Migration from snap not working

Hi guys,

Is your feature request related to a problem? Please describe.

Yes, I am trying to migrate a snap installation to Nextcloud-AIO but I'm facing multiple issues when following the documentation to the letter.

Describe the solution you'd like

I'd like the documentation to work.

Additional context

• At step 10, when running this command : sudo docker exec -i mysql-migration mysql -u nextcloud -p"$MYSQL_PASSWORD" nextcloud < ~/mysql-dump.sql I get the following error (even when starting container with --skip-log-bin) : ERROR 1227 (42000) at line 2353: Access denied; you need (at least one of) the SUPER or SET_ANY_DEFINER privilege(s) for this operation

  The workaround I found is to import as root but I am not sure this is the best method.

• At step 13, when running the last command : sudo docker exec -u www-data nextcloud-convert php occ db:convert-type --all-apps --password "$PG_PASSWORD" pgsql "$PG_USER" postgres-migration "$PG_DATABASE"

  I get the following error :

  Console has to be executed with the user that owns the file config/config.php Current user id: 33 Owner id of config.php: 1000 Try adding 'sudo -u #1000' to the beginning of the command (without the single quotes) If running with 'docker exec' try adding the option '-u 1000' to the docker command (without the single quotes)

  The workaround I found : sudo chown 33:33 /tmp/migration-config.php

  But then :

    Your data directory is not writable.
    Permissions can usually be fixed by giving the web server write access to the root directory. See https://docs.nextcloud.com/server/33/go.php?to=admin-dir_permissions.

    An unhandled exception has been thrown:
    Exception: Environment not properly prepared. in /var/www/html/lib/private/Console/Application.php:143
    Stack trace:
    #0 /var/www/html/console.php(86): OC\Console\Application->loadCommands(Object(Symfony\Component\Console\Input\ArgvInput), Object(Symfony\Component\Console\Output\ConsoleOutput))
    #1 /var/www/html/occ(33): require_once('/var/www/html/c...')

The workaround I found : sudo chown -R 33:33 /var/snap/nextcloud/com mon/nextcloud/data. Also had to to chown 33:33 the config/ folder inside the container

Then when I could finally run the migration command :

In Config.php line 273:
                                                                                            
  Configuration was not read or initialized correctly, not overwriting /var/www/html/confi  
  g/config.php

I didn't find any workaround for this one.

Is it possible to fix the documentation?

Thank you guys!
