Hi @kuker
This is an issue recently reported. To fix it you will need to edit as root /etc/apt/sources.list and comment out (#) the two lines…
# deb https://deb.parrot.sh/parrot/ lory non-free contrib main
# deb-src https://deb.parrot.sh/parrot/ lory non-free contrib main
It looks like /etc/apt/sources.list.d/parrot.list is now preferred.
