Why doesn't capistrano deploy work?

Question

Ruby on Rails

When deploying, it gives an error:
* executing "cp -RPp /home/app/production/shared/cached-copy /home/app/production/releases/20171019060907 && (e3f8f140652b3f1a6b6065b442f29d13646c3e70 > /home/app/production/releases/2017101907 > /home/app/production/releases/2017101907 )"

It is clearly written:
Give permission to the directory.
