Error using the command sudo -u nextcloud php7.3 occ on the nextcloud directory

I am using the nextcloud version 22.1.1~ynh1. I have an permission error when trying to use the occ command

$ cd /var/www/nextcloud
/var/www/nextcloud$ sudo -u nextcloud php7.3 occ list
[sudo] password for admin: 
Sorry, user admin is not allowed to execute '/usr/bin/php7.3 occ' as nextcloud on mydomain.tld.

I also try logged as root

/var/www/nextcloud# sudo -u nextcloud php7.3 occ list
An unhandled exception has been thrown:
OC\HintException: [0]: Memcache \OC\Memcache\APCu not available for local cache (Is the matching PHP module installed and enabled?)

What’s going wrong ? Perhaps I need stop nginx before use this command ?

Well, I found a solution here OCC won't run with memcache/apcu - #7 by Reiner_Nippes - 🚧 Installation - Nextcloud community

I have edit the file /etc/php/7.3/mods-available/apcu.ini adding this line apc.enable_cli=1 and it works (using root)

I discover also this issue here Script et erreur PHP module local cache with another way to resolve the issue editing /etc/php/7.3/cli/php.ini in fact of /etc/php/7.3/mods-available/apcu.ini with the same line

Now the first permissions error is still here, I can’t use the user admin to use occ command…

This seems related to this issue.

Using the modifications to apcu.ini described above, I was able to trigger a scan (as root su’ing as nextcloud, but not as admin.)
Seems like this documentation needs to updated:
https://yunohost.org/oc/app_nextcloud#AddSpace
Near the section where it asks one to scan.
I would do it - but I still got an error: “Home storage for user x not writable Make sure you’re running the scan command only as the user the web server runs as” for most of my users - not sure why.
