Ubuntu Boot Issues

BRRABill

I'll be interested to see what you come up with, as I went through the same thing a while back.

I ended up jut deleting almost every unused kernel, and that fixed it up for me.

Always use autoremove IMO.

I not sure what should be removed, but reading father down the article suggests just running sudo apt-get autoremove and this should be fine.

Welcome to one of the many unpolished bits of Ubuntu compared to the other enterprise Linux offerings. It needs manual maintenance of updates. It's ridiculous. Yes, the autoremove option is the proper way to handle it.

Running that - manage to not be a member of the sudo file

See you can run visudo to add, but still get same error. this is after signing out and back in.

How did you edit that file if you were not in that file?

Also, the sudoers file is not an appropriate place to store who is and who is not granted sudo access.

please detail. It's easy enough to revert this file back to original and do 'correctly'.

BRRABill

I did all the auto removes and it still did not remove.

From my Googling of the issue, it was a common problem.

The proper way to handle this is to have sudoers tell which group(s) are the one with access. The best group for this is the wheel group as that has been the admin group for UNIX since the beginning of time (IT time, at least.) Then you add yourself to the proper group. The sudoers file itself should not be a hodge podge of access permissions.

Just ran into that same problem. Still showing 98% used.

You should put them in /etc/sudoers.d/

Just create a file with whatever groups/users permissions for that local system.

All of the .d directories are dump directories. It makes it easier to copy configs between systems.

I have found with newer versions of Ubuntu (16.04 and 16.10) that "apt-get autoremove" won't remove kernels, but "apt autoremove" will.

I tried everything online, and nothing worked. I had to remove them manually.

Actually, I think it was so full, it wouldn't run anything.

It was a while ago...

Does this seem correct?

Open terminal and check your current kernel:

uname -r
DO NOT REMOVE THIS KERNEL!

Next, type the command below to view/list all installed kernels on your system.

dpkg --list | grep linux-image
Find all the kernels that lower than your current kernel. When you know which kernel to remove, continue below to remove it. Run the commands below to remove the kernel you selected.

sudo apt-get purge linux-image-x.x.x.x-generic
Finally, run the commands below to update grub2

sudo update-grub2
Reboot your system.

I'm not sure if that worked for me either.

I had to manually remove them.

I did not update grub

Any attempt to remove old packages results in:

~$ sudo apt-get purge linux-image-3.13.0-48-generic
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 linux-image-extra-3.13.0-105-generic : Depends: linux-image-3.13.0-105-generic but it is not going to be installed
 linux-image-generic : Depends: linux-image-3.13.0-105-generic but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

Have you tried the suggestion yet?

apt-get -f install

Yes, and the above is the result.

Ah, the issue appears to be that you allowed the disk to fill to a point that the automated tools can no longer manage it.

cd into /boot and give us an ls
