Hello Everyone,
Building my own LibreNMS+Oxidized install has been my attempt to clean some rust off some very old linux skills I haven’t flexed in many years. Its a learning exercise for me, but slugging through it has been extremely rewarding.

Once I got LibreNMS + Oxidized up and running, I was feeling pretty good. Then I wondered “how do I keep oxidized up to date” and read somewhere to run “gem update”. Anyways, that ran for a very long time and updated a whole bunch of stuff I don’t think I even had or needed and now both web interfaces are down and my validate.php looks like i’ve destroyed whatever I built.

Validate PHP and whatever I could copy from the gem update below

librenms@LibreNMS:~$ ./validate.php

Try something like
php artisan optimize:clear
./scripts/composer_wrapper.php install --no-dev
./daily.sh
Thanks for responding Jellyfrog.  Sorry but I’m really new to this - I tried your first command and it didn’t come back so well…

Youre running at root, which the docs, the validator-script and other places says you really shouldn’t.

And you didnt run the rest of the commands
