Also got problems with the web updater.
Running Nextcloud 14.0.3 on a FreeNAS-11.2-RELEASE-U1 I did a upgrade via the freenas shell.
iocage upgrade nextcloud
This worked fine, but now i got stuck in the webupater.
Possible CSRF attack. Connection will be closed.

Then I switched to shell, having more issues:
root@nextcloud:/usr/local/www/nextcloud # chmod +x occ
root@nextcloud:/usr/local/www/nextcloud # ./occ upgrade
Console has to be executed with the user that owns the file config/config.php Current user: root Owner of config.php: www Try adding 'sudo -u www ’ to the beginning of the command (without the single quotes)
root@nextcloud:/usr/local/www/nextcloud # su www ./occ upgrade
This account is currently not available.
Any suggestions? I don’t want to change to much via the shell and also don’t want to change the owsership of the config.php because it might break even more stuff!
On the Internet I found nothing usefull…
