Failed to fetch version from local git: fatal: detected dubious ownership in repository at '/opt/librenms'

Help

Hi,
the validate output of my LibreNMS shows no errors:

librenms@srv-librenms:~$ ./validate.php

Component Version
LibreNMS 26.9.0-dev.73+9f526a5604 (2026-09-04T17:22:32+02:00)

Instead the web validation show this error:

FAIL: Failed to fetch version from local git: fatal: detected dubious ownership in repository at ‘/opt/librenms’ To add an exception for this directory, call: git config --global --add safe.directory /opt/librenms

The command

git config --global --add safe.directory /opt/librenms

had no effect

Any suggest? Is it correct that the 2 validation have different result?

Thanks

It is important that you run the check as the same owner of the directory.
If daily is called by a different user, then the directory should also be owned by that user for everything to just work.

Which user are you running this as, and who is the user of . (ls -la)

I run validate.php with user librenms

The owner of the folder is librenms

The problem is that validate.php and web validation have different result

librenms@srv-librenms:~$ ./validate.php

Something has probably at some time run the daily as a different user, ls -la /opt/librenms output?

So both . And .git has correct ownership, and you are running as this user.
Check the contents of .git for anything not having correct ownership, or just replace the ownership.

If still fails, check /etc/passwd if you somehow have multiple users that is confusingly similar in name.
