I’m trying to restore my files from a previous Nextcloud instance (which has worked before) using this command:

sudo -u www-data php /var/www/nextcloud/occ files:scan --all

However, no matter what solution I implement, I get this error most of the time:

OCP\HintException: [0]: Memcache \OC\Memcache\APCu not available for local cache (Is the matching PHP module installed and enabled?)

I try to run the following code that many say fixes the problem, but I get all of this in response:

sudo -u www-data php --define apc.enable_cli=1  /var/www/nextcloud/occ  maintenance:repair

An unhandled exception has been thrown:

I have php8.0-apcu installed, but maybe I need to install something else…? Ngl, I’m a bit of a novice to server maintenance (especially this), but I’m a moderate Ubuntu user. I’m more than willing to walk through anything I’ve already setup/installed/configured. Any advice or help is greatly appreciated.

I have the same issue with PHP8.0-apcu. Tried adding apc.enable_cli=1 to /etc/php/8.0/apache2/php.ini, /etc/php/8.0/cli/php.ini and /etc/php/8.0/mods-available/apcu.ini.

Even adding apc.shm_size=512M to /etc/php/8.0/mods-available/apcu.ini still no luck…

Some other posts suggest going to an earlier version of php, but I will wait for a solution for php8.0

Update (2 mins later):

sudo -u www-data php8.0 --define apc.enable_cli=1  /var/www/nextcloud/occ  maintenance:repair

Worked!

I actually tried it again using the latest PHP version (8.1) along with the latest version of NC (24.0.2) and it worked ok for me. I still had to add that one line in the cli/php.ini file. All good now!

Solution in my case php-cli and php-fpm version did not match.
Check /etc/apache2/conf-enabled/php*-fpm with update-alternatives --config php output
