I seriously suggest you give Nextcloud another go, this time under Docker. Very simple to do.

Save the following in a new folder as docker-compose.yml

version: '3'

volumes:
  db:

services:

  nextcloud-app:
    image: nextcloud
    container_name: nextcloud-app
    restart: always
    volumes:
      - ./data:/var/www/html
    environment:
      - MYSQL_PASSWORD=changeme
      - MYSQL_DATABASE=nextcloud
      - MYSQL_USER=nextcloud
      - MYSQL_HOST=nextcloud-db
    ports:
      - "80:80"
    links:
      - nextcloud-db

  nextcloud-db:
    image: mariadb
    container_name: nextcloud-db
    restart: always
    command: --transaction-isolation=READ-COMMITTED --binlog-format=ROW
    volumes:
      - db:/var/lib/mysql
    environment:
      - MYSQL_ROOT_PASSWORD=changeme
      - MYSQL_PASSWORD=changeme
      - MYSQL_DATABASE=nextcloud
      - MYSQL_USER=nextcloud

run this command in the folder -

docker-compose up -d

open http://localhost
