Updating kernel using aptitude

, this Makefile is used to build new kernels (this is how we are building the Scaleway kernels), but it won't help you to update it on your server, the only way is to change your bootscript (see https:// Cheers @moul thanks for thorough answer.

I'm trying to install flynn (flynn.io) and here's the issue flynn/flynn#2696 . Ok nice, can you just try to use the Docker bootscript then ?

With Lenny the same kernel can be used, or the standard Debian xen kernel (2.6.26 based) can be used instead.

Tried to reinstall kernel according to your docs, first it needed apt-get install gcc and apt-get install libssl-dev , otherwise the process would fail.

Ofcourse being able to load the kernel from the disk image would be preferable but I would imagine this is somewhat more difficult without reasonably sophisticated boot infrastructure to first boot an initrd to mount the rootfs, parse the local bootloader configuration, get the guest kernel, push this to somewhere that you can get on the next reboot and cycle the machine. I suggest you to look at this schema: https://github.com/scaleway/initrd/tree/master/Linux#schema-boot-timeline In short: we are attaching your volumes (disks) using NBD which is not handled by the boot loaders (u-boot for C1, ipxe for VPS and C2*), so we can't get your kernel from your That's exactly what I understood yesterday, I will try to add a script that sync everything needed to build new modules easily using DKMS, so I can add ZFS to fix this issue, but also improve the ease of customisation for every other usages thanks for confirming the idea Failing that you should probably just also package your kernels for the distros so that people are able to install them to the local disk even if they won't be used so that kernel modules not required to boot the server can be built against them and stored on the network disk and modprobed after system startup.

That said, let's see how to uninstall old kernel images on Ubuntu platform.

GRUB boot manager maintains GRUB entries for each old kernel, in case you want to boot into it.

As part of disk cleaning, you can consider removing old kernel images if you haven't used them for a while.

There are always some security risks involved in running software upgrades without supervision, but there are also benefits.

If you believe it's important to stay up to date with the latest security patches, then you should follow this simple tutorial.
