When upgrading to LibreNMS 1.53.1, your website will not load. You’ll see a message saying check the logs. There will be nothing useful in the logs. I checked. Nothing.
This is how I fixed the loading issue.
In this post:
- FreeBSD 12.0
- LibreNMS 1.51 running in a jail
- Upgrading to 1.53.1
First attempts
$ cd /usr/local/www/librenms
$ ./validate.php
[ErrorException]

Running as www
OK, let’s run that as www.

Eh? What?
References
Searching around, I found nothing useful.
I found the code in question:
$ grep -r 'Application In Production' * vendor/laravel/framework/src/Illuminate/Console/ConfirmableTrait.php: public function confirmToProceed($warning = 'Application In Production!', $callback = null)
That laravel reference did come up during my search though.
This Whoops, looks like something went wrong. Your database is out of date! was helpful in that it made me think about the www user. It has no shell. The script is asking a question. www can’t reply.
Running as root
Let’s run it as root.
But first: I could have set a shell for www, run this command, then reverted back to the /usr/sbin/nologin shell, but I didn’t. Here is the default for www:
$ grep www /etc/passwd www:*:80:80:World Wide Web Owner:/nonexistent:/usr/sbin/nologin
Instead, I did this:
$ sudo ./lnms migrate ************************************** * Application In Production! * ************************************** Do you really wish to run this command?

A validation is now sane:
$ echo ./validate.php | sudo su -fm www ==================================== Component | Version --------- | ------- LibreNMS | 1.53.1 DB Schema | 2019_05_30_225937_device_groups_rewrite (135) PHP | 7.2.20 MySQL | 5.7.26 RRDTool | 1.7.2 SNMP | NET-SNMP 5.7.3 ==================================== [OK] Installed from package; no Composer required [OK] Database connection successful [OK] Database schema correct [WARN] IPv6 is disabled on your server, you will not be able to add IPv6 devices. $
Ignore that IPv6. I do have it configured. The code is wrong.
Fixed
Now the website loads.
Hope this helps because everyone upgrading needs to know it.
