Rclone on 1.16.1

[ostanford]

Should be simple. Working on integration between Kasm and Nextcloud, and need rclone. Any idea what i'm missing?

x@kasm-prod:~$ docker plugin install kasmweb/rclone:latest Error response from daemon: error resolving plugin reference: pull access denied, repository does not exist or may require authorization: server message: insufficient_scope: authorization failed
