I finally took an evening to get NextCloudPi installed on a Raspberry Pi 5 with a large-ish NVMe drive. This was not a smooth ride. For your pleasure, this is how I got it working.
First, use Jeff Geerling’s guide to get the Pi booting from the NVMe drive.
Second, use this guide to move from Debian networking to systemd-networkd, but do not hold the avahi-daemon package.
Third, run the NextCloudPi curl install script.
Next up – the migration from my old instance. I have 1.5TB of files on a spin disk connected via USB that I need to move to the new NVMe storage – but that is for another night.
For the record – I do love NextCloud and NextCloudPi, so no finger pointing here, just sharing some frustration and how I got around the issue.
