Error discovering fdb-table module
The problem
Error discovering fdb-table module. Check log file for more details.

[FAIL] python3 not found
[FIX]:
Install Python 3 for your system.
The python error is not true, its because FreeBSD does not link python3 to python3.X. If someone can point me to the code where the python detection is done I'll create a PR.
What was the last working version of LibreNMS?
21.5.1
Anything in the logs that might be useful for us?
I'm running FreeBSD 13-STABLE if that's relevant.
Seems like something odd with your install.
what is the output of lnms config:get install_dir
root@librenms:/usr/local/www/librenms # su -m www -c "./lnms config:get install_dir" /usr/local/www/librenms
I can't figure out what your error means.
[2022-03-11T13:00:03.629126+01:00] production.ERROR: Error discovering fdb-table module for localhost. Illegal offset type #0 /usr/local/www/librenms/includes/discovery/fdb-table.inc.php(29): include()
Line 29 of that file is an include, which is consistent with the error, but illegal offset is usually when you try to use null for an array key or something, which isn't really on that line.
I can't decipher or reproduce your issue, so I'm afraid I can't help you.
Is there a way I can run this discovery from the CLI? (maybe its more verbose with errors?)
Does this help in any way?
