murtezayesil I recently upgraded all the packages. Linux-current was one of the packages but it turns out linux-current-headers isn't a dependency. System can boot but no display. I had to restart and choose LTS from GRUB to install linux-current-headers. Version no: 5.0.7 release 114
Harvey linux-headers-current isn't marked as a dependency of linux-current because, its not a dependency. No idea why this resolved an issue for you. None of my 3 PC's have it installed, nor do the 3 vm's I have for testing.
Justin Headers are only required if you're compiling something... What does your eopkg history show? Were other packages pulled in that the same time? Did you upgrade while in the LTS kernel also?
