DesktopService exceptions hinder subsequent service initializations

[Erich Eickmeyer]

Looks like geolocation is failing, probably due to lack of GNOME Shell location services.

flutter: ERROR ubuntustudio-system-installer: Unhandled exception
        StateError: Bad state: GetIt: Object/factory with type GeoService is not registered inside GetIt.
(Did you accidentally do GetIt sl=GetIt.instance(); instead of GetIt sl=GetIt.instance;
Did you forget to register it?)

Coudl you add your /var/log/installer/ubuntu_desktop_installer.log to the report? (or the equivalent if the name is different by flavor)

[Sebastien Bacher (seb128)]

The journal log might also be of use there if you could also add it?

I had a quick look at this and suspect that the error message is misleading. It seems like it's possible that a service registration/initialization, which runs before the geo service registration/initialization, fails - causing the geo service to never get registered at all.
The most likely point of failure is the default GNOME-based implementation of the desktop service, which takes care of inhibiting the screensaver, auto-mounting media, etc. Journal logs would definitely help confirm this suspicion.

In any case it's something we should fix in ubuntu-desktop-provision.

[Erich Eickmeyer (eeickmeyer)]

Here's the equivalent of ubuntu-desktop-installer.log, or as we call it using the ubuntu-flavor-installer stuff, ubuntustudio-system-installer as we already had nomenclature for that in some documentation.

And here's the journal output.

[Dennis Loose (dloose)]

Thanks, that confirms it!

This prevents the subsequent service initializations (including the geo service) from running, causing a crash later on.

Will try to fix it later this week or next week.
