Unclear about adding Sqlite DB to Fly Volume

Yep apk add openssh worked fine in the console thank you. Here is a screenshot of my log once I ran the command.

Now I am at the scp command part of Persistent Volumes/SCPing of Files once I exit the ssh.

My command scp /Users/kakuyonmataeh/assisted_mataeh/assisted.db root@assisted-mataeh.internal:/data/assisted received error “ssh: Could not resolve hostname assisted-mataeh.internal:” nodename nor servname provided, or not known
