mount -a

Proxmox was installed with SDR and after an update the newly installed kernel is not loaded. How can this be fixed?​

This is due to a bug in the AppliPACK. To fix this you have to log in to the command line as root user and follow the steps below:

  • Find out the version of the new kernel. To do this, find the highest version of a vmlinuz file in the /boot directory and note it (e.g. 4.15.18-20-pve).

  • Mount partition /dev/sda3 to temporary location:

mount /dev/sda3 /mnt
  • Unmount EFI-Partition:
umount /boot/efi
  • Copy the complete contents of /boot to /dev/sda3:
cp -a /boot/* /mnt/
  • Unmount partition sda3:
umount /mnt
  • Delete contents of /boot
rm -Rf /boot/*
  • Add line to the /etc/fstab file:
echo "/dev/sda3 /boot ext4 defaults 0 1" >> /etc/fstab
  • Mount all file systems again:
mount -a
  • PostInstall the kernel manually. Use the version of the latest kernel instead of KVERSION:
/var/lib/dpkg/info/pve-kernel-KVERSION.postinst configure
  • Activate kernel with reboot
 reboot
