Cause

This error occurs when Bitbucket doesn't have read-write permission inside <Bitbucket-Home-Directory>/caches/pack/ directory.

Solution

Make sure the Operating system user who is running the Bitbucket process has read, write, and execute in <Bitbucket-Home-Directory>/caches/pack/ and all of its subdirectories.
