yes restart repeatedly does the same thing and doesn't work

Thanks a ton! This is excellent work!

[systemd-devel] After update from 208->229 can't get calendar timers to work :-\

[warpme]

HI

I updated systemd from 208 to 229 and since then I can’t get working my 
calendar timers.

I spent hours trying to understand why it is not working….

Running „systemctl list-timers” for not working calendar timer shows:

———
NEXT  LEFTLAST 
PASSEDUNITACTIVATES
…..
Wed 2016-03-02 02:25:00 CET   5h 15min left   n/a  
n/a   mythtv-epg-grab-and-load.timer  
mythtv-epg-grab-and-load.service
…..
———

NEXT and LEFT times are shown correctly - so it looks systemd correctly reads 
.timer unit.
All timers are symlinked in /etc/systemd/system/timers.target.wants
But corresponding service is never started.


mythtv-epg-grab-and-load.timer unit is following:
———
[Unit]
Description=Timer for periodic EPG grabing and loading to DB

[Timer]
OnCalendar=Mon,Wed,Fri *-*-* 02:25:00
# OnCalendar=*-*-* 11:05:00
AccuracySec=1us
Unit=mythtv-epg-grab-and-load.service

[Install]
WantedBy=timers.target
———


mythtv-epg-grab-and-load.service
———
[Unit]
Description=@Periodic EPG grabing and loading to DB
After=mysqld.service mythbackend.service

[Service]
User=mythtv
Group=mythtv
Type=oneshot
Nice=19
IOSchedulingClass=2
IOSchedulingPriority=7
ExecStart=/usr/bin/wg++/grab-and-load-epg.sh

[Install]
WantedBy=default.target
———

May somebody hint me where issue is?

I usually do "systemctl restart systemd-networkd" which probably
restarts all devices. This worked for me all the time.

Maybe something like:

$ systemctl restart sys-subsystem-net-devices-enp5s0.device
  ^^
put your device here

Found by "systemctl | fgrep enp"

However, "systemctl show ..." indicates it doesn't support doing that.
