Default repository no longer signed

Briefly describe your issue below:

So I just freshly reinstalled ParrotSec, and now i’m attempting to reinstall all the programs I had on my system prior to the reinstallation, and while trying to install the Linux friendly steam client, it’s saying that i’m missing, and after attempting to update and upgrade apt, it’s saying that the default repository is “no longer signed” and updating from the repository cannot be done safely.

What version of Parrot are you running? Parrot Security OS 4.4

What method did you use to install Parrot? (Debian Standard

Configured to multiboot with other systems? No

you messed up the repo somehow. did you install the dependency lib/how did you do it?

I dont mean to intrude, but i had the exact same problem, and this fixed my issue:

Hope this helps!
