Systemd Timer Template after boot?

Question

I have a templated timer that calls a templated unit. I use the following to enable and start them:

sudo systemctl enable ping@.timer
sudo systemctl enable ping@service
sudo systemctl start ping@hello.timer

This works as expected, and the timer activates ping@hello.service as expected. However this doesn't persist after reboots, presumably because I didn't enable the instance of the timer. But the following fails with a "does not exist" error:

sudo systemctl enable ping@hello.timer

How can I have a templated timer start at each boot?

What is the actual error you received? What version of systemd? — Michael Hampton, Jul 04 '20 at 18:43

Error was with me - the "trick" is to use two enables on the timer:

sudo systemctl enable ping@.timer
sudo systemctl enable ping@service
sudo systemctl enable ping@hello.timer

I was getting an error as I was trying to enable the instance of the timer before the template.
