I just discovered that a whole bunch of packages just got deleted from my F27 system after doing an update. This happened on 2 different systems. I discovered this after I had to reboot one of them because the laptop screen went blank. After rebooting it never went to graphics mode. I discovered then that the gdm package had been deleted. I then looked at the dnf.log file and it shows that 12 packages were updated and 119 packages were removed. WTF?
