This seems to be a permissions issue. I believe the owner of the files contained in your PyfDownloadTool directory does not match the user on your terminal.
You can verify that by running ls -l. Check if the user listed as owner for the files matches the same user returned by whoami.
In case those differ from each other, you'll want to make changes so they match.
To update the files permissions owner to match the current user in the terminal, run:
sudo chown -R $(whoami) .
If the user returned by $whomai differs from what you expect (maybe you're accessing it as root?), change it to the proper user:
sudo su - <username>
