Hey, I made an account just to answer your question. You’re using apt-get right? Parrot os has documentation that says you shouldn’t apt-get essentially ever since parrot is a rolling release. Allow me to find the proper link for you, in which it shows you where you can update your sources list. This creates the proper signing key Hash and Key Verification - Parrot Documentation .
For other questions I reccomend you read the entire start guide! I’m fairly new to linux as well, and using apt-get actually broke my parrot os install. Use synaptic to update packages after you add / change to new parrot repos / verify the keys. Good luck, and happpy hacking! Personally I install it as a functional and reasonably secure OS and I add tools as I go and as they suit my needs, coming from the home edition.

(sorry, newbies can’t use more than two links haha)

This message shows that the keys are not available: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY C7B39D0362972489
You can download and import keys using a keyserver, here the one from ubuntu.
