Virtualbox policy changes

As you might already know, Debian hasn’t included the Virtualbox packages in Debian Stretch. When SolydXK 9 was released we recommended to use the repository to install and maintain Virtualbox.

To make installing Virtualbox simpler we’ve added the Virtualbox packages from Debian Stretch backports to our own repository. These packages are updated on a daily basis. There is no difference between the Virtualbox packages in the backports repository and our own repository.

If you are currently using the repository you don’t have to change anything at all. We decided to offer the backports packages in our own repository for your convenience.

Mozilla Shield Studies and other unwanted addons

Recently one of our team members, Ilu, has reported Mozilla’s misuse of Firefox’s addons. One of those addons is called “Shield Studies” and described by Mozilla’s wiki as:

Shield Studies is a function of the Shield project that prompts a random population of users to help us try out new products, features, and ideas.

As users are randomly selected there is not much the team can do about this. However, I’ve updated the firefox-solydxk-adjustments package for solydxk-9 and the Enthusiast’s Editions but this will only prevent the use of these addons for newly created users. Existing users can either disable the addons in Firefox’s preferences pane or prevent the addons from being installed in the first place by manually editing their prefs.js file and add the following entries:

user_pref("experiments.enabled", false);
user_pref("experiments.manifest.uri", "");
user_pref("experiments.supported", false);
user_pref("experiments.activeExperiment", false);
user_pref("experiments.activeExperiment", false);
user_pref("network.allow-experiments", false);
user_pref("extensions.pocket.enabled", false);
user_pref("dom.flyweb.enabled", false);
user_pref("extensions.shield-recipe-client.enabled", false);
user_pref("extensions.shield-recipe-client.api_url", "");

The prefs.js file is found in ~/.mozilla/firefox/your_user_profile/

Community Editions release 201709

Grizzler has released the 32-bit ISOs based on Debian Stretch and the Enthusiast’s Edition ISOs based on Debian Buster.

You can download both 64-bit and 32-bit versions of the Enthusiast’s Editions.

You can download the ISOs from the main site:

Do not forget to verify your download before you run the ISOs.

If you already have a running SolydXK system you can use the USB Creator to create a bootable USB pen drive.

In any other case you can find instruction here:

Goodbye to our team member

Jocelyn (Ane Chemepenois on our forum) has decided to leave the SolydXK team. The increased pressures of fatherhood has forced him to take a step back 😉

Jocelyn has been a valuable team member for a very long time and I always liked working with him. Being a father of two I understand that it is important to prioritize.

On behalf of the team I thank you for all the work you have done, we wish you all well and we hope to see you again in the future.

All the best,

SolydXK 9 released!

In the past three weeks we have been testing, improving, developing and exercising parts of our vocabulary that our mothers didn’t even know we had but finally we are satisfied with the result. It is time to release the new SolydX and SolydK version 9.


  • New themes for SolydX and SolydK. You can choose a light or dark theme.
  • Solydxk Systems has a GUI now where you can encrypt partitions (and your USB flash drive), localize your system, select the fastest repositories, hold back packages and cleanup your system. The encryption part of this application is functioning but still in beta. Use at your own risk!
  • The backport repository was removed by default but can be enabled in the new SolydXK System application.
  • The solydx/k-info packages were integrated in the solydx/k-system-adjustments packages and are now obsolete.

Discontinued applications

  • Updatemanager is replaced by applications from Debian’s repository with similar functionalities and the new SolydXK System GUI.
  • SolydXK Softwaremanager has been replaced with an application from Debian’s repository.
  • Lightdm Manager was replaced with lightdm-gtk-greeter-settings
  • Device Driver Manager (DDM)
  • SolydXK Conky
  • (SolydK) XKSudo
  • (SolydK) kcm-ufw
  • (SolydX) User Manager was replaced with gnome-system-tools
  • (SolydX) Sambashare was replaced with gadmin-samba

Upgrading existing systems
There are two ways to upgrade your SolydXK-8 system to SolydXK-9: a fresh install or upgrading your existing system. It is preferred to download the ISO and do a fresh install (backup your data first!) but if you prefer to upgrade your system we have prepared a script to aid you in the process:

After download, unpack, make the script executable and run the script.
Important: check the output of the apt commands. All systems are configured differently and you might remove packages that you really don’t want to be removed!

If you do not want to upgrade just yet, don’t worry! After the release of SolydXK-9 I will keep the solydxk-8 repository available for another year. Firefox and Thunderbird will be updated in the solydxk-8 repository but they are not tested with SolydXK-8. Again, use them at your own risk!

SolydX RPI
Unfortunately, I have to stop developing SolydX RPI. It was fun doing it but it simply took too much time and effort and I still couldn’t get it to function to the standards I want for SolydXK.

Localized versions
The Dutch version is ready for download. The rest will follow and I will let you know when they come available.

Community Editions
Frank is working hard on the 32-bit and Enthusiast’s Editions. When they are ready I will let you know.

You can find more information, and download the ISOs on our product pages:

Beta testing SolydXK-9

Debian has released Stretch and we’ve started testing the beta ISOs.

I’ve started a topic on our forum for this purpose. It includes beta ISOs for SolydX and SolydK, the changes that were made and beta scripts to upgrade existing SolydXK-8 systems to SolydXK-9.

We do need your help testing the ISOs and upgrade scripts. So, if you have some time to spare, please visit our forum and get those ISOs and scripts:

Main site up again

It seems that our main site was down for the past 8 hours.

Users were presented with an error message on the WordPress Jetpack plugin. That has been solved now and the site is available again.

My apologies for the inconvenience.

Update – getting ready for Stretch

In preparation of Debian Stretch becoming the next stable we decided to make some changes in the SolydXK specific configuration packages which means that the following packages are now obsolete:

  • solydx-info
  • solydk-info
  • solydx-system-adjustments
  • solydk-system-adjustments

They are being replaced by these packages:

  • solydx-system-adjustments-8
  • solydk-system-adjusmtents-8

When these new packages are successfully installed, the old system-adjusmtents packages will be removed with the next boot or you can safely remove it manually by the following command:

apt purge solydx-system-adjustments


apt purge solydk-system-adjustments


SolydK users might want to remove these packages unless you are using the provided icon theme and want to keep using these icons:

  • evolvere-icon-theme-vivid-sunken
  • evolvere-icon-theme

They were replaced by these packages:

  • evolvere-icon-theme-flat-vivid-sunken
  • evolvere-icon-theme-flat-vivid-sunken-dark

During this update the entry for the solydxk repository in the /etc/apt/sources.list file will be changed to:

deb solydxk-8 main upstream import


This will prevent your system to automatically upgrade to Debian Stretch when we switch the default SolydXK repository from solydxk-8 to solydxk-9 for Stretch. You can decide whenever you are ready for the upgrade by simply changing the sources.list file. We will provide a howto when that time comes.

As you can see we created the next stable SolydXK repository called solydxk-9. This repository will contain the same files as our current solydxk-8 repository but with some specific packages added for the next release based on Debian Stretch. I’ve recently started a topic on our forum where people can try out the alpha releases of these ISOs. They are under heavy development and by far ready from being used as a production system but if you want to have a peek on what’s coming next and want to help out debugging, here’s the link:
