# Permission denied error for monero-blockchain-blackball

I'm attempting to run the monero-blockchain-blackball utility in PureOS, and I'm running into a permission error.

I used the syntax to select the tool, then the Monero blockchain, then a forked blockchain (I'm using Monero v6 for testing). The syntax is described here.

Upon running the command, I receive the following text:

I deleted the /.shared-ringdb folder, but the error persists.

How can I fix this permission error?
