No new Kernels in /boot Directory after Minor updates in Fedora33

No Kernels in /boot Directory after Minor updates in Fedora33

Hi,

since updating my Fedora System from 32 to 33 I can’t update the kernel anymore. However, the system claims to have three Kernel installed. Kernel 5.8.16 stays , even though there are newer kernels in place. After updating the system to 5.9.12 the Kernel 5.9.10 got removed, but the Kernel 5.8.16 remains curiously.

Installed Kernel Cores
[root@tux1980 entries]# rpm -qa | grep kernel-core
kernel-core-5.8.16-300.fc33.x86_64
kernel-core-5.9.11-200.fc33.x86_64
kernel-core-5.9.12-200.fc33.x86_64

uname -r >> 5.8.16-300.fc33.x86_64

So the system keeps booting from the old Kernel & however, in the /boot Directory I can’t see the freshly installed Kernels but I can see the initramfs Images. Weird…


Installed Kernels and initramfs in /boot

Also in the /boot/loader/entries Directory I can’t find any conf files related the the new kernel 5.9., onlky the conf file related to my actual booting kernel 5.8.16.

bootctl is not installed, only grub2.

Anyone have maybe any Idea what this could be?

Thanks!

Post the output:

lsblk -o +FSTYPE,UUID; cat /etc/default/grub; \
grep -v -e ^# -e ^$ /etc/fstab; df -h /boot

Also try to regenerate the relevant configs/initramfs:
Boot ends in Dracut Emergency Shell with warning that root device does not exist
And post that output as well.

Hi,

When trying to generate the configs/initramfs I getting a error message that a modul is missing:

insmod: ERROR: could not load module blscfg

Looks wrong.
Restore the defaults:

sudo mv -f /etc/default/grub{,.bak}
sudo tee /etc/default/grub << "EOF" > /dev/null
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="rd.lvm.lv=fedora/root rhgb quiet"
GRUB_DISABLE_RECOVERY="true"
GRUB_ENABLE_BLSCFG=true
EOF

And regenerate the configs/initramfs once again.

Unbelievable… You just made my day:).

It is working now, OS boots with Kernel 5.9.12 as desired.

Thanks!
