Step-by-step Raspberry Pi Update instructions.

These procedures apply to Raspberry Pi 5, 4 or 3 with Raspberry Pi OS (64-Bit), (32-Bit), (Legacy 64-Bit) or (Legacy 32-Bit).

General Notes

1. General: The procedures below are optimized for updating Raspberry Pi 5, 4 or 3 with Raspberry Pi OS (64-Bit), (32-Bit), (Legacy 64-Bit) or (Legacy 32-Bit).

2. Internet access during setup: Many of the steps below assume and require the Raspberry Pi is connected to a network with access to the Internet.

Notice about updates, upgrades and installations failing due to repository or network congestion or outages

Occasionally updates, upgrades and installations fail due to repository or network congestion or outages. Sometimes there is an appropriate message saying as such, sometimes a missing file is reported, and sometimes there is just a failure message without an explanation. When this occurs, simply run the command again. If that does not solve the issues immediately, try again later.
