GLib-GIO:Settings schema 'org.gnome.Geary' does not contain a key named 'single-key-shortcuts'

[hkdb]

If users have been using Geary (installed from .deb) in previous Ubuntu releases, after upgrading to 20.04 LTS, Geary doesn't launch.

Attempting to launch it from terminal, the below message shows:

GLib-GIO:Settings schema 'org.gnome.Geary' does not contain a key named 'single-key-shortcuts'
Trace/breakpoint trap (core dumped)

This is due to the new /usr/share/glib-2.0/schemas/org.gnome.Geary.gschema.xml not being compiled and placed into /usr/local/share/glib-2.0/schemas/. The new changes were introduced in Geary 3.35.2. In order for the new changes to apply and be made available for Geary, a working post-install hook must be included with the .deb. Upstream uses this post-install hook for Flatpak:

https://gitlab.gnome.org/GNOME/geary/-/blob/mainline/build-aux/post_install.py

Perhaps we can use the above and add an extra step of moving the compiled file to /usr/local/share/glib-2.0/schemas/ is needed for our situation as the compiled output goes to /usr/share/glib-2.0/schemas/ but Geary reads from /usr/local/share/glib-2.0/schemas/?

I have done a quick write-up about how to manually fix the problem as an interim solution:

For my specific situation, this happened after upgrading to 20.04 [amd64] with this package from 19.10 [amd64] running Geary 3.34.2-eoan-1 from https://launchpad.net/~hkdb/+archive/ubuntu/geary.

1. Description: Ubuntu 20.04 LTS

3. Geary would launch normally
4. Geary crashes on launch

Thanks!

Thank you for your bug report. The /usr/local isn't used by Ubuntu, if there is content here it's a local installation and such the responsability of the local administrator who decided to override the Ubuntu version. Try cleaning or moving away /usr/local and see if it resolves your issue
