I agree it is a lot of shorthand because of expectations. In the endwe (the
list) don't know what you have on your system or what state itis in. In order
to get that information to help we would need you totry the following:
1. boot using a working USB/cdrom/netboot path and installer2. choose the
rescue mode3. have the rescue mount the disks as local and chroot into
thesystem. << if possible have the system also bring up networking >>
Thenyum list kernel shim grub2 mokutil
John,
I have a CentOS 8.2.2004 system running on an EPYC-equipped SuperMicro
motherboard. I assume it uses EFI boot. I have it set to auto-update with
cron.daily, so it almost certainly has the buggy package(s) installed. I'm
loath to try rebooting it just to see.
When I run "yum list kernel shim grub2 mokutil" all I get back are the three
installed kernel packages. Reverting to the old fashioned "rpm -qa | grep
kernel-4 ; rpm -qa | grep shim ; rpm -qa | grep grub2 ; rpm -qa | grep mokutil"
I get:
kernel-4.18.0-147.8.1.el8_1.x86_64
kernel-4.18.0-193.14.2.el8_2.x86_64
kernel-4.18.0-193.6.3.el8_2.x86_64
grub2-tools-2.02-87.el8_2.x86_64
grub2-pc-2.02-87.el8_2.x86_64
grub2-pc-modules-2.02-87.el8_2.noarch
grub2-common-2.02-87.el8_2.noarch
grub2-tools-efi-2.02-87.el8_2.x86_64
grub2-tools-minimal-2.02-87.el8_2.x86_64
grub2-tools-extra-2.02-87.el8_2.x86_64
I apparently do not have either shim or mokutil packages installed. I'm not
sure what this means. Am I not using EFI boot?
I have local copies of the earlier v2.02-81 grub2 packages. Would it be
worthwhile to replace my v2.02-87 grub2 packages, then add this line to
/etc/dnf/dnf.conf:
exclude=grub shim mokutil
as previously advised?
Or should I just leave well enough alone and wait for tonight's auto-update to
fix things?
