Hi everyone, I followed the wiki debian packaging to try it
When server connects to the Internet through a proxy, It's possible to have an other error when adding publickey (gpg --keyserver pgp.mit.edu --recv-keys F758CE318D77295D) the error is like that : gpg: requesting key 8D77295D from hkp server pgp.mit.edu gpgkeys: HTTP fetch error 7: couldn't connect to host gpg: no valid OpenPGP data found. gpg: Total number processed: 0 Simply, It's because the proxy is not set, To correct the problem, you must set the environment variable http_proxy. It could be interesting to add this on the wiki to help even more users when installing cassandra through debian packaging. regards, Jérémy
