Assuming you trust Michal Papis import the mpapis public key (downloading the signatures). We will use the gpg program to check the signatures. In the guide to verifying the ISO on the Linux Mint website it does say "Note: Unless you trusted this signature in the past, or a signature which trusted it, GPG should warn you that the signature is not trusted.
