Error: No public key found at the given path

Installation Issues
1

Dear passbolt, i cannot pinpoint the origin od this issue but during installation i get the error:
No public key found at the given path /var/www/passbolt/app/ConfigConfig/gpg/serverkey.asc

As you can see /ConfigConfig/ is written twice. How would i be able to fix this?

Best regards,
Dragan

EDIT RESOLVED: Fount a mistake in my app.php where config part was written twice.:
‘public’ => APP . ‘Config’ . DS . ‘gpg’ . DS . ‘serverkey.asc’,
