How do I get /sbin/init to install?

  1. My boot started failing indicating no /sbin/init after an update.

  2. Lots of playing around with gparted, grub, supergrub2...

  3. So I created a bootable gparted disk.

  4. Mounted my / and found it to be intact, /sbin is present but missing /sbin/init.

  5. Stumbled on No /sbin/init after upgrading to ubuntu 15.

  6. Found How to restore a system after accidentally removing all kernels?

  7. Went through the mount, chroot procedure outlined in restore procedure.

  8. The procedure is for an upgrade to 15.04 from 14.04, but I want stay with 14.04, so I am using a reinstall. Its failing and I don't know where to go from here.

  9. Aslo tried to reinstall upstart as per Restoring /sbin/init from Live CD, failed with a dpkg error processing fontconfig (see output below).

Never lose your hopes!

I've also faced a crash after apt-get install has installed some new packages... and at next reboot BANG! /sbin/init: No such file or directory. Also said /etc/init: Permission denied. Also said /bin/sh: 0: can't access tty; job control turned off.

Filesystem remained untouched at /dev/vda1 and fsck.ext4 returned: clean!

After a loooong research session, this worked for me: +1 to hill - a user from launchpad.

  1. boot your droplet with a Recovery ISO - TigerShark
  2. Network must be configured, either manually or via TigerShark script.
  3. mount -rw -o remount /dev/vda1 /mnt
  4. chroot /mnt
  5. unlink /etc/resolv.conf && echo "nameserver 8.8.8.8" > /etc/resolv.conf
  6. apt-get install init
  7. update-initramfs -u

After reboot your system. It will work fine. Enjoy!

Easiest solution? Full reinstall of your OS. Mark the packages you have installed and backup your /home and other related files/folders (unless you have /home on another partition (good for you!)), then reinstall, writing over the old broken OS partition.

  • yes, i do have a separate /home partition. I have a lot of "stuff" on this box, all sorts of tools, docker, vbox, ... How do do a full reinstall that does not kill all of my installs? I'm two days into this, easy would be nice but, I'm willing to try complicated if it will work.

  • @TimR You should probably just go through and copy all of the personal files such as documents, pictures, etc. to a USB or external storage device. As for the installed packages such as tools, docker, etc. Just make a list of the names of the programs that you had installed and reinstall them after you reinstall the OS.

  • @OwenHines I understand I may have to do that, however its not my first choice. The disk didn't crash, I can mount it and it appears to be ok. If I have to go that route I'd like to learn something, like where does /sbin/init come from, what deletes it, and what installs it. Also, there are a couple of error msgs in the above captures having to do with dpkg and fontconfig. I do appreciate your taking the time to answer - thanks

  • @TimR I don't have an explanation for you, but I did want to say that you wanting to get something out of this for learning is a great mindset to have. Always apply that to problems. Keep it up!
