I have a Ubuntu 16.04 server, since the last restart, systemctl doesn't work anymore.
For example if I want to start the nginx, I get the following error:
root@SERVER:/# systemctl start nginx
Failed to start nginx.service: Unknown unit: nginx.service
The same result for every other service. Just systemctl gives the following result:
root@SERVER:/# systemctl
Failed to list units: No such method 'ListUnitsFiltered'
Thanks
service nginx start
or via/system.d
?
