WHY NEXTCLOUD, WHY DOES IT HAVE TO BE SO FUCKING COMPLICATED TO UPGRADE YOU TO THE LATEST VERSION??????

NOT ONLY DID THE DATABASE MIGRATIONS NOT RUN, YOU DIDN'T HAVE THE UPDATED VERSION OF THE FUCKING AUTHENTICATTION PROCESSOR IN THE OFFICIAL SERVER DOWNLOAD SO THE WHOLE THING WAS BROKEN AFTERWARDS.

I'VE WASTED 4 HOURS ON THIS FUCKING UPGRADE 😤😤😤😤😤😤😤

Nah, it's actually quite straight-forward.
Assuming /var/www/nextcloud is where Nextcloud is located:

#First, kill your webserver
cd /var/www
mv nextcloud nextcloud-old
wget <nextcloud zip link>
unzip <nextcloud zip file name>
rm nextcloud*.zip
cp nextcloud-old/config/config.php nextcloud/config/config.php
# If your data is stored in the default folder, uncomment the line below
# cp -r nextcloud-old/data nextcloud/data
cp -rf nextcloud-old/apps/ nextcloud/apps/
sudo -u www-data php -f /var/www/nextcloud/occ upgrade
#Start the web server again

@filthyranter Thats kind of what I did, except I'm running nextcloud with docker.

And the migrations didn't run...........

And then this happended: https://github.com/nextcloud/...

I'm currently trying to run nextcloud behind a nginx reverse proxy in my LAN but I can't get fpm to accept requests. Any suggestions?

@ThermalCube You need to allow the reverse proxy in the config
