• systemctl --user daemon-reload

• systemctl --user start guacamole.service

• if fail, check with journalctl --user -xe

• /usr/libexec/podman/quadlet -dryrun -user: test generate systemd uni file

• systemctl --user edit guacamole.service: edit unit file manually

• systemctl --user cat guacamole.service

Troubleshooting

short-name "$container" did not resolve to an alias and no unqualified-search registries are defined in "/etc/containers/registries.conf"

• shortnames it seems arent resolved by default

• Solution: add the following command to /etc/containers/registries.conf

unqualified-search-registries=["docker.io"]
