Unable to reproduce the issue on ubuntu 17.10 using chrome reported version #71.0.3573.0 Channel: dev. Observed that there is a status icon for chrome in the system tray as expected.
Attached a screen shot for reference.
The issue seems to have been reported on Ubuntu 16.04.5. Hence, forwarding it to inhouse team for further triaging of the issue.

Thanks...!!

That is not the icon I meant. I mean the system tray "appindicator" icon which is missing in your screenshot.

I know the switch from Unity to Gnome changed where icons appear and that made me wonder if maybe it was just hidden or moved. I remembered I have a VM with 18.04 and an older version of chrome (68.0.3440.106) installed in it, so I started that up to compare. It looked the same as the screenshot at first, but after some debugging, it turns out the tray icon requires an extension that runs in the background to be enabled (in addition to the background apps setting). I installed the hangouts extension (https://chrome.google.com/webstore/detail/google-hangouts/nckgahadagoaajjgafhacjanaoiihapd) and the tray icon appeared.

I updated to the latest stable (69.0.3497.100) and the icon was still working correctly. I then installed the latest dev version (71.0.3573.0), the same as on my 16.04 install and verified that the icon was indeed missing.

So in summary, the icon is missing for both 16.04 and 18.04 and stopped working somewhere in the 69-71 range.

I attached a screenshot of my 18.04 VM with the icon correctly appearing.

Observation:
-----------
Hangouts icon & chrome icon is not shown in status tray as screenshot shown in C#3.

Thanks..!

I was talking about Gnome in reference to 17.10 and later (including 18.04) since unity was replaced with Gnome by default after that point. In 16.04 I am using Unity (the default). Furthermore, that screenshot in comment #3 was with 18.04, not 16.04. I can do more testing later if needed, but this issue should be reproducible with the default UI in 16.04 or later (Unity in 16.04, Gnome in 17.10+). It may be reproducible before 16.04 too but I haven't tested that to see.

As to installing Gnome in 16.04, I believe that may not show status icons by default. In 17.10+ Ubuntu, by default, uses a Gnome extension to show appindicator icons. I do not know if that exists for 16.04, or if it is installed by default along with Gnome. 

Thank you for providing more feedback. Adding the requester to the cc list.

[GTK] Fix libappindicator library name for dlopen()

STRINGIZE(GTK_MAJOR_VERSION) evaluates to "(3)", so we previously tried to open
"libappindicator(3).so.1" when we wanted to open "libappindicator3.so.1".
