Hi all, I updated a Dell XPS laptop from CentOS 8.1 (1911) to 8.2 (2004). Installed kernels are kernel-4.18.0-147.5.1.el8_1.x86_64 kernel-4.18.0-147.8.1.el8_1.x86_64 kernel-4.18.0-193.6.3.el8_2.x86_64 Unfortunately I can not boot into the latest kernel-4.18.0-193.6.3.el8_2.x86_64. After grub2 screen I only see following line: EFI stub: UEFI Secure Boot is enabled Booting into the older kernel is still possible. The above line appears and after that the normal kernel output scrolls over the screen (rhgb quiet disabled). Is the new kernel correctly signed? What can I do? -- Thanks Leon
