Can you check to manually run the following command and let us know the output? The key number is correct, also checked the installer on a testing system - all works as expected.
apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 0xF1656F24C74CD1D8

I think the issue is with dns resolution.
running manually not importing the key
so I set the first line of resolv.conf to " nameserver 1.1.1.1 " instead of my provider nameserver IP and the key was imported. It was installed.
I think it deserves noting it in installation recipe.
Thanks ScIT!

hello, i have the same error without gpg error message on vps debian 9.9 at https://www.leaseweb.com

cat /etc/resolv.conf

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 83.149.80.123
nameserver 85.17.96.69

I don’t know what to do
