I am trying to install Cassandra on Ubuntu 16.04 64-bit machine. This requires adding keys to Cassandra repository. A step requires me to do the following:
curl https://www.apache.org/dist/cassandra/KEYS | sudo apt-key add -
But I'm facing the error:
curl: (7) Failed to connect to www.apache.org port 443: No route to host
gpg: no valid OpenPGP data found.
I tried looking for answers but there weren't any related to my issue, please help.
