[ANSWERED] - Error installing docker on Ubuntu Bionic on a C1


Hi there,

I am getting this error when running docker on Ubuntu Bionic on a C1:

2018/08/21 12:02:54.395109 system_key.go:127: cannot determine nfs usage in generateSystemKey: cannot parse /etc/fstab: cannot parse dump frequency: "system"

I noticed that when I installed docker via apt-get, I got this error:

Setting up initramfs-tools (0.130ubuntu3.1) ... update-initramfs: deferring update (trigger activated) Processing triggers for initramfs-tools (0.130ubuntu3.1) ... update-initramfs: Generating /boot/initrd.img-4.15.0-32-generic Unsupported platform. run-parts: /etc/initramfs/post-update.d//flash-kernel exited with return code 1 dpkg: error processing package initramfs-tools (--configure): installed initramfs-tools package post-installation script subprocess returned error exit status 1 Errors were encountered while processing: initramfs-tools

This error persist whenever I try to install things or running at dpk --configure -a.

Is there a way to fix it?



You cannot use a native kernel on a baremetal instance. Baremetal C1 instance use bootscript.

How can I reproduce your problem?

Best regards



Whenever you write something like sudo apt-get install xxx (say, docker), it happens.


I have instantiated a C1 with Ubuntu Bionic and I cannot reproduce your error. Have you tried with a new instance? Can you provide me a script that reproduce your error from a new C1 instance?

Best regards



any update? I have the same problem , BIonic and C1 Server, I created three days ago


Before doing an upgrade could you try doing:

apt purge --auto-remove "linux-image-*" linux-base linux-firmware "grub*"


@sieben It actually got worse. Doing what you suggested got me this:
