gpg: no valid OpenPGP data found. When installing Cassandra on Docker on Linux Lite

Question

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.

Solution

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.

Thanks, but unfortunately it doesn't work for me. I know it depends on the version of python installed. I have version 2.7.17. If I had 2.5.15 or earlier I wouldn't have a problem turning on cqlsh
