Diodon doesn't appear in taskbar after upgrade to Ubuntu 23.04

[Chelmite]

After upgrading Ubuntu from 22.10 to 23.04, diodon no longer appears on the taskbar.
I have tried installing libzeitgeist-2.0-dev (1.0.3-4ubuntu1), zeitgeist (1.0.3-4ubuntu1), but diodon still doesn't appear.

How have you installed Diodon? Per PPA or through the main repository? If through the PPA you will need to add it again after the upgrade, otherwise it won't work.

Use the following commands:

sudo add-apt-repository ppa:diodon-team/stable
sudo apt update
sudo apt upgrade

I've tried the default installation through ubuntu installation, and by using the ppa. The results are the same, nothing on the taskbar.

Finally, I got around to test it on a VM on Ubuntu 23.04. Indeed, sometimes the Diodoon icon does not show app on Ubuntu 23.04, and sometimes after waiting a long time it actually does.

When taking a look into the debug log (when running Diodon as G_MESSAGES_DEBUG=all diodon) the following message occurs:

libayatana-appindicator-WARNING **: Unable to connect to the Notification Watcher

So there seems to be an issue that libayantana which is the library we use for the application indicator, is not connecting to the appindicator extension.

This does not seem to be an issue directly related with Diodon but outside its scope, the Ubuntu AppIndicator and libayantana not playing nicely with one another.

Potentially those are the issues which could cause this:

After a few updates, Diodon is working again!

Awesome that it is working again, and the issue is fixed. Marking as closed. Thanks for the feedback.
