strace -f timedatectl

Comment 2 Juan Orti 2016-06-06 19:40:37 UTC
Looks like a there is a clashing BusName=org.freedesktop.timedate1 in /usr/lib/systemd/system/timedatex.service and /usr/lib/systemd/system/systemd-timedated.service

How do I fix this?

(In reply to Juan Orti from comment #2)
> How do I fix this?

# systemctl mask systemd-timedated
# systemctl stop systemd-timedated

In https://bugzilla.redhat.com/show_bug.cgi?id=1187072, timedatex.service was enabled in by default. timedatex.service should include Conflicts=systemd-timedated.

Comment 4 Juan Orti 2016-06-14 07:42:23 UTC
Ok, masking that unit fixes the problem. Thank you.

Comment 5 Miroslav Lichvar 2016-06-14 07:51:43 UTC
The timedatex package includes a symlink which masks systemd-timedated by default. Was the symlink removed? Maybe something related to presets?

Comment 6 Juan Orti 2016-06-14 08:06:00 UTC
This problem happened after I did a failed dnf upgrade to f24 which ended with many duplicate packages from f23 and f24. As I did a btrfs rollback of the root filesystem I thought everything was ok, but maybe I messed up things playing with the dnf command.

Comment 7 Jan Synacek 2016-06-14 10:13:48 UTC
I've just verified that after installing F23, fully updating it and updating to F24 still leaves systemd-timedated masked.
