Upgrading nextcloudpi system from Raspberrypi 3B+ to 4

[anon75456558]

One issue… make sure you are on 64bit raspbian.

Check your architecure with this command on any default Debian/Raspbian/Ubuntu install:
$ dpkg --print-architecture
armhf or arm64

Why am I stuck on armhf and not on arm64?

Raspberry Pi’s have been around for a long time and have been focused on armhf (32-bit) support since day one, all the way up to today on 10/25/2020! Problem is the hardware has advanced well beyond this concept since 2018. armhf Models Pi Zero, 1, 2, 3 arm64 / aarch64 Models Pi 3b+ and all Model 4 varients Big Problem: images provided for installation are still armhf Check your architecure with this command on any default Debian/Raspbian/Ubuntu install: $ dpkg --print-architecture arm…

Moving from armhf (32bit) to arm64 (Pi 4)

Since 2021 all images for the Raspberry Pi on GitHub are arm64 bit images. If you have set up your NCP before late 2020 you quite likely still run a armhf (32 bit) image. This wiki attempts to create a beginner-friendly ‘how-to’ to move from armhf to arm64. You are most welcome to contribute, by commenting and editing this wiki. Why would you want arm64? whole NC development focuses on 64bit so your 32bit NCP limits you in many ways and will do so increasingly. However, before doing th…
