No Access to gui / Symfony parse error

Help
1

Since two days I get this error:
[2019-01-07 08:17:24] production.ERROR: Symfony\Component\Yaml\Exception\ParseException: Unable to parse at line 18 (near “<<<<<<< HEAD”). in /opt/librenms/vendor/symfony/yaml/Parser.php:288
Stack trace:

Access to the webgui is not possible

Is there a knowen code problem or does anybody have an idea for the root cause:
./validate.php is OK:
[root@fh-vm-noc05 librenms]$ ./validate.php

You somehow managed your dependencies in the vendor folder. Delete it and ./composer_wrapper.php install --no-dev

I did it. But the error is not gone:
Also I run ./daily.php

I deleted ./symfony
and installed it again as you described:

librenms@fh-vm-noc05 vendor]$ …/scripts/composer_wrapper.php install --no-dev

Working now?

6

No It doesnt work.
Also I get:
[librenms@fh-vm-noc05 ~]$ ./poller.php
LibreNMS Poller
In poller.php line 24:
Undefined index: h

The problem exists since last saturday. But there were no system changes, even daily.sh
The system didn’T collect any data since two days.

7

You need to specify -h on ./poller.php

8

OK, thanks but the main problem still exists:
no access to GUI and symfony error

9

I run the poller with the -h option.
It started fine but than stopped with:

This seams to be the same error message as in symfony parse error

Oh, I stopped to read your error. your vendor dir is fine.

It says you have invalid yaml format in the file includes/definitions/zynos.yaml

I’m guessing you merged something into your local git master.

git reset --hard origin/master can remove those commits if you want.

11

Ok, that solved my problem.
But what did this exactly. I would like to understand what happend.
Thx a lot for you helping hand and time!

I’m not sure, did you test a PR from github and somehow merge it? Or perhaps made local changes and merged them?
