I used to have a config for openvpn. After upgrading to 18.04 it started behaving differently in relation to systemd, my syslog gets continuously spammed with connection attempts:
ovpn-login[5191]: Options error: In [CMD-LINE]:1: Error opening configuration file: /etc/openvpn/login.confovpn-login[5191]: Use --help for more information.systemd[1]: openvpn@login.service: Main process exited, code=exited, status=1/FAILUREsystemd[1]: openvpn@login.service: Failed with result 'exit-code'.The login.conf does not exist and should not exist - I want to clean this up and get rid of the entry so it stops trying to connect to a service that doesn't exist.
I've tried systemctl kill openvpn@login.service, systemctl disable openvpn@login.service both with systemctl daemon-reload afterwards to no avail.
However, there is no file that matches openvpn@login.service anywhere, it is templated from /lib/systemd/system/openvpn-client@.service.
Presumably I need to keep that file around should I want to add some VPN configs in the future. I did try removing it and doing systemctl daemon-reload as per an answer elsewhere on StackExchange, again, to no avail.
How do I get rid of this spurious systemd configuration entry?
Edit: even after apt purge openvpn and trying to remove all traces it still has:
openvpn@login.service: Failed to schedule restart job: Unit openvpn@login.service not found.
Where is it picking this up from?
