• What is the current behavior?

We currently use systray to interact with tray bar. On linux this requires libappindicator3 to work (v1.1.0). This library is old and deprecated. See debian release notes:

The deprecated libappindicator libraries are no longer provided. As a result, the related packages libappindicator1, libappindicator3-1 and libappindicator-dev are no longer available. This is expected to cause dependency errors for third-party software that still depends on libappindicator to provide system tray and indicator support. Debian is using libayatana-appindicator as the successor of libappindicator. For technical background see this announcement.

• What is the new behavior?

The new library is libayatana-appindicator which is supported by systray starting from version 1.2.0. But there seems to be problems with that version of the lib. See https://github.com/getlantern/systray/issues/191#issuecomment-1118329060. Using the fork https://github.com/fyne-io/systray seems to be a better alternative for various reasons:

1. there are no lib dependencies to install and to link against during the go build
2. the new lib allows starting the binary even if there is no GUI. The binary prints this message but starts nonetheless: systray error: failed to register our icon with the notifier watcher (maybe no tray is running?): The name org.kde.StatusNotifierWatcher was not provided by any .service files. So we do not need the arduino_create_agent-cli version anymore.
3. the first point allows us to build statically the agent, allowing it to run on almost everything:
