IDE hangs on startup: "discovery builtin:serial-discovery not found"

[Violettica]

Describe the problem

The Arduino IDE appears to not be able to use its Arduino CLI backend properly at all, yet using the CLI directly doing equivalent operations appears to get results.

To reproduce

1. Start a fresh install of Arduino IDE which updates the index. Eq. CLI: arduino-cli update
2. Do nothing and wait for the Arduino_Builtin library to install. Eq. CLI: arduino-cli lib install Arduino_Builtin
3. Install the Arduino AVR board core. Eq. CLI: arduino-cli core install arduino:avr

Expected behavior

In every step of the reproduction, the IDE fails to do these operations and it's required to stop the IDE process and run the CLI equivalents marked before starting the IDE again to make progress.
Symptoms shown are as follows, corresponding to each step:

1. On start-up, hangs forever. Logs show "network unreachable" error. CLI seems to be able to reach the network just fine, though, so logically there is no problem with my network.
2. Arduino_Builtin installation error shown. Network unreachable again.
3. AVR installer cannot reach network. Network unreachable.

Arduino IDE version

2.3.3-nightly-20240630

Operating system

Linux

Operating system version

Garuda Linux Hyprland Edition

Additional context

CLI testing done with 1.0.3-1 from Arch Linux extra repo.

Issue checklist

• I searched for previous reports in the issue tracker
• I verified the problem still occurs when using the latest nightly build
• My report contains all necessary details

Hi @Violettica. Thanks for your report.

Logs show "network unreachable" error.

Please add a comment here that provides the Arduino IDE logs.

You are welcome to collect them via whatever procedure is most convenient. I'll provide instructions for collecting them from the terminal:

---

❗ This procedure is not intended to solve the problem. The purpose is to gather more information.

---

Please do this:

1. Close all Arduino IDE windows if the IDE is already running.
2. Open a command line terminal in the folder that contains the Arduino IDE installation.
3. Invoke the Arduino IDE executable.
   For example, if you are using the "AppImage" package, the invocation would look like this:

   ./arduino-ide_<version>_Linux_64bit.AppImage
   

   (where <version> is the Arduino IDE version number)
   Or if you are using the ZIP package, the invocation would look like this:

   ./arduino-ide
   

   Debug output should now be printed to the PowerShell window as Arduino IDE starts (or fails to start).
4. Wait for Arduino IDE to finish starting, or failing to start.
5. Switch back to the terminal window if the Arduino IDE window took the focus.
6. Use the mouse to select all the text in the terminal window. Make sure to scroll all the way up to the top.
7. Press the Ctrl+Shift+C keyboard shortcut to copy the selected text to the clipboard.
8. Paste (Ctrl+V) the copied output in a reply to this GitHub issue thread.

---

Please let me know if you have any questions or problems while following those instructions.

Sure thing. Here's what the logs look like on nightly AppImage after deleting .arduino15 and .arduinoIDE, I believe this creates a "fresh install" environment. This shows the "endless hanging" behavior described in Step 1.

Need logs for the other steps too?

Interesting, I just reviewed the log and I was incorrect about it having "network unreachable" log text on nightly. Unlike Arch Linux extra's version, nightly seems to have a different log with the same application behavior on fresh install startup. I have confirmed that all the reproduction steps still have the same behavior on nightly. I can provide logs for the stable version if that's of interest.
