When installing Cassandra on Docker on Linux Lite after entering:
curl https://www.apache.org/dist/cassandra/KEYS | sudo apt-key add -
then I get:
gpg: no valid OpenPGP data found.

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.
