Having the same issue on Ubuntu 16.10.
Everything seems to be working properly.
I’m able to watch -n1 insynch get_sync_progress.
And watch it progress along nicely.
All my files are in my GUI file explorer.
I just don’t have the widget in the systray.
Same icon with n empty env…
Tried all of the suggestions in this thread.
What did work though was uninstalling, deleting the original folder, and reinstalling. Not sure what happened or what I changed…but now it’s working.
Lol. It’s a great software. Just have to play a little wack a mole with linux glitches.
i managed to solve the issue.
using this modified snippet to get more info:
from PySide.QtGui import QApplication, QIcon, QSystemTrayIcon
import sys, signal
app = QApplication(sys.argv)
QIcon.setThemeName('hicolor')
icon = QIcon.fromTheme('insync-normal')
tray = QSystemTrayIcon(icon)
tray.show()
signal.signal(signal.SIGINT, signal.SIG_DFL)
for path in QIcon.themeSearchPaths():
print "%s/%s" % (path, QIcon.themeName())
sys.exit(app.exec_())
this way i print the paths where the system search for hicolor theme.
In my case it printed:
/home/USERNAME/.icon/hicolor
/home/USERNAME/.icons/hicolor
/usr/share/ubuntu/icons/hicolor
/usr/share/gnome/icons/hicolor
/home/USERNAME/.local/share/flatpak/exports/share/icons/hicolor
/usr/local/share/icons/hicolor
/usr/share/icons/hicolor
/var/lib/snapd/desktop/icons/hicolor
and takes the first folder that exists.
In my case these were all empty but /home/USERNAME/.local/share/flatpak/exports/share/icons/hicolor, since time ago i installed an app using flatpack. Purging flatpack from the system solved the issue (since obviously there were no insync icons there).
Hi,
I experienced the same issue with my ubuntu 16.04 machine when I installed flatpack, I purgue it and my insync icons went back, but I need to have flatpack installed, there is a way to have both apps installed without loosing any of its funcionalities.
JC.
In version 1.3.15 the icon came back!!! Thank you
Yes, Now show icon perfectly!! Thanks! 
I installed insync on mint 18 and have no tray icon.
I ve reinstalled with no luck.
Its running without tray icon.
when I type the above command I get the following:
“sni-qt/2328” WARN 22:45:34.747 void StatusNotifierItemFactory::connectToSnw() Invalid interface to SNW_SERVICE
No systemtrayicon available
ERROR:root:Cannot initialize notifications.
Try:
sudo cp /usr/share/icons/hicolor/48x48/status/insync* /usr/share/icons/Adwaita/48x48/status/
sudo gtk-update-icon-cache /usr/share/icons/Adwaita
sudo cp /usr/share/icons/hicolor/48x48/status/insync* /usr/share/icons/gnome/48x48/status/
sudo gtk-update-icon-cache /usr/share/icons/gnome
Then restart GNOME (Alt-F2 r).
