Hello guys,
My LibreNMS web interface has suddenly stopped working. I realized about this yesterday and looked for a solution online. I’ve followed some indications that were given to some other users with the same symptoms than me, so I validated my installation:
root@lnms:/opt/librenms(LAB)# ./validate.php
| Component | Version |
|---|---|
| LibreNMS | 1.43-81-g57b16c77b |
| DB Schema | ? |
| PHP | 7.0.30-0+deb9u1 |
| MySQL | ? |
| RRDTool | 1.6.0 |
| SNMP | NET-SNMP 5.7.3 |

[FAIL] Missing dependencies! [FIX] ./scripts/composer_wrapper.php install --no-dev
fideloper/proxy
[FAIL] Outdated dependencies [FIX] ./scripts/composer_wrapper.php install --no-dev
psy/psysh
[OK] Composer Version: 1.7.2
[FAIL] Missing dependencies!
[FIX] composer install --no-dev
Dependencies:
fideloper/proxy
root@lnms:/opt/librenms(LAB)#
Then I thought the installation got corrupted during an update, so I ran ./scripts/composer_wrapper.php install --no-dev, as indicated.
root@lnms:/opt/librenms(LAB)# ./scripts/composer_wrapper.php install --no-dev
Do not run Composer as root/super user! See https://getcomposer.org/root for details

The compiled services file has been removed.
Then set the permissions again…
root@lnms:/opt/librenms(LAB)# chown -R librenms:librenms /opt/librenms
And ran validate again…
root@lnms:/opt/librenms(LAB)# ./validate.php

At this point, the HTTP Error 500 got fixed and I was able to get to the Login page, but after authentication I received a funny pacman ghost hiding an exception.
This is the chunk of logs being written everytime I press F5.

I tried to navigate to “/devices/”, tried adding “/debug=yes/” at the end of the URL, but always got the same screen.
I went through the search button looking for “http error 500”. Found some threads but non of them seemed to fit into my situation.
What can I do from here?
