Updates:
After searching a bit, I have used the below commands to fix it:

sudo mkdir -p /root/.gnupg
sudo gpg --no-default-keyring --keyring /etc/apt/keyrings/mysterium.gpg --keyserver keyserver.ubuntu.com --recv-keys ECCB6A56B22C536D

Now after running:
sudo -E bash -c "$(curl -s https://raw.githubusercontent.com/mysteriumnetwork/node/master/install.sh)"

I am getting this now:

Looks like the commands used internally uses apt-key command which is already not available in apt.
