[Bug]: In Gnome with AppIndicators extension, status icon is missing (showing "...")

[RalfJung]

Using the Gnome debug facilities, I can determine that the IconName property of this AppIndicator icon is set to state-ok. This icon seems to exist for KDE's "breeze" theme, but not in the global "hicolor" folder or the Gnome theme:

$ find /usr/share/icons -name "*state-ok*"
/usr/share/icons/breeze-dark/status/22/state-ok.svg
/usr/share/icons/breeze-dark/status/16/state-ok.svg
/usr/share/icons/breeze/status/22/state-ok.svg
/usr/share/icons/breeze/status/16/state-ok.svg

So it seems like the Nextcloud AppIndicator assumes icons to exist that do not generally exist? I am not really sure how this is supposed to work though.

Could you share how you found that information/debugged Nextcloud for that case? I could not find any error message or anything and I do not have an Icon at all.

I used the instructions I found here, except that instead of r(0)._indicator._proxy.Id I checked r(0)._indicator._proxy.IconName.

Maybe for you other information is helpful that other people shared on the net. If you have ... as the icon, the gtk icon library might be missing. It is probably bundled in libappindicator-gtk3 on Fedora, and something similar on others distros :)

I don't see any package like that on Debian...

In my case what helped is to go into the settings of gnome-shell-extension-appindicator, and set a custom icon for "Indicator ID": Nextcloud, "Icon Name": Nextcloud. Now I have the nextcloud icon. It doesn't reflect the current sync status; that seems to be the part that's breaking the icon in the first place, judging from this "state-ok" icon name.

@RalfJung Maybe try Try libappindicator3. 🤔

I found my problem though...extensions were completely disabled somehow. Dunno how that happened.

libappindicator3

That package is installed. 🤷

Also, other indicators have icons that work fine. So I don't think it's a system/setup issue. It's only Nextcloud that does not work (from the few applications I tried).
