Expected behaviour

Desktop Tray icon should be present

Actual behaviour

On Ubuntu 20.10 (Groovy Gorilla) the tray icon appears to not show at all, the nextcloud background process is however running OK and syncs appear to be running OK - Not sure if its an 20.04 > 20.10 upgrade issue or if its present on 20.10 out of box

Steps to reproduce

1. Ubuntu 20.10 installed (i upgraded from 20.04)
2. Run Nextcloud, close app window
3. note no tray icon

What is odd to observe is the window now loads off the dock rather than the top bar like before

Wouldn't that be #1977 getting worse?

[anthonysomerset]

Its possible - but i never experienced the issue reported there that i remember - I should add that there is no icon at all - not even an empty space or incorrect icon

[er-vin]

OK. That said (and unfortunately) I might need you to do similar investigations than the people on that other ticket. This kind of issues tend to be somewhere outside of our code and so it's hard to locate outside of a machine which is not affected.

Word of caution: even if we do find the culprit we might or might not be able to do something about it, we're merely delegating that stuff to QSystemTrayIcon...

[anthonysomerset]

Sure - more than happy to debug as requested - just let me know what you need me me to gather

[er-vin]

Let's summon @veddox who did a good chunk of that investigation on the other ticket, he might have good ideas to get you started.

I had a similar issue. On Ubuntu 20.04 I had absolutely no problem. I have upgraded on Saturday to Ubuntu 20.10. The tray was not appearing. I have uninstalled the client from the Software Manager. Then I've tried to re-install it but now I have a missing dependency:

sudo apt install nextcloud-desktop

The following information may help to resolve the situation:

The following packages have unmet dependencies:

I've tried to download and use the AppImage from Nextcloud website but it slows my laptop like never before…

[anthonysomerset]

i just tried this also - the reinstall was OK - i note you are referencing focal packages not groovy so perhaps PPA not updated for you

looks like the icon is working again after reinstall - will perform some more tests and advise

[er-vin]

Looks like it's tied to the packaging somehow then... @ivaradi any idea?

[janvlug]

I have similar problems (also as #1977) on Fedora 33 I just upgraded to from Fedora 32. I'm using GNOME (3.38.1) on Wayland.
However, if I start a GNOME desktop session on Xorg, the icon is visible.

[q-wertz]

I have the same problem.
When you do cat /var/log/syslog | grep nextcloud what is the result?
I get:

Clearly a crash, seems to be somewhere in QtSingleApplication but the backtrace is trimmed. You got a core dump though, so you might be able to open this with gdb and produce a more complete backtrace (bonus point for installing debug symbols and debug sources first which would give something more likely to be exploitable).

[janvlug]

I zipped the ABRT crash directory, although ABRT stated it was of low informational usage:
crash.zip

I have similar problems (also as #1977) on Fedora 33 I just upgraded to from Fedora 32. I'm using GNOME (3.38.1) on Wayland.
However, if I start a GNOME desktop session on Xorg, the icon is visible.

This is interesting as I have exactly opposite situations.
Upgraded from Ubuntu 20.04 to 20.10 and I'm using GNOME (3.38.1) on Xorg with no visible icon.
However, if I start a GNOME desktop session on Wayland, the icon is visible.

Update: It's gone on Wayland now same as Xorg!, Seems to be an intermittent issue.

[omid-1985]

Ok, here is a temporary fix:

1. Run these two commands below to make an executable script:
   $ (echo '#!/bin/bash' && echo 'sleep 5' && echo '/usr/bin/nextcloud') > nextcloud-delayed-startup
   $ chmod +x nextcloud-delayed-startup

Or if you are using AppImage, replace /usr/bin/nextcloudwith your Nextcloud AppImage path

2. Deselect Nextcloud Lunch on System Startup:

Or if you can't run it because it's already running but hidden in the background, close it with killall nextcloud, run it manually and deselect the option above.

3. And add your own created script into startup:

[anthonysomerset]

so my issue came back again - lock/logout did not fix - had to open the gui, exit fully then re-open - i seem to have a similar issue with synergy as well

[christianhubmann]

I've made the following observation:
When I log into Gnome on Ubuntu 20.10, no icon is shown even though Nextcloud is running. If I then kill the process and start Nextcloud again, now the icon is shown.
Could this be a timing issue? This would explain why the temp. fix from @omid-1985 is working.
It happens to me on both Wayland and Xorg.

[repsorp]

When I log into Gnome on Ubuntu 20.10, no icon is shown even though Nextcloud is running. If I then kill the process and start Nextcloud again, now the icon is shown.

Same here but once the Nextcloud client has been relaunched this way it is then impossible for me to connect to my Nextcloud account through Gnome Online Accounts (more details here)

[er-vin]

This clearly looks like a timing issue... honestly I'm tempted to blame the systray code of Gnome. We're just requesting a systray icon, even if we got started before the gnome systray code kicks in (we got no control over that) that systray should find the nextcloud client is around and display the icon. KDE Plasma isn't affected by this for instance, even if the nextcloud client is faster to start than the rest of the session the icon is displayed just fine.

I can confirm this observation. Totally works when the client is started "late enough", whatever that means precisely.

[fnkr]

Here is my workaround, based on @omid-1985's comment but simpler:

Just update the Exec option in ~/.config/autostart/Nextcloud.desktop:

Exec=/usr/bin/bash -c 'sleep 5 && exec /usr/bin/nextcloud'

To revert the change (after the issue is fixed), just uncheck and check the Launch on System Startup checkbox in Nextcloud settings.

[repsorp]

Here is my workaround, based on @omid-1985's comment but simpler:

Doesn't work here, still no systray

Regular error message:

@repsorp Did you try it with a sleep 15 instead of sleep 5? Helped in my case.

@repsorp Did you try it with a sleep 15 instead of sleep 5? Helped in my case.

I just tried it but it didn't work either
Systray shows up (sometimes it doesn't...) if I restart nextcloud-gui

[gbwebdev]

I've made the following observation:

• If I check "Launch on System Startup" in the settings then, when I login :
  • No icon in the systray
  • The "settings" window is opened
• If I do not check "Launch on System Startup" then :
  • Obviously nothing appears when I login (no icon in the systray, no window opened)
  • If I manually start the Nextcloud-client app then the icon appears in the systray and no window is opened (which is the desired behavior, except that I have to manually start the app).

@fnkr's workaround works for me.

[fnkr]

There seems to be a bug in the AppIndicator GNOME Shell Extension that's causing this: ubuntu/gnome-shell-extension-appindicator#250 (maybe 👍 there too) - I had the same problem with Flameshot, so it's not just Nextcloud. Also tray icons work for me when I'm using i3 instead of GNOME.

[er-vin]

At that point, this is clearly a desktop environment issue. We can't do anything about it. I'll thus close it.

[jim-perkins]

Here is my workaround, based on @omid-1985's comment but simpler:

Just update the Exec option in ~/.config/autostart/Nextcloud.desktop:

Exec=/usr/bin/bash -c 'sleep 5 && exec /usr/bin/nextcloud'

This worked for me on a fresh Ubuntu 20.04 installation. thanks so much. Whats weird is I have a Ubuntu 20.04 installation at home that does not exhibit this upstream? bug. One possibly related difference is that the issue exposes itself on a laptop using wifi and not on a desktop computer connecting via ethernet.

[mbogner]

Was this reported at gnome?

Adding the sleep also helped to bring back my tray icon.

[cnmicha]

Yes, it has already been reported. But there doesn't seem to be much activity.
ubuntu/gnome-shell-extension-appindicator#250

[ferdiga]

#2597 (comment)
works for me

[dregad]

Facing the same issue, but on Ubuntu 20.04.1 LTS - no systray icon whatsoever but sync is working.

Stopping and restarting the nextcloud client fixes the problem for me, i.e. the tray icon appears

$ killall nexcloud
$ nextcloud &

I'll test the trick with delaying startup (#2597 (comment)) later, as I can't end my session right now.

[dregad]

Wondering if ubuntu/gnome-shell-extension-appindicator#260 might fix this issue...

[mbogner]

Ah. I am also using ubuntu LTS as mentioned above. The workaround with the sleep fixed it for now.

[johanehnberg]

Here is my workaround, based on @omid-1985's comment but simpler:

Exec=/usr/bin/bash -c 'sleep 5 && exec /usr/bin/nextcloud'

One-liner for automation:
sed -i "s#/usr/bin/nextcloud#/usr/bin/bash -c 'sleep 5 \&\& exec /usr/bin/nextcloud'#" ~/.config/autostart/Nextcloud.desktop

[fvonberg]

I am using the AppImage from Nextcloud with Ubuntu 20.04.
For me it worked to append:

X-GNOME-Autostart-Delay=10
X-MATE-Autostart-Delay=10
X-KDE-autostart-after=panel

to my com.nextcloud.desktopclient.nextcloud.desktop.

Found that Solution in the *.desktop from the jetbrains toolbox.

[Stern1710]

I am using the AppImage from Nextcloud with Ubuntu 20.04.
For me it worked to append:

X-GNOME-Autostart-Delay=10
X-MATE-Autostart-Delay=10
X-KDE-autostart-after=panel

For any Gnome-based environment, such as Ubuntu or Pop! OS which I am using, adding X-GNOME-Autostart-Delay=10 is enough. KDE and MATE are for the other respective environments. I also tuned down the delay time to about 2 seconds which seems to be enough so far for my Thinkpad, if any problems occur in the future, I will give an update

to my com.nextcloud.desktopclient.nextcloud.desktop.

Thanks for point this one out @fvonberg, helped me find the file. The appimage version seems to be using com.nextcloud.desktopclient.nextcloud.desktop, whereas other versions are storing the entry in Nextcloud.desktop

[er-vin]

Note that the "X-KDE-autostart-after=panel" is likely useless though. By default it gets a "X-KDE-autostart-phase" of 2 which is after any "platformy" thing is started anyway.

[soleuu]

ubuntu 20.04 (using nextcloud-desktop package)

• MATE : no need to add delay. It's working fine.
• Gnome Shell : using "X-GNOME-Autostart-Delay=10" resolved the problem.

[Stern1710]

I tried it with `Delay=2' and it works fine, maybe somebody just wants less delay until the client starts. Just try it out for yourself if that works as well.

2 seconds sleep did it, tks

[pmorch]

I realize that the OP had a different problem, but I was also experiencing "Desktop Client - SysTray Icon does not show" (but on NixOS - not really relevant).

My problem was that I didn't have the AppIndicator and KStatusNotifierItem Support extension installed.
