I got an error like this same issue. I was also getting the gpg: no valid OpenPGP data found. error. So I changed the URL a bit because I discovered it wasn't pointing to the exact gpg file.

curl -fsSL https://download.docker.com/linux/ubuntu | sudo apt-key add -

to this

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

and I got 'OK' as output.

I also got the same issue. Actually this URL return 404 when executed so I tried this URL in browser https://www.apache.org/dist/cassandra/KEYS and it is redirected to this URL https://downloads.apache.org/cassandra/KEYS.

So, I changed the URL in the command

curl https://www.apache.org/dist/cassandra/KEYS | sudo apt-key add -

to this

curl https://downloads.apache.org/cassandra/KEYS | sudo apt-key add -

and it worked.

I got this error in an Docker container. I believe the cause was that the container was missing CA certs.

apt-get update

apt-get install ca-certificates
