我最近开始在提供商托管的 Ubuntu 机器上使用 Nextcloud 托管我自己的云。昨天我想对配置进行更改，但注意到管理员帐户已被阻止，因为我最多启用了 3 次尝试，直到用户被阻止。
现在我正在尝试找到一种方法来解除对管理员帐户的阻止。我尝试通过 SSH 访问我的服务器，然后尝试运行 occ 脚本来解除对管理员帐户的阻止，但是我似乎无法正确访问该文件。我正在运行 Ubuntu 18.04.5 LTS：
sudo -u www-data php /var/lib/docker/volumes/nextcloud/_data/occ
Could not open input file: /var/lib/docker/volumes/nextcloud/_data/occ
/var/lib/docker/volumes/nextcloud/_data# ./occ user:enable admin
n unhandled exception has been thrown:
Doctrine\DBAL\Exception: Failed to connect to the database: An exception occurred in the driver: could not find driver in /var/lib/docker/volumes/nextcloud/_data/lib/private/DB/Connection.php:85

有谁知道我现在可以尝试什么？
