These are my notes on installing Nextcloud on Raspberry Pi and getting a green checkmark on the Administration Overview page.
My last installation is in '00. Nextcloud 25.0.4 on Raspberry Pi 4 running Bullseye, mysql, apache and Let's Encrypt certificate'.
All solutions to the issues I had right after finishing the installation are in that document.
Issues solved during upgrades and previous installations are in other documents in the old notes folder.
Current version Nextcloud is 29.0.0
