As the title says, I installed 15.04. One of the first things I did was sudo apt-get install openssh-server.
The next command was sudo restart ssh, which is greeted with an output of:
restart: Unable to connect to Upstart: Failed to connect to socket
/com/ubuntu/upstart: Connection refused
Googling this error tells me that 15.04 switched from Upstart to systemd, but not how to actually restart my ssh daemon using systemd, or whether that's even possible.
I know it's possible to simply switch back to Upstart, systemwide, but will that break other services that have been changed to use systemd after the release?
