Permissions error on Doctrine\Inflector package

For whatever reason, during deployment I receive a strange error during the Finalize the deploy task:

Permission denied: '/srv/www/website-url.com/releas
es/20180514225131/web/app/themes/sage/vendor/doctrine/inflector/LICENSE'

The deployment works fine, but just wanted to bring this up in case it would help solve another problem later. Thanks!

Thanks, Ben. I will check that out. I never altered permissions on the remote server and they appear to belong to the correct group. No harm, no foul. Sorry for spammy posts but I am about to post an issue with Sage 9.
