Safe to reinstall kernel?

[Danny Horne]

Hi all,

A few days ago I updated through dnfdragora, that update included kernel
4.16.6.  Some way through the update my PC froze, and after leaving it
for a while decided the only option was a hard reset.

The PC still boots to kernel 4.16.5, and there's no trace of 4.16.6 in
the /boot directory.  DNF reports that kernel, kernel-core,
kernel-modules and kernel-modules-extra are installed (all 4.16.6).

Would it be safe to reinstall the kernel?  Or is there a better way to
get things up to date?

Thanks for looking

[Roger Heflin]

Reinstalling any rpms you have a reason to suspect have issues should
be just fine.   I have personally reinstalled the kernel rpm a number
of times when the update aborted before completion.

Tried 'dnf reinstall kernel' and that hasn't changed anything.  Still no
4.16.6 kernel in the /boot directory and 4.16.5 is the latest listed in
/boot/grub2/grub.cfg

Multiple versions of kernels are installed, so you will have to
explicitly give it the version you want it to reinstall.

grep -i kernel /var/log/dnf.log to get the full names you need to reinstall.

And the kernel is split in many RPMs.

I suspect that the posttrans scripts of the kernel-core and/or
kernel-modules RPMs haven't been done due to the hard reset.

Try that:

rel=<the full version you want: ex: 4.16.5-200.fc27.x86_64>
  dnf reinstall kernel-core-$rel kernel-modules-$rel

You may try also to only run the posttrans scripts of those RPMs.

See: rpm -q --scripts kernel-core-$rel kernel-modules-$rel

Thanks, reinstalling as you've described has fixed the issue, now
booting to 4.16.6

It would appear that it installed some of the items, but not others.
The reinstall would only reinstall packages that were already fully installed.

dnf upgrade

would probable complete the process

I generally do.
dnf clean all; dnf update -y

To see what all is installed you could
rpm -qa | grep -i kernel

The see what it shows.
