Yup, I'm aware of that, gpg key expired this morning.
Working on that...

I think it's resolved now for NEW installations.

However, for old servers - they need to run this in SSH:

wget https://apt.myvestacp.com/deb_signing.key -O deb_signing.key
sudo apt-key add deb_signing.key
sudo apt-get update
