OTOH, on my family laptop (also in secureboot mode), when I updated from 8.1.1011 to 8.2.2004, laptop became unresponsive during the microcode_ctl update (in scriptlet) and after that it auto-reset itself , so in the middle of the whole rpm transaction. I tried to recover it but it was to a point where it was faster to just reinstall from scratch with 8.2.2004, which I did ... and in gnome, everything was fine, etc (adding repo, pkgs) but then on the *same* kernel it was installed with, just tried a reboot, and nothing : grub shows menu, you select kernel and on upper left there is only cursor (fixed) and nothing happens .. I'll try to diagnose what's the issue as actually that means troubles with family using that laptop :) -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 17F3B7A1 | twitter: @arrfab
