Permissions Fail

Hi, I’m trying to migrate a website with the plugin Duplicator. I could build the files, but when I’m going to start the Deployment (Step 1), I’m unable to continue, it says Permissions Fail.
I don’t understand why is this happening, I have grant all privilleges to the /var/www folder (chmod 777) to apache, but it still doesn’t work.

Any idea why is this happening?

Thanks in advance!
