Installing Jellyfin Using Podman

I'm having issues following the instructions for installing Jellyfin with Podman (the Ubuntu/Debian packaging instructions do not work with Trisquel.)

https://jellyfin.org/docs/general/installation/container#managing-via-systemd

Steps to reproduce:

$ sudo apt install podman
$ podman run \
--detach \
--label "io.containers.autoupdate=registry" \
--name myjellyfin \
--publish 8096:8096/tcp \
--rm \
--user $(id -u):$(id -g) \
--userns keep-id \
--volume jellyfin-cache:/cache:Z \
--volume jellyfin-config:/config:Z \
--mount type=bind,source=/home/caleb/media,destination=/media,ro=true,relabel=private \
docker.io/jellyfin/jellyfin:latest


Go to farnsworth:8096 in a web browser and follow the instructions.

$ sudo useradd jellyfin
$ loginctl enable-linger jellyfin


Here's where I have an issue:

$ machinectl shell jellyfin@
-bash: machinectl: command not found

I don't know how to proceed.
