Problem with YARA

[HugoBertrand]

Hello,

I have some problems with Yara scan. When I run the scan with a ruleset on a path, I only get scan errors in response, including "error 4" or "could not open file". I don't know why
However, I run the 'deploy.sh' file with root rights.
If you can tell me how to fix this problem, that would be very nice.

Thank you in advance.
