Hi @Sonicboom The installation of the " **esp32**" boards platform failed due to timeout occurred during the download. The duration of the timeout that causes Arduino IDE to cancel a download is configurable. You should be able to work around this problem by configuring a higher timeout value. I'll provide instructions you can follow to do that: 1. Select **File \> Quit** from the Arduino IDE menus if it is running. All Arduino IDE windows will close. 2. Open the file at the following path in any text editor: - **If you are using Linux:** ```plaintext /home//.arduinoIDE/arduino-cli.yaml ``` (where `` is your Linux username) - ❗ The `.arduinoIDE` folder may be hidden by default in your file manager and terminal. - **If you are using macOS:** ```plaintext /Users//.arduinoIDE/arduino-cli.yaml ``` (where `` is your macOS username) - ❗ The `.arduinoIDE` folder is hidden by default. You can make it visible by pressing the **Command** + **Shift** + **.** keyboard shortcut. - **If you are using Windows:** ```plaintext C:\Users\\.arduinoIDE\arduino-cli.yaml ``` (where `` is your Windows username) 3. Add the following content to the `arduino-cli.yaml` file (or replace the existing content if equivalent content is already present in the file): ```yaml network: connection_timeout: 600s ``` **ⓘ** I arbitrarily chose a timeout value of 600 seconds. You can adjust this as needed. 4. Save the file. 5. Start Arduino IDE. Now try installing/updating the " **esp32**" boards platform again, just the same as you did before. Hopefully this time it will be successful. Please let us know if you have any questions or problems while following those instructions. * * * The Arduino developers are tracking the need to adjust the timeout system to avoid spurious failures
