#1660 TC on kubuntu 18.04 not starting / does not show any window

[Andreas Helmcke]

On kubuntu 18.04 64 Bit taskcoach does not work.
It will start but does not show any window.

Errormessages on console when starting taskcoach in terminal:

+1 (I also face this bug on Ubuntu 18.04) (#1661 seems to be a duplicate of this issue.)

[Torsten Kelsch]

I also experience this bug, but on Xubuntu 18.04., with the same messages that the thread starter posted.

[Andreas Helmcke]

Patch https://sourceforge.net/p/taskcoach/bugs/1593/ works for me.

Thanks to Max Mopp who mentioned it in his comment on Bug [#1661]

[Torsten Kelsch]

I followed the instructions on https://wiki.ubuntuusers.de/patch/, but I must have done something wrong, as it does not work for me:

try:
sudo patch -p0 -i /PATH-TO-PATCHFILE/taskcoach_gtk3_v3.patch -d /usr/lib/python2.7/dist-packages

[Torsten Kelsch]

Thanks, Andreas, that did the trick! Wonderful to have a working Task Coach again!

[Torsten Kelsch]

While finishing the program, the following error message appears:

/usr/lib/python2.7/dist-packages/taskcoachlib/notify/notifier_libnotify.py:31: PyGIWarning: Notify was imported without specifying a version first. Use gi.require_version('Notify', '0.7') before import to ensure that the right version gets loaded.
import gi.repository.Notify

What is that notifier, and is it possible to disable it, and if it is, how can I do it? Anyway, I haven’t seen this message in all the years I’ve been using Task Coach, so I think it must have something to do with the patch. Any ideas? Thanks in advance.

[Christian Perreault]

Hi! Thanks Andreas, that did the trick for me too!
Concerning the previous mentionned warning, that turns into an error alert when closing the application, I created a patch that fixed it on my side. I attach it to this comment and the command to apply it is:

sudo patch -p0 -i /PATH-TO-PATCHFILE/warning_gi_libnotify.patch -d /usr/lib/python2.7/dist-packages

[Torsten Kelsch]

Thanks, Christian, it works!

[Paul McKimmy]

+1, applied both patchfiles and appreciate your assistance!!

[Sjef]

Had to patch my TaskCoach too. Just a question: will there be a new version shortly, one that doesn't require these patches?

[Wolfgang Helm]

I would like to know that, too, because neither the patch nor de- and reinstalling helped me.

[Wolfgang Helm]

...oh, it works again - don't know why. Maybe some automatic update...

[Aaron Wolf]

We just released 1.4.4 please help us verify that it works now without any extra patching. Cheers

[Sjef]

Upgraded. No patch required here (yet ;-). Thanks!!

[Torsten Kelsch]

Seems to work fine on Xubuntu 18.10 (64 bit).
