Fixing Raspberry Pi OS Issues After 'Failed to Fetch' Error

When using a Raspberry Pi, it's not uncommon to encounter issues with booting after updating or upgrading the system. One such issue is when the system fails to fetch updates from the internet, resulting in a failed update and subsequent inability to boot. In this article, we'll explore one such experience and how to resolve it.

The Issue

I recently encountered an issue with my Raspberry Pi 4, running OpenHAB version 3.3.0-SNAPSHOT (Build #2785). After updating the system using `sudo apt update` and then attempting to upgrade, I received a 'Failed to fetch' error message. Despite trying various troubleshooting methods, including restarting the device, the issue persisted.

The Solution

In my case, I made an unexpected mistake by using a hard disk drive (HDD) instead of an SD card as the boot device. Although I didn't think it would matter since the Pi natively boots from USB, it turned out to be the culprit. After switching back to the original SD card, I was able to successfully update and upgrade my system.

1. Be mindful of hardware changes: When making changes to your Raspberry Pi setup, ensure you're aware of any potential implications on the system.

2. Check for software requirements: Before attempting to attach new hardware, verify that it doesn't require software or configuration changes on the OS part of openHABian.

In conclusion, when encountering issues with booting after updating or upgrading your Raspberry Pi, be sure to check any recent hardware changes and ensure you're using the recommended storage device. If you're still experiencing difficulties, consider seeking help from a Linux expert or trying alternative troubleshooting methods.
