Kernel update not working on ubuntu 13.10 server

Asked by Wenceslaus Dsilva

Hi Everyone,

I have run a apt-get update and upgrade command on one of our AWS servers and there was a kernel update which I wanted to upgrade.
I selected yes but it got stuck "Searching for GRUB installation directory ... found: /boot/grub" and I could not cancel the operation as well.

I tried steps from all over the internet but it did not work. So I ended up on the following link https://help.ubuntu.com/community/PackageManagerTroubleshootingProcedure

And I followed the steps in point 5

here is the output of those command and got stuck the same way like before after running sudo apt-get --purge autoremove:-

Ok what is the output of:

sudo dpkg --configure -a

Revision history for this message
Manfred Hampl (m-hampl) said : 		#6

Try again with the commands

sudo dpkg --configure -a
sudo apt-get upgrade

In case that one of the commands seems to be stuck, don't get impatient. Give it at least ten minutes before you try interrupting it.

What you see now, most probably is a consequence of the failed installation attempts.
You have to be aware that the package management system tries to make sure that only one package management program is running at a time (to avoid concurrent update problems). Apparently there is still a process running (probably stalled), that blocks one of the package management files and prevents all further updates.

Proposals for solution:
1. rebooting (if easily possible for your server system)
or
2. "sudo fuser -vvv /var/cache/debconf/config.dat" to identify the process that locks that file for killing the process.

Then try
sudo dpkg --configure -a
sudo apt-get upgrade
again.

How long did you wait for the package management to finish?
Is there any process running with high CPU usage?

What happens if you try the command

sudo update-grub

Does it also hang at "Searching for GRUB installation directory ... found: /boot/grub"?

with the dpkg command it took like 10 mins but now with the apt-get upgrade its still stuck
for searching for GRUB it takes a few seconds and then gets stuck after that

I am trying to exit out of the of apt-get upgrade but I am unable too, as soon as it finishes I will try the command mentioned by you and post the results here

Ok i did something....
put the command in the background i.e. the apt-get upgrade
and ran the command given by Manfred i.e. sudo fuser -vvv /var/cache/debconf/config.dat
killed a process called "frontend"
and then brought the apt-get upgrade command in the foreground

which gave me this

   â The grub-pc package is being upgraded. This menu allows you to select which devices you'd like grub-install to be automatically run for, if any. â
   â â
   â Running grub-install automatically is recommended in most situations, to prevent the installed GRUB core image from getting out of sync with GRUB modules or grub.cfg. â
   â â
   â If you're unsure which drive is designated as boot drive by your BIOS, it is often a good idea to install GRUB to all of them. â
   â â
   â Note: it is possible to install GRUB to partition boot records as well, and some appropriate partitions are offered here. However, this forces GRUB to use the blocklist mechanism, â
   â which makes it less reliable, and therefore is not recommended. â

I am not completely sure what there is happening on your system.
The dialogue "Configuring grub-pc - The grub-pc package is being upgraded." is coming unexpected for me.

The only thing that I can conclude is that there is apparently something wrong in your grub installation, but I do not have a clue how to proceed.

Maybe the advice to run "sudo update-grub" was not correct for your system, it might be possible that your system needs "sudo update-grub-legacy-ec2" instead.

Ok... I am trying to run the command now i.e. sudo update-grub-legacy-ec2
I will post the output in sometime

Can you help with this problem?
