quick fix for me needing smbclient for my hosted nextcloud instance, so i can add my NAS shares to it.
Link to original Repo -> https://github.com/nextcloud/docker
$ docker pull ghcr.io/bym0/nextcloud-smb:latest
following packages are installed onto the nextcloud:latest base image
- procps
- smbclient
