** Description changed:
- On a RISC-V Ubuntu 24.04 I installed ubuntu-desktop.
+ Impact
+ ------
+ GNOME Remote Desktop won't work for systems that were upgraded from earlier
Ubuntu releases.
- The desktop does not show up though gdm3 is running.
+ Test Case
+ ---------
+ Install Ubuntu Desktop 23.10
+ Upgrade to 24.04 LTS
+ Successfully complete both the Basic RDP and Basic Remote Login test cases
from https://wiki.ubuntu.com/DesktopTeam/TestPlans/RemoteDesktop
- I see the following error messages which might indicate a dependency
- issue:
+ What Could Go Wrong
+ -------------------
+ The small debian/rules change ensures that systemd-sysusers is run and that
it is run after systemd-tmpfiles.

+ This is the minimal change needed to fix this bug.
+
+ GNOME Remote Desktop only works with GNOME Shell so this change only

+ critical feature for some users who may not have local access to the
+ system they are trying to use. However, this feature is a bit less
+ useful before Ubuntu 24.04 LTS which is the first version to support
+ headless remote desktop using RDP.

that this upgrade would run:

+ tmpfiles.conf
+
+ sudo systemd-sysusers /usr/lib/sysusers.d/gnome-remote-desktop-
