Upgrading old release: how to ask installed version

hello,

after resolving a bug with an old install, nextcloud home page says i’m using an old version (maybe 11 or 12) and that i have to upgrade manually

but i don’t remember which version is installed, the server says i have to upgrade version 13.0.6

is there a tool to view installed (i already tried localhost/version.php with a blank page result)

thanks

You can try

sudo -u www-data php /var/www/nextcloud/occ upgrade -V

or login as administrator and follow the menu settings

Go to settings -> Overview

    My install is version 14.0.3 (update channel "stable")
