I've upgraded to 13.10 and now I don't have the standard menu clock, which I need for work.

I checked and 'indicator-datetime' is installed. I even uninstalled/reinstalled that applet with no luck.

Also my "clock" settings under System Preferences are all disabled. I can't change anything.

Does anyone know how I can get the old menu clock back?

Alternatively is there another menu clock app I can download?

Edit 1

Thanks for the responses

  1. I've restarted several times and that didn't fix the issue.

  2. I just ran the 13.10 update today. But I ran it again a few minutes ago. I got about 200KB in random updates. The issue is still present after a reboot.

  3. # apt-cache policy indicator-datetime indicator-datetime: Installed: 13.10.0+13.10.20131016.2-0ubuntu1 Candidate: 13.10.0+13.10.20131016.2-0ubuntu1 Version table: *** 13.10.0+13.10.20131016.2-0ubuntu1 0 500 http://us.archive.ubuntu.com/ubuntu/ saucy/main amd64 Packages 100 /var/lib/dpkg/status

Edit 2

I believe the issue is related to 'rarings' changing the systray somehow... http://www.omgubuntu.co.uk/2013/02/raring-retires-system-tray-whitelist

Or systray disappeared, although I haven't got that solution to work yet.

Edit 3

Because of a suggestion from RolandiXor I've check the binaries. My system is missing 'libical.so.0' but it has 'libical.so.1'.

ldd /usr/lib/x86_64-linux-gnu/indicator-datetime-service
libical.so.0 => not found

Does anyone know how to get the libical.so.0 binary that the datetime service needs but doesn't install?

    Are you sure you are up to date? Check the updater please. This bug should have been fixed already.

  • Can you add the output of apt-cache policy indicator-datetime?

  • I have this same issue. I've found that doing a purge of indicator-datetime, reinstalling, and logging out will bring back the clock and all settings. However after one or two reboots the problem returns.

    Have you run indicator-datetime manually? (You can find its location on your system by running locate indicator-datetime).

    Just had the same issue with Ubuntu 14.04 LTS. Had to use killall unity-panel-service Jun 12, 2014 at 10:56

There's a bug report for that in Launchpad.

Quick fix:
Open terminal (ctrl + alt + T) and type

killall unity-panel-service

    Thanks, but I've restarted the computer many times. It's not a process restart issue.

    Or you can just press "Alt+F2" and type the same and it will work.

    Marking as answer as it's probably what most readers will need. But for me it was a library loading path problem due to the fact that the datetime service seems to load from /usr/local before /usr for some reason.

    Use 'restart unity-panel-service', there is no need for reboot.

I had the same problem. I performed a reboot and my clock is back.

  • killall unity-panel-service this worked like a charm for me ,no need for repoot :D Apr 14, 2015 at 8:44

Found the issue. I built a few libraries from source earlier in /usr/local/lib . indicator-datetime-service found those libraries before the system libraries in /usr/lib for some reason. It shouldn't have done that.

One of those libraries pulled in the old libical.so.0 dependency which was no longer available. When I deleted all the GNOME/Evolution related libraries in /usr/local/lib I could start indicator-datetime-service again and my clock shown up.

So also try...

ldd --verbose /usr/lib/x86_64-linux-gnu/indicator-datetime-service

And look for any "not found" messages in the output. If you have a library dependency issue it will most likely show up in that output.

  • while that might have solved your specific issue, i tried that procedure and got no "not found"'s. is that because i ran that AFTER "fixing" the issue with the accepted answer?

  • @kervin: Running this check on my Desktop 14.0.2 LTS (x86_64 with kernel v 3.16.0-41-generic) had the same results as that reported in the above comment. And I have not fixed anything yet, contrary to him. Would you care to elaborate on how to proceed on the "missing library" or PATH front ? I am stuck. Tx.

  • @kervin: File was no found because (perhaps in newer versions of the kernel) the path for that file is: /usr/lib/x86_64-linux-gnu/indicator-datetime/indicator-datetime-service ......... I don't know what is going on here. Any hint or help so I can further try to solve this hih¡ghly appreciated.. I am stuck. Tx.

I had the same problem, (no clock displayed and settings disabled) I had to select the default server for update in System Preferences. Reboot, and the clock was back.

  • It was likely just the reboot that fixed your issue.
