Hi n0nce,
Thanks for the quick reply. I tried just now to update and replace bitcoind.service with apollo.service. Seems to be a similar issue, I got the following message:
Failed to start lightningd.service: Unit apollo.service not found
That's odd; it should exist:
https://github.com/jstefanop/apolloapi/blob/master/scripts/apollo.serviceHowever, try just deleting that line like I said and see if it works that way. Might be fine.
Worst-case, Lightning won't start after a reboot and you'll have to execute
sudo service lightningd restart manually.
