I can't see any icons ( telegram/hangouts/viber and etc.) in the panel of Ubuntu 16.04. They do show up in the launcher though:
How should I proceed?
I don't have any of this installed:
indicator-application indicator-appmenu indicator-bluetooth indicator-common indicator-datetime indicator-keyboard indicator-messages indicator-network indicator-power indicator-printers indicator-session indicator-sound indicator-transfer indicator-transfer-download-manager
So Indicator icons do not appear after upgrade to Ubuntu 17.10 don't solve my problem. Any suggestions please?
I just change some files in .local/share/applications because the icon of hangouts don't show up in the panel. And after that all icons don't show in the panel. How can i reset to the defaults files in .local/share/applications ? Please help.
