That isn't an error - you've never connected that Ubuntu system to Bitbucket over SSH, so Ubuntu is confirming that you want to remember Bitbucket in ~/.ssh/known_hosts with that specific key. SSH's default behavior is to compare the contents of known_hosts against the public key provided by a server during the SSH handshake; if the known key doesn't match the provided key then there may be something bad happening.

Bitbucket's public key fingerprints are available at https://confluence.atlassian.com/bitbucket/troubleshoot-ssh-issues-271943403.html?_ga=2.42955813.1074307374.1515452925-758028192.1431549295 and the one in that message matches the RSA key's MD5 hash. You should be safe to click "Yes" here, and you shouldn't see that message again on that system.
