Com a lista completa você tem o nome correto do serviço e pode verificar o estado dele e com isso identificar possíveis problemas.

Confira o estado de um determinado serviço com o exemplo abaixo, altere o serviço para um da sua realidade.

systemctl status console-getty.service

Um bom exemplo de serviço com problema é o dessa matéria, nele ocorre uma falha na instalação do Samba deixando o serviço Masked.

Nesse exemplo basta desmarcar o serviço como Masked para Unmask e o ativar.

systemctl unmask samba-ad-dc.service

Ativar se aplica também aos serviços marcados como Disabled, lembre disso.

systemctl enable samba-ad-dc.service

Caso queira desativar algum serviço confira a matéria abaixo.
