After upgrading to stretch, i removed obsolete packages. However, it apparently included kernel, I was warned about it and misread the question and removed the kernel. However, I found that a newer kernel had been installed. After reboot, there is a blank screen after grub. However, when I select advanced boot options, it boots normally. I tried upgrade-grub but without any difficulties. I compared both entries in the grub (the one in the main menu and the one in the advanced menu and they are the same).
How do I correct the problem?
