Kicksecure stable / testers / developers APT Repository. How to change from one suite to another? How to disable Kicksecure APT Repository?

Kicksecure APT Repository Overview[edit]

Kicksecure currently provides four repository choices:

  • Kicksecure stable APT repository: Recommended for most users. The production level packages focus on providing the most reliable Kicksecure experience. [1]
  • Kicksecure stable-proposed-updates APT repository: After testing by a wider audience, these packages migrate to the stable repository. [2]
  • Kicksecure testers APT repository: Recommended for testers, since it is only briefly tested by Kicksecure developers. It could break APT during an upgrade, requiring terminal commands to rectify the problem. [2]
  • Kicksecure developers APT repository: As above, except it includes untested changes. These changes may eventually migrate to the testers repository there is reasonable certainty that these changes will not break the update system. It is not recommended, unless the user is in touch with the development team.

Due to the Kicksecure design, a user's security is unlikely to be materially affected by preferring the "beta" (stable-proposed-updates) or "alpha" (testers) repositories over the default stable one. [3]

Onionizing Repository[edit]

This is not yet possible with the GUI. Only with the CLI.

See Onionize derivative.list.

Disable Kicksecure APT Repository[edit]

For Trust reasons some users may prefer not to use Kicksecure APT Repository. In that case, it is necessary to update Debian packages in Kicksecure from source code, which is inconvenient.

All Default-Download-Version Kicksecure variants have the Kicksecure APT repository enabled. It can be disabled via the GUI or in a terminal with the Derivative Repository Tool.

Table: Kicksecure APT Repository Disabling

Platform / Method Instructions
Kicksecure Built from Source Code If Kicksecure is built from source code, Kicksecure APT Repository is not added by default. The only exception is if users opt in using a build configuration. It is also possible to verify that it is already disabled.
Kicksecure Default-Download-Version: GUI
  • Kicksecure-Qubes: Qubes App Launcher (blue/grey "Q")Template: kicksecureRepository"No, I will manually update from source code."
  • Kicksecure: Start MenuApplicationsSystemKicksecure Repository"No, I will manually update from source code."
Kicksecure Default-Download-Version: Terminal To disable it in a terminal, run.

sudo repository-dist --disable

Users can optionally verify Kicksecure APT repository is disabled after this procedure.

Verify Kicksecure APT Repository is Disabled[edit]

To check the Kicksecure APT repository was successfully disabled, run the following tests.

1. Use apt-key.

sudo apt-key finger

This test should not show any Kicksecure-specific keys, such as Patrick Schleizer's OpenPGP key.

2. Check if file /etc/apt/sources.list.d/derivative.list exists.

If it does not exist, the procedure was successful.

3. Optional: conduct additional tests as a precaution.

Examine the /etc/apt/sources.list file. It should not include the Kicksecure APT Repository.

cat /etc/apt/sources.list

Next examine the /etc/apt/sources.list.d/ folder as well.

cat /etc/apt/sources.list.d/*

Further Reading[edit]


  1. If possible, users are requested to run a separate testers-only Kicksecure that has the testers repository enabled. If too few people test Kicksecure, undiscovered issues might migrate to the stable repository.
  2. 2.0 2.1 Users are recommended to make a VM clone for this repository just in case it breaks. That way changes can be rolled back if necessary.
  3. The terms alpha and beta are avoided because they have generally lost their meaning in the software field; many applications remain in alpha or beta status for years, even though they work perfectly well.
