NO_PUBKEY on intell error

[adamgallub22]

After downlaoding kaldi and following the steps I came across a NO_PUBKEY error when trying to install mkl. I have an intel processor which may be the reason for this issue. The following lines are the screen display with my issue. I came here to find an answer.
sudo ./install_mkl.sh
./install_mkl.sh: Your system is using debian-style package management.
