If you google your exact error "*Host key verification failed."* and it will return what's going on....
https://askubuntu.com/questions/45679/ssh-connection-problem-with-host-key-verification-failed-error The weewx-related answer is that you're using old notes that are still expecting the 'root' user on the weewx system to be the local user, which is no longer accurate. In v5 it is the 'weewx' user (upgrade guide link) <https://www.weewx.com/docs/5.0/upgrade/#weewx-runs-as-non-root-user>. So it is very likely the host key of the remote computer is not known in the /home/weewx/.ssh/known_hosts file. Simplest way around this would be do append whatever is in your legacy /root/.ssh/known_hosts file to your /home/weewx/.ssh/known_hosts file.
