Internal Server Error After Adding New App

Hello All

I installed the latest stable version on Linux mint and had everything working perfect.
I disabled the Recommendations app and tried to add a few ones. It seems like the recommendations app disabled properly but I got a error message for the others.

After refreshing the web browser i have error:

Internal Server Error

The server was unable to complete your request.

*** Remote Address: (my external ip address from my desktop)**
*** Request ID: PMGZ9brSls7rj1DWfIoE**

When i look in my data directory in the nextcloud log i see the following.

Anyone have ideas? Is it possible to disable the apps from terminal or run nextcloud in a safemode with all third party apps disabled?

Thanks in advance

You can disable apps using the occ command, which you will find in the Nextcloud document root directory.

SQLSTATE[42S02]: Base table or view not found: 1146 Table ‘nextcloud.oc_external_mounts’ doesn’t exist"
I think the main problem on your system is a missing “oc_external_mounts” table. Try to create the table manually and check if the problem has been fixed afterwards. This is how the table looks no Nextcloud 18.0.4:

MariaDB [nextcloud]> describe oc_external_mounts;
| Field           | Type         | Null | Key | Default | Extra          |
| mount_id        | bigint(20)   | NO   | PRI | NULL    | auto_increment |
| mount_point     | varchar(128) | NO   |     | NULL    |                |
| storage_backend | varchar(64)  | NO   |     | NULL    |                |
| auth_backend    | varchar(64)  | NO   |     | NULL    |                |
| priority        | int(11)      | NO   |     | 100     |                |
| type            | int(11)      | NO   |     | NULL    |                |

Thanks for your response. Can you please tell me how to create this table?

I use “sudo mysql -u root -p” to connect to db then what is the next steps? I cannot find any detailed info online how to add a table to mariadb.

Thanks in advance

As usual aunt G. knows the database basics :wink:
