"Built-in" examples fail to open

[SuperNinja-4965]

Describe the problem

The Arduino IDE installation includes a collection of "built-in" example sketches that demonstrate fundamental sketch concepts. These are accessed via the "01.Basics" section of the File -> Examples menu.

These "built-in" example sketches fail to open.

The following is shown in the log:

root ERROR Request cloneExample failed with error: Sketch does not exist: [object Object]

I have verified that they do exist.

I have also reset the IDE (and all related folders) to see if that fixes it, it doesn't.

To reproduce

1. Select File -> Examples -> 01.Basics > Blink from the Arduino IDE menus.

🐛 Nothing at all happens. The "Blink" sketch does not open. No error message is shown in the IDE UI.

Expected behavior

New window should open with example.

Arduino IDE version

2.0.1

Operating system

Linux

Operating system version

• Arch Linux

Additional context

The bug does not occur when opening library example sketches or normal sketches.

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

Worth mentioning that the error is reproducible inside and outside of flatpak.

I am facing this is issue as well with latest version of IDE 2.0 available on Arduino website (appimage).
Example cannot be loaded with same error of OP.

Thanks for the report!

I am able to reproduce it and bisected the introduction of the bug to da22f1e / #1333 (does not occur when using the AppImage built from the previous commit 32b70ef

[SuperNinja-4965]

@per1234 you changed my report to add the line:

The bug does not occur when using the ZIP package of the IDE.

but this is incorrect. ALL of my testing was done with the zip package. I never tested with the appimage

[per1234]

Thanks for the correction. For me, opening the "built-in" examples works perfectly when using the ZIP package. However, when using the AppImage package I am able to reproduce the bug.

I am using Ubuntu 20.04

I would suggest that anyone experiencing this bug who is using the AppImage package try the ZIP package as a workaround. Evidently that is not guaranteed to fix it, but it works for me at least.
