# Repairing Nextcloud
You can run the maintenance commands like this:
```
sudo -u nextcloud nextcloud-occ maintenance:mode --on
sudo -u nextcloud nextcloud-occ maintenance:repair
sudo -u nextcloud nextcloud-occ maintenance:mode --off
```
Converting from SQLite to MySQL (mariadb)
First: keep Nextcloud set to SQLite as its dbtype, and separately launch MySQL
as a service by copying the configuration found
[here](https://github.com/NixOS/nixpkgs/blob/nixos-unstable/nixos/modules/services/web-apps/nextcloud.nix).
No password is necessary, since the user-based auth works with UNIX sockets.
You can connect to the MySQL instance like this:
```
sudo -u nextcloud mysql -S /run/mysqld/mysqld.sock
```
Create a blank database for Nextcloud:
```sql
create database nextcloud;
```
Now setup the [conversion](https://docs.nextcloud.com/server/17/admin_manual/configuration_database/db_conversion.html):
```
sudo -u nextcloud nextcloud-occ db:convert-type mysql nextcloud localhost nextcloud
```
Ignore the password prompt. Proceed with the conversion.
Now `config.php` will be updated but the override config from NixOS will not
be. Now update your NixOS configuration:
- Remove the `mysql` service you created.
- Set `dbtype` to `mysql`.
- Set `database.createLocally` to `true`.
Rebuild your configuration.
