Latest kernel update (27-05-24) fails to install

On attempting to install updates available today on my Grommunio Appliance (built from 15-04 ISO) on a Proxmox 8.x host) the following items were found to be available:-

v | grommunio | grommunio-cui | 1.0.268.f207513-lp155.68.1 | 1.0.270.2b57c48-lp155.70.1 | noarch
v | grommunio | grommunio-setup | 1.0.109.048c9c5-lp155.48.1 | 1.1.1.b985a59-lp155.51.1 | noarch
v | grommunio | gromox | 2.28.12.gdf8059d-lp155.31.1 | 2.28.12.gdf8059d-lp155.32.1 | x86_64
v | grommunio | gromox-debuginfo | 2.28.12.gdf8059d-lp155.31.1 | 2.28.12.gdf8059d-lp155.32.1 | x86_64
v | grommunio | gromox-debugsource | 2.28.12.gdf8059d-lp155.31.1 | 2.28.12.gdf8059d-lp155.32.1 | x86_64
v | repo-sle-update | kernel-default | 5.14.21-150500.55.62.2 | 5.14.21-150500.55.65.1 | x86_64

All installed OK except the kernel-default which reported an exit code '1'. An inspection of the /var/log/grommunio-update.log file suggested that the issue may have been insufficient disc space in the /boot volume, suggesting my Appliance was about 37MB short or space.

After a quick Google I issued the command:-

rpm -qa | grep -i 'kernel-default-5'

which showed the following kernels were present:-

kernel-default-5.14.21-150500.55.52.1.x86_64
kernel-default-5.14.21-150500.55.59.1.x86_64
kernel-default-5.14.21-150500.55.62.2.x86_64

The /etc/zypp/zypp.conf file suggested only the latter 2 kernels should be present.

multiversion.kernels = latest,latest-1,running

Running 'zypper purge-kernels' removed the oldest package (that should have been removed on the last reboot)

rpm -qa | grep -i 'kernel-default-5' now shows the oldest kernel has been removed.

kernel-default-5.14.21-150500.55.59.1.x86_64
kernel-default-5.14.21-150500.55.62.2.x86_64

Re-running Update from the Grommunio Admin GUI now correctly installs the new kernel, however, after the reboot rpm -qa | grep -i 'kernel-default-5' shows the following kernels are installed.

kernel-default-5.14.21-150500.55.59.1.x86_64
kernel-default-5.14.21-150500.55.62.2.x86_64
kernel-default-5.14.21-150500.55.65.1.x86_64

When the next kernel update is released the install will fail again as the /boot volume will again have insufficient space to allow the new kernel to be installed. It appears that the process that run the 'purge-kernels' command/script on boot up is not being executed as it used to. Fortunately, running ing the script manually works.

Hope this helps others if they see the kernel update failure.

crpb Thanks for this. I can confirm that the 'purge-kernels-service' was not installed when I built my latest VM's using the 15-04 Appliance ISO.

I have now installed the 'purge-kernels-service' into my Grommunio appliances, so hopefully no more kernel install faults like this one.

Thanks again for the insight to the issue.
