Error in certificates while upgrading

I’ve just freshly installed parrot and when i start using
sudo apt update
sudo apt full-upgrade

It show me this error.

The following additional packages will be installed:
  ca-certificates
The following NEW packages will be installed:
  ca-certificates
0 upgraded, 1 newly installed, 0 to remove and 1897 not upgraded.
Need to get 157 kB of archives.
After this operation, 393 kB of additional disk space will be used.
Do you want to continue? [Y/n]

E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

And when i try to import certificates it show me this error.
sudo wget -q -O - https://deb.parrotsec.org/parrot/misc/parrotsec.gpg | gpg --import
gpg: no valid OpenPGP data found.
gpg: Total number processed: 0

Then I used sudo apt -f install ca-certificates
but I can’t install anything via apt as this certificate error is there.
I’ve tried it with both apt and apt-get but no difference.
What should I do?

Are you behind a firewall or something? For example the ducking websense
