No gui in Ubuntu 20.04

[Baa14453]

Hi

Describe the bug
When I run opensnitch-ui the gui does not open, the terminal prints the following error:

E0703 19:32:49.178623442 138958 server_chttp2.cc:40] {"created":"@1593801169.178606296","description":"No address added out of total 1 resolved","file":"src/core/ext/transport/chttp2/server/chttp2_server.cc","file_line":397,"referenced_errors":[{"created":"@1593801169.178603949","description":"Unable to configure socket","fd":26,"file":"src/core/lib/iomgr/tcp_server_utils_posix_common.cc","file_line":217,"referenced_errors":[{"created":"@1593801169.178601233","description":"Address already in use","errno":98,"file":"src/core/lib/iomgr/tcp_server_utils_posix_common.cc","file_line":190,"os_error":"Address already in use","syscall":"bind"}]}]}

Window Manager: GNOME 3.36.2 unfortunately GNOME removed systray icons on >= 3.26.

Do you have the packages gnome-shell-extension-appindicator and libappindicator3-1 installed?

As far as I can tell, it works on the ubunu20.04 live cd with Gnome-Shell as Window Manager.

Oh weird
I do have those packages installed though

Ok, can you install this extension? https://micheleg.github.io/dash-to-dock/ (see if it's available in ubuntu 20 repos, )

The icon will appear on the dock while the GUI is open, so you can hide and show it easily. If you close it, the GUI will exit, i.e., it won't be minimized to the systray/dock. You can also add the icon permanently to the dock.

Another question: when you login the GUI is launched?

I'll try to understand why on the official live-cd the systray icons does appear next to the date.

Ok, please, follow these instructions to install gnome-shell-extension-appindicator from their git:

1. download latest version - https://github.com/ubuntu/gnome-shell-extension-appindicator/archive/v33.zip
2. install it with your regular user: gnome-extensions install gnome-shell-extension-appindicator-v33.zip

Following these steps the icon has appeared.

It's all fine, I understand now
Didn't notice the GUI launched straight into the taskbar, it's opened now and does so on launch I already have the app indicators extension installed.

Thanks for your help 👍
Maybe make it so if you try to launch the GUI twice it restores it from the taskbar to save a future user the confusion, but not a big issue
