** Description changed: - Steps to reproduce: + Impact + ====== + A minimal QEMU image of Ubuntu Desktop will fail to start after installing. This is because of a gnome-remote-desktop crash made worse because the gnome-remote-desktop service was always running. This update fixes the crash and stops gnome-remote-desktop from running when it's not in use. + + We worked around this bug before the Ubuntu 22.04 LTS release by + updating osinfo-db so that installs using GNOME Boxes and Virt Manager + would do the right thing by default. But that didn't help for this + particular test case. + + Test Case + ========= 1. On a jammy host, create a jammy guest: $ qemu-img create -f qcow2 vm.qcow2 50G $ qemu-system-x86_64 -accel kvm -cpu host -smp cpus=4 -m 3072 -device virtio-vga -display gtk,grab-on-hover=on -hda vm.qcow2 -cdrom [jammy ISO] 2. Install Ubuntu in that VM (minimal install), no problems are expected yet. 3. After the installation is concluded and the VM reboots, try to login using the Wayland session (it should be the default, no need to select anything). It will fail and bring you back to the login screen (apparently due to a gnome-shell crash; I don't think the details are relevant to the problem here). What is expected: that both the Wayland and X11 sessions work out-of- the-box. - Workaround: remove gnome-remote-desktop, and the Wayland session will - work just fine in the conditions described above. This is why I'm - reporting this issue in gnome-remote-desktop instead of Wayland or - gnome-shell or qemu. I might be wrong though... + Workaround + =========== + remove gnome-remote-desktop, and the Wayland session will work just fine in the conditions described above.
