Installation broken after update

Help

After the last update, my installation is broken.
Please note that my installation is running in a FreeBSD 11.1 jail!

[librenms@nd-jail-1 ~]$ ./validate.php

Component Version
LibreNMS 1.39-52-gc664fbe1a
DB Schema 250
PHP 7.1.17
MySQL 10.2.14-MariaDB

SNMP NET-SNMP 5.7.3
====================================

[OK] Composer Version: 1.6.5

[FAIL] The poller () has not completed within the last 5 minutes, check the cron job.
[WARN] IPv6 is disabled on your server, you will not be able to add IPv6 devices.
[WARN] Your local git contains modified files, this could prevent automatic updates.
[FIX] You can fix this with ./scripts/github-remove
Modified Files:

I had to comment out Line 861, as the file ‘/proc/sys/kernel/hostname’ does not exist inside my jails file system.

#$config[‘distributed_poller_name’] = trim(file_get_contents(‘/proc/sys/kernel/hostname’));

I am getting the following errors in my http error log.
Before commenting out the line 861 above, it would also complain about the file being nonexistant aswell.

I tried following the following suggestions without any luck.

Probably worth removing the APP_KEY line then running: php artisan key:generate

Thanks alot!

That kinda led me to the solution.
For some reason i ended up with two base64 encoded keys in my bootstrap/cache/config.php

I still believe that the root cause for this mess was the failure during upgrade, caused by

$config[‘distributed_poller_name’] = trim(file_get_contents(’/proc/sys/kernel/hostname’));

i’d suggest using env(‘hostname -s’) or the likes instead.

Or this will always fail for BSD users inside a jail imho!

Feel free to submit a pull request.

Will this php code work php_uname('n')?

6

yes it does
