Validate.php - updated_at wrong schema

Hello, I*m new to LibreNMS and did a new, clean installation.

./validate.php brings the following error message:

Component Version

PHP 7.0.15-0ubuntu0.16.04.4

[OK] Database connection successful
[FAIL] Database: incorrect column (users/updated_at)
[FAIL] We have detected that your database schema may be wrong, please report the following to us on IRC or the community site (
ALTER TABLE users CHANGE updated_at updated_at timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP;
[WARN] You have not added any devices yet.

Could you please tell me what to do? Server is a new Ubuntu 16.04.02 LTS.

Thank you.

The first thing would be to read the message in the output :slight_smile: It tells you where to post for that specific FAIL.

However, you can run that ALTER statement in mysql safely.

Thank you very much for your quick response. The database error is fixed/gone by the given input.

Now I’ve got:

[WARN] Your install is out of date, last update: Thu, 06 Apr 2017 21:02:37 +0000

If you are just on normal daily updates that’s to be expected, you can update by running ./

Thank you very much. Everything is fine now.
