Description Michal Schorm 2024-05-18 17:40:37 UTC
Installing Cinnamon GUI over a headless server running on bare metal,
with "dnf groupinstall cinnamon"

After system reboot, system hangs with:
[FAILED] Failed to start lightdm.service - Light Display manager
[FAILED] Failed to start lightdm.service - Light Display manager
[FAILED] Failed to start lightdm.service - Light Display manager
[FAILED] Failed to start lightdm.service - Light Display manager
[FAILED] Failed to start lightdm.service - Light Display manager
[FAILED] Failed to start lightdm.service - Light Display manager

No recovery possible, all boot entries, rescue included, ends up the same.
No prompt available, system lost.

========

lightdm installation scriptlet logs:

Running scriptlet: lightdm-1.32.0-9.fc40.x86_64                       820/952

dbus-daemon: no process found
Created symlink /etc/systemd/system/display-manager.service → /usr/lib/systemd/system/lightdm.service.

After running
dnf reinstall lightdm after the first dnf transaction, the scriptlets do not log any problems, but lightdm still does not work.

Setting severity to "urgent". I don't need to fix it urgently, but more fitting severity "critical" is not available in the list.

You need to install Xorg

sudo dnf install xorg-x11-server-Xorg
