App Indicator Support Required to display tray icon

When I open some apps, like Dropbox, it gives me the error "Unsupported desktop environment." Dropbox requires App Indicator to display the Dropbox tray icon. The Dropbox app has been installed from the software center using the ZORIN OS repository. What do I need to do to correct the problem?

I found no solution. What happens when you click on ignore the popup?
Maybe it only shows that gnome isn't officially supported and needs additionally appindicator. On the website there is reported that dropbox will be changed:

You could try it with the .deb file instead, but I'm not sure if it would make a difference.

Hi, welcome!

It seems to be working fine with Zorin OS Core. I don't have an account to test any further than the login screen after installing it, but I see the icon.

Are you using the Lite version, by any chance? Maybe you need to install an additional package to enable this feature. Launch "Terminal" from the applications menu and run the command:

echo $XDG_CURRENT_DESKTOP

If the output says "zorin:GNOME", then you're using Zorin OS Core. If it says "zorin:XFCE" then you're using the Lite version, in which case you can also run:

sudo apt install xfce4-indicator-plugin

Thank you both. I have uninstalled the software from the software center. When I tried to download Dropbox from the site and run the .deb file, it put me back into the software center. I reinstalled Dropbox from the software center. It appears that I am running Core, so I also installed the xfce4-indicator-plugin, which wasn't present. I will monitor for a couple of days and keep you posted. Thank you for the quick reply and hopefully the solution.

Your profile says you are running Pro. But that means you are running gnome desktop and not xfce, unless you have Pro Lite (xfce desktop).

Welcome to the Forum!

It isn't a ''put back''. It is the Installation Way. When You click on a .deb File, the Installation will apear this Way. Maybe a bit irritating.

To install a .deb File, You have 2 other Options:

  • Install a Tool called Gdebi with the Terminal Command sudo apt install gdebi and use that. This is a little graphical Interface what helps to install .deb Files.
  • You install the downloaded .deb File in the Terminal. to do that, open the Terminal and navigate in the File Directory. Let's say You have it on Your Desktop. Then type cd Desktop and then ls to show all Stuff in the Directory. To install the File type sudo dpkg -i *.deb if You only have one .deb File there. If You have several .deb Files, type sudo dpkg -i File-Name to install the specific File.

Because of the Tray Icons, You could try it with disabling the Zorin AppIndicator Gnome Extension and install the Gnome Extension AppIndicator and KStatusNotifierItem Support - GNOME Shell Extensions and try if that works.
