Bug#801822: same here

[Jakob Schürz]

Hi there!

I wrote a backupscript for btrfs-filesystem and need to activate on
instantiated unit on several timer-units.

Manually
systemctl enable mkbackup at weekly.service mkbackup at daily.service
works.

But  deb-systemd-helper enable $SERVICE >/dev/null || true

But deb-systemd-helper gives me
/usr/bin/deb-systemd-helper: error: unable to read kbackup at daily.service
/usr/bin/deb-systemd-helper: error: unable to read kbackup at weekly.service
for this services.

regards

jakob
