey

Back in March, we asked the HackerNews community, “What do you want to see in Ubuntu 17.10?”: https://ubu.one/AskHN

A passionate discussion ensued, the results of which are distilled into this post: http://ubu.one/thankHN

In fact, you can check that link, http://ubu.one/thankHN and see our progress so far this cycle. We already have a beta code in 17.10 available for your testing for several of those:

And several others have excellent work in progress, and will be complete by 17.10:

In summary — your feedback matters! There are hundreds of engineers and designers working for *you* to continue making Ubuntu amazing!

Along with the switch from Unity to GNOME, we’re also reviewing some of the desktop applications we package and ship in Ubuntu. We’re looking to crowdsource input on your favorite Linux applications across a broad set of classic desktop functionality.

We invite you to contribute by listing the applications you find most useful in Linux in order of preference. To help us parse your input, please copy and paste the following bullets with your preferred apps in Linux desktop environments. You’re welcome to suggest multiple apps, please just order them prioritized (e.g. Web Browser: Firefox, Chrome, Chromium). If some of your functionality has moved entirely to the web, please note that too (e.g. Email Client: Gmail web, Office Suite: Office360 web). If the software isn’t free/open source, please note that (e.g. Music Player: Spotify client non-free). If I’ve missed a category, please add it in the same format. If your favorites aren’t packaged for Ubuntu yet, please let us know, as we’re creating hundreds of new snap packages for Ubuntu desktop applications, and we’re keen to learn what key snaps we’re missing.
