DevToys can’t start on Ubuntu 24.04

DevToys is a collection of essential developer tools packed into a single desktop application. It provides a wide range of utilities, including a color picker, JSON viewer, and various text manipulation tools, all in a user-friendly interface.

Symptoms: When you click on the DevToys icon, nothing happens. If you try to execute it through the terminal using the devtoys command, it throws the following error:

$ devtoys

fish: Job 1, 'devtoys' terminated by signal SIGABRT (Abort)

The issue is that DevToys doesn’t work on Ubuntu 24.04 due to the missing AppArmor bwrap profile. This is because Ubuntu 24.04 has introduced restricted unprivileged user namespaces, and the AppArmor profile for bwrap is not included by default.

As mentioned in this comment (https://github.com/DevToys-app/DevToys/issues/1198#issuecomment-2411370778), the solution is to install the apparmor-profiles package, link the bwrap profile, and load it.

Here are the steps:

sudo apt install apparmor-profiles
sudo ln -s /usr/share/apparmor/extra-profiles/bwrap-userns-restrict /etc/apparmor.d/
sudo apparmor_parser /etc/apparmor.d/bwrap-userns-restrict

After following these steps, DevToys should start working correctly on Ubuntu 24.04.

Pi-Hole and IPV6 – How to make it work?

Im using Pi-Hole with IPV4, recently I discovered my router Xiaomi AX1800 (OpenWRT) supports IPv6, as well as my ISP (A1).

I noticed that I can assign DHCP static IPv4 assignment from the router’s interface, but I can’t do the same for IPv6. That’s why I decided to set a static IPv6 address for the machine running Pi-Hole (Raspberry Pi 2).

There is a short guide on how to do that:

Can I disable the default browser response for Shift-click event?

In the newer browsers, you can distinguish the Shift-click event from a simple click, and disable the default response for Shift-click.

To disable Shift-click, insert the following code in your page’s <HEAD> section:


<script language="JavaScript">
  function mouseDown(e) {
    let shiftPressed=0;
  
    if (document.layers) {
        shiftPressed=(e.modifiers-0>3);
    } else {
      shiftPressed=e.shiftKey;

    if (shiftPressed) {
      return false;
    }
  
    return true;
  }
